119-461: Cherokee Lake , also known as Cherokee Reservoir , is an artificial reservoir in the U.S. state of Tennessee formed by the impoundment of the Holston River behind Cherokee Dam . The reservoir has a surface area of about 28,780 acres (11,650 ha), a flood -storage capacity of 749,406 acre-feet (924,379,000 m), and nearly 400 miles (640 km) of shoreline. In a normal year,

238-602: A cutbait . Common natural baits for both fresh and saltwater fishing include earthworm , leech , insects and larvae , minnow , squid , prawn , crayfish , and even crabs, frogs and salamanders . Natural baits are effective due to the real texture, odour and movements of the bait presented. The common earthworm is a universal live bait for freshwater angling, and grubs and maggots are also excellent bait when trout fishing . Grasshoppers , crickets , eels and even ants are also used as bait for trout in their season, although many anglers believe that trout or salmon roe

357-417: A dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be on-stream reservoirs , which are located on the original streambed of the downstream river and are filled by creeks , rivers or rainwater that runs off the surrounding forested catchments, or off-stream reservoirs , which receive diverted water from

476-518: A human arm ) and increasing the launch speed of the terminal tackles (the hook, bait/lure, and other co-launched attachments such as float and sinker / feeder ). Traditional fishing rods are made from single piece of hardwood (e.g. ash and hickory ) or bamboo , while contemporary rods are usually made from alloys (e.g. aluminium ) or more often high-tensile composite materials such as fibreglass or carbon fiber , and newer rod designs are often constructed from hollow blanks to increase

595-559: A " direct-drive " design, while modern reels since the Industrial Revolution typically are "multiplier" reels that use internal gear trains to gain a higher rotational speed . Most reels made from the latter half of the 20th century onwards have smoother line guides, anti-reverse designs, gear disengagement mechanisms and sophisticated drag and braking adjustments to help casting farther, more accurately and reliably, and to provide optimal pulling forces when retrieving

714-537: A block for migrating fish, trapping them in one area, producing food and a habitat for various water-birds. They can also flood various ecosystems on land and may cause extinctions. Creating reservoirs can alter the natural biogeochemical cycle of mercury . After a reservoir's initial formation, there is a large increase in the production of toxic methylmercury (MeHg) via microbial methylation in flooded soils and peat. MeHg levels have also been found to increase in zooplankton and in fish. Dams can severely reduce

833-455: A certain size range must be released alive after capture. The popular fish species pursued by anglers, collectively known as game fish , vary with geography. Among the many species of saltwater fish that are angled for sport globally are billfish ( swordfish , sailfish and marlin ), tuna , trevally and grouper , while cod and sea bass are popular targets in Europe. In North America,

952-658: A conventional oil-fired thermal generation plant. For instance, In 1990, the impoundment behind the Balbina Dam in Brazil (inaugurated in 1987) had over 20 times the impact on global warming than would generating the same power from fossil fuels, due to the large area flooded per unit of electricity generated. Another study published in the Global Biogeochemical Cycles also found that newly flooded reservoirs released more carbon dioxide and methane than

1071-533: A drop of water seep into the ocean without benefiting mankind." He created the reservoir named Parakrama Samudra ("sea of King Parakrama"). Vast artificial reservoirs were also built by various ancient kingdoms in Bengal, Assam, and Cambodia. Many dammed river reservoirs and most bank-side reservoirs are used to provide the raw water feed to a water treatment plant which delivers drinking water through water mains. The reservoir does not merely hold water until it

1190-747: A fish from unhooking itself while being reeled in. Some laws and regulations require hooks to be barbless, typically to facilitate catch and release . This rule is commonly implemented to protect populations of certain species, as a barbed hook could cause significant collateral lacerations (especially when it penetrates the gill) that can kill a fish even after released alive. Fishing lines are long, ultra-thin, flexible cords that may come in monofilament or braided multifilament forms. Traditional fishing lines are made of silk, while most modern fishing lines are made from synthetic polymers such as nylon, polyethylene , polyvinylidene fluoride (" fluorocarbon ") or copolymer materials. Important specifications for

1309-423: A fishing line include its material and forms, test weight , diameter, stretch , memory , abrasion resistance, UV resistance, and reflective and/or refractive visibility. A fishing rod is a long, thin stick/pole that acts as an extended lever and allows the angler to amplify line movements while luring and pulling the fish. It also enhances casting distance by lengthening the swing radius (compared to that of

1428-448: A fishing line. Almost all recreational angling activities involve the use of fishing rods , which is used to manipulate the movements of fishing lines and to allow farther casting of baits / lures . The main rod fishing techniques are float fishing , bottom fishing , lure fishing and trolling , while the former two are often collectively known as "bait fishing" due to the exclusive use of conventional edible baits. Float fishing

1547-455: A high-level reservoir is filled with water using high-performance electric pumps at times when electricity demand is low, and then uses this stored water to generate electricity by releasing the stored water into a low-level reservoir when electricity demand is high. Such systems are called pump-storage schemes. Reservoirs can be used in a number of ways to control how water flows through downstream waterways: Reservoirs can be used to balance

1666-441: A laterally flattened float called palyaw , which is shaped like a small outrigger boat , a catamaran or a fish. A longline is attached to the float, and set unto the water's edge and dragged by someone running or walking along the beach. The combination of the water resistance and the diagonal pull forces the float outwards into deeper waters, like a kite . Once the line reaches its maximum line length, it moves rapidly parallel to

1785-412: A longline vertically down into the water (instead of being more horizontally deployed like longlining) with a series of baited hooks. Droplines are weighted at the bottom and have a float at the top. They are not usually as long as longlines and have fewer hooks, and tend to be stationary. Trotlining uses a longline that, instead of being tethered to the water surface only at one end, are fixed at/near

1904-570: A loss in both quantity and quality of water necessary for maintaining ecological balance and pose a risk of increasing severity and duration of droughts due to climate change. In summary, they consider it a misadaptation to climate change. Proponents of reservoirs or substitution reserves, on the other hand, see them as a solution for sustainable agriculture while waiting for a truly durable agricultural model. Without such reserves, they fear that unsustainable imported irrigation will be inevitable. They believe that these reservoirs should be accompanied by

2023-460: A lure they have just been hooked on, a behaviour that is unlikely if hooking were painful. Opponents of catch and release fishing would find it preferable to ban or to severely restrict angling. On the other hand, proponents state that catch-and-release is necessary for many fisheries to remain sustainable, is a practice that generally has high survival rates, and consider the banning of angling as not reasonable or necessary. In some jurisdictions, in

2142-419: A narrow valley or canyon may cover relatively little vegetation, while one situated on a plain may flood a great deal of vegetation. The site may be cleared of vegetation first or simply flooded. Tropical flooding can produce far more greenhouse gases than in temperate regions. The following table indicates reservoir emissions in milligrams per square meter per day for different bodies of water. Depending upon

2261-530: A national policy was New Zealand in 1986. The minimum landing size (MLS) is the smallest fish measurement at which it is legal for the fisherman to keep a captured fish. The MLS depends on the species of fish, and allowed sizes also vary around the world, as they are legal definitions which are defined by the local regulatory authority. The idea behind this limitation is that only the older, more mature adult fish get taken, leaving growing juveniles behind to continue breeding and propagating their species. There

2380-470: A nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically located at a narrow part of a downstream of a natural basin. The valley sides act as natural walls, with the dam located at the narrowest practical point to provide strength and the lowest cost of construction. In many reservoir construction projects, people have to be moved and re-housed, historical artifacts moved or rare environments relocated. Examples include

2499-611: A reservoir is called the "conservation pool". In the United Kingdom, "top water level" describes the reservoir full state, while "fully drawn down" describes the minimum retained volume. There is a wide variety of software for modelling reservoirs, from the specialist Dam Safety Program Management Tools (DSPMT) to the relatively simple WAFLEX , to integrated models like the Water Evaluation And Planning system (WEAP) that place reservoir operations in

2618-450: A river of variable quality or size, bank-side reservoirs may be built to store the water. Such reservoirs are usually formed partly by excavation and partly by building a complete encircling bund or embankment , which may exceed 6 km (4 miles) in circumference. Both the floor of the reservoir and the bund must have an impermeable lining or core: initially these were often made of puddled clay , but this has generally been superseded by

2737-740: A river valley, with the potential to wash away towns and villages and cause considerable loss of life, such as the devastation following the failure of containment at Llyn Eigiau which killed 17 people. (see also List of dam failures ) A notable case of reservoirs being used as an instrument of war involved the British Royal Air Force Dambusters raid on Germany in World War II (codenamed " Operation Chastise " ), in which three German reservoir dams were selected to be breached in order to damage German infrastructure and manufacturing and power capabilities deriving from

2856-691: A single species in a single fishing ground ) around the world had adopted some variant of this approach, along with approximately 100 smaller fisheries in individual countries. Approximately 10% of the marine harvest was managed by ITQs as of 2008. The first countries to adopt individual fishing quotas were the Netherlands , Iceland and Canada in the late 1970s, and the most recent is the United States Scallop General Category IFQ Program in 2010 The first country to adopt individual transferable quotas as

2975-429: A smaller size survive longer to continue breeding, and the average size of fish stock shrinks over time. This has led to a collapse in the amount of catchable fish in some fisheries. Although most anglers keep their catch for consumption, catch and release fishing is increasingly practiced, especially by fly anglers. The general principle is that releasing fish allows them to survive, thus avoiding unintended depletion of

3094-447: A successful catch. Sometimes a hand net (or "landing net") or a long-handled hook is used to make fetching the fish easier. Angling is the principal method of recreational fishing , but commercial fisheries also use angling methods such as longlining , trotlining or trolling . In many parts of the world, a fishing licence is mandated for angling and size limits apply to certain species, meaning by law, fish below and/or above

3213-582: A territorial project that unites all water stakeholders with the goal of preserving and enhancing natural environments. Two main types of reservoirs can be distinguished based on their mode of supply. Circa 3000 BC, the craters of extinct volcanoes in Arabia were used as reservoirs by farmers for their irrigation water. Dry climate and water scarcity in India led to early development of stepwells and other water resource management techniques, including

3332-402: A watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. The term is also used technically to refer to certain forms of liquid storage, such the "coolant reservoir" that captures overflow of coolant in an automobile's cooling system. Dammed reservoirs are artificial lakes created and controlled by

3451-399: Is a bass fishing technique that resembles jigging , and involves repetitively lifting and dropping a flat lure, usually made of 1 to 2.5 oz of lead painted to look like a baitfish (or heavy slabs of metal), through a school of actively feeding fish that the angler has located on a fishfinder . It is used on white and striped bass in the reservoirs of the southern US. Rodless trolling

3570-476: Is a natural lake whose level was raised by a low dam and into which the River Dee flows or discharges depending upon flow conditions, as part of the River Dee regulation system . This mode of operation is a form of hydraulic capacitance in the river system. Many reservoirs often allow some recreational uses, such as fishing and boating . Special rules may apply for the safety of the public and to protect

3689-484: Is a water reservoir for agricultural use. They are filled using pumped groundwater , pumped river water or water runoff and are typically used during the local dry season. This type of infrastructure has sparked an opposition movement in France, with numerous disputes and, for some projects, protests, especially in the former Poitou-Charentes region where violent demonstrations took place in 2022 and 2023. In Spain, there

3808-590: Is also home to a sailing club and regattas are hosted seasonally on its waters. Since the lake has a greater fish density than most reservoirs maintained by the TVA, it has become one of the most popular for anglers in the East Tennessee region. In 2019, Cherokee Lake was ranked #20 by Bassmaster of the top 25 bass fishing lakes in the Southeastern United States . In October 2020,

3927-581: Is designed to contain and release groundbaits to help attract fish towards the hook. Lure fishing uses a type of artificial fake bait known as lure , which is usually made from inedible materials such as wood, metal and plastics. Unlike conventional fishing baits, lures do not emit any scent and thus cannot attract fish olfactorily, but instead using prey-like appearances, movements, vibrations, bright reflections and flashy colors to attract and entice carnivorous predatory fish into mistakenly striking. Many lures are equipped with more than one hooks to better

4046-679: Is fraught with substantial land submergence, coastal reservoirs are preferred economically and technically since they do not use scarce land area. Many coastal reservoirs were constructed in Asia and Europe. Saemanguem in South Korea, Marina Barrage in Singapore, Qingcaosha in China, and Plover Cove in Hong Kong are a few such coastal reservoirs. Where water is pumped or siphoned from

4165-688: Is generally accepted that this management approach will help the fishery create a number of large, trophy-sized fish. In smaller fisheries that are heavily fished, catch and release is the only way to ensure that catchable fish will be available from year to year. The practice of catch and release is criticised by some who consider it unethical to inflict pain upon a fish for purposes of sport. Some of those who object to releasing fish do not object to killing fish for food. Adherents of catch and release dispute this charge, pointing out that fish commonly feed on hard and spiky prey items, and as such can be expected to have tough mouths, and also that some fish will re-take

4284-501: Is greater acceptance because all beneficiary users are involved in the implementation of the system. The specific debate about substitution reservoirs is part of a broader discussion related to reservoirs used for agricultural irrigation, regardless of their type, and a certain model of intensive agriculture. Opponents view these reservoirs as a monopolization of resources benefiting only a few, representing an outdated model of productive agriculture. They argue that these reservoirs lead to

4403-428: Is increasingly practiced by sport fishermen in recent years to conserve the fish stocks and help maintain sustainability of the local fisheries. Angling is not to be confused with snagging , another fishing technique that also uses line and hook to catch fish. The principal differences between the two techniques are that angling often uses very small hooks and relies on the target fish itself to voluntarily swallow

4522-466: Is needed: it can also be the first part of the water treatment process. The time the water is held before it is released is known as the retention time . This is a design feature that allows particles and silts to settle out, as well as time for natural biological treatment using algae , bacteria and zooplankton that naturally live in the water. However natural limnological processes in temperate climate lakes produce temperature stratification in

4641-536: Is now used by the Aquarius Golf Club. Service reservoirs perform several functions, including ensuring sufficient head of water in the water distribution system and providing water capacity to even-out peak demand from consumers, enabling the treatment plant to run at optimum efficiency. Large service reservoirs can also be managed to reduce the cost of pumping by refilling the reservoir at times of day when energy costs are low. An irrigation reservoir

4760-531: Is poorly suited to forming a single large reservoir, a number of smaller reservoirs may be constructed in a chain, as in the River Taff valley where the Llwyn-on , Cantref and Beacons Reservoirs form a chain up the valley. Coastal reservoirs are fresh water storage reservoirs located on the sea coast near a river mouth to store the flood water of a river. As the land-based reservoir construction

4879-1087: Is prepared from a small amount of bread, often moistened and softened by saliva, then squeezed into a ball of the bite size of small fish. Some baits are not actual food items but rather just "fake" replicas of food made of inedible materials (e.g. wood, metal, silicone rubber , plastics, etc), and are designed to entice predatory fish to strike by imitating the appearance and motions of real prey ( shad , worm, frog, insect, crayfish , etc.). These inedible, replica baits are typically called lures instead of baits, although expressions such as " swimbaits ", "crankbaits", "jerkbaits", " spinnerbaits " and "chatterbaits" are still used when describing specific types of lures. Unlike conventional baits, lures typically do not release any scents and rely solely on looks and sounds/vibrations to attract fish, although occasionally chemical attractants (e.g. dimethyl-β-propiothetin ) are still used in addition either to impregnate favorable smells or to mask away unwanted plastic smells. Many anglers prefer to fish solely using lures, as these rely more on

4998-439: Is some criticism of this legal requirement, however, as it applies artificial selection pressure to the fish population (see Fisheries-induced evolution ) unless the anglers voluntarily practise catch and release indiscriminate of sizes. As larger fish (whose survival has been more successful so far) get taken out of the population, the genes for larger size are reduced or removed from the gene pool , while fish that mature at

5117-419: Is stored in the reservoir. Any excess water can be spilled via a specifically designed spillway. Stored water may be piped by gravity for use as drinking water , to generate hydro-electricity or to maintain river flows to support downstream uses. Occasionally reservoirs can be managed to retain water during high rainfall events to prevent or reduce downstream flooding. Some reservoirs support several uses, and

5236-516: Is superior to any other bait. Crayfish, which are preyed upon by a variety of ray-finned fishes , are also commonly used as bait, either live or with only the tail meat. They are popular for catching catfish , largemouth bass , smallmouth bass , striped bass , perch and pike . However, studies had confirmed that introducing crayfish outside of their home range has led to various ecological problems of them becoming invasive species . Transporting crayfish as live bait has also contributed to

5355-496: Is the most common method of angling, defined by the use of a compact light buoy attached to fishing line – known as a float (or " bobber " in the United States) — as the bite indicator . Due to buoyancy, the float remains at the water surface and suspends the baited hook at a predetermined depth. It can also drift in the prevailing current and carry the hook to areas of water otherwise inaccessible by casting alone. When

5474-401: Is the oldest angling technique used by mankind, and can be done from boats or from the shore. It is used mainly to catch groundfish and squid , but smaller pelagic fish can also be caught. Deadlining is the practice of leaving a baited handline in the water (with the other end fastened to the bank ) and returning later (usually overnight) to check and capture any tethered fish, similar to

5593-473: Is the portion of the reservoir that can be used for flood control, power production, navigation , and downstream releases. In addition, a reservoir's "flood control capacity" is the amount of water it can regulate during flooding. The "surcharge capacity" is the capacity of the reservoir above the spillway crest that cannot be regulated. In the United States, the water below the normal maximum level of

5712-422: Is typically used in commercial fishing, with one or more baited lines drawn through the water behind a slow moving fishing boat that is usually equipped with outriggers , downriggers and trolling motors . Trolling is used to catch economic pelagic fish such as mackerel and kingfish . Pahila (literally meaning "pulled") is a Filipino traditional shoreline trolling, uniquely using baited hooks tied to

5831-538: Is used, and when the lure catches the attention of a game fish and successfully results in biting/swallowing of the lure, the angler can detect it by watching for splashes and feeling any vibrations, rod bending and changes in line tension. Lure fishing also typically uses relatively lightweight fishing rods coupled with baitcasting reels or spinning reels. Depending on the style of lure retrieval, lure fishing can roughly be separated into power fishing , which relies on more frequent and vigorous lure retrievals to increase

5950-534: The Canadian province of Manitoba , for example, catch and release is mandatory for some species such as brook trout . Many of the jurisdictions which mandate the live release of sport fish also require the use of artificial lures and barbless hooks to minimise the chance of injury to fish. Mandatory catch and release also exists in the Republic of Ireland where it was introduced as a conservation measure to prevent

6069-452: The Ruhr and Eder rivers. The economic and social impact was derived from the enormous volumes of previously stored water that swept down the valleys, wreaking destruction. This raid later became the basis for several films. All reservoirs will have a monetary cost/benefit assessment made before construction to see if the project is worth proceeding with. However, such analysis can often omit

6188-421: The specific strength and reduce the overall weight. Modern rods also may come in multi-piece or telescoping forms, which are more portable and storage-friendly. Fishing reels are manually cranked reels typically mounted onto a fishing rod, used to wind and stow fishing line when a long casting distance or a prolonged retrieval is expected. Traditional fishing reels are essentially compact windlasses with

6307-620: The 1800s, most of which are lined with brick. A good example is the Honor Oak Reservoir in London, constructed between 1901 and 1909. When it was completed it was said to be the largest brick built underground reservoir in the world and it is still one of the largest in Europe. This reservoir now forms part of the southern extension of the Thames Water Ring Main . The top of the reservoir has been grassed over and

6426-731: The Meroitic town of Butana . The Hafirs catch the water during rainy seasons in order to ensure water is available for several months during dry seasons to supply drinking water, irrigate fields and water cattle. The Great Reservoir near the Lion Temple in Musawwarat es-Sufra is a notable hafir in Kush. In Sri Lanka , large reservoirs were created by ancient Sinhalese kings in order to store water for irrigation. The famous Sri Lankan king Parākramabāhu I of Sri Lanka said "Do not let

6545-552: The TVA, is used for hydroelectric generation and flood control. The dam was built on a crash schedule; construction started August 1, 1940, and was completed on December 5, 1941. The dam and the reservoir were named after the Native American tribe of the same name by the TVA, as before the Holston's impoundment, the area was once inhabited by the tribe. The Great Indian Warpath, once used by pioneer Daniel Boone , lies in

6664-488: The US. The capacity, volume, or storage of a reservoir is usually divided into distinguishable areas. Dead or inactive storage refers to water in a reservoir that cannot be drained by gravity through a dam's outlet works , spillway, or power plant intake and can only be pumped out. Dead storage allows sediments to settle, which improves water quality and also creates an area for fish during low levels. Active or live storage

6783-493: The amount of water reaching countries downstream of them, causing water stress between the countries, e.g. the Sudan and Egypt , which damages farming businesses in the downstream countries, and reduces drinking water. Angling When angling, the fisherman (known as the angler ) will first throw the hook (i.e. " cast ") to a chosen area of water (i.e. fishing ground ), and then patiently wait for fish to approach and devour

6902-411: The angler's position; and hookbait , which is directly attached to the fish hook to entice the fish into swallowing the hook along with the bait. In colloquial usage, the word "bait" refers specifically to hookbaits, which can be further separated into three main categories: natural baits , artificial baits and lures . The choice of what bait to use is dictated mainly by the target species's diet,

7021-535: The area flooded versus power produced, a reservoir built for hydro- electricity generation can either reduce or increase the net production of greenhouse gases when compared to other sources of power. A study for the National Institute for Research in the Amazon found that hydroelectric reservoirs release a large pulse of carbon dioxide from decay of trees left standing in the reservoirs, especially during

7140-426: The bait/lure is allowed to drift and react freely to the turbulences in the water current, much like how a tethered kite would behave in a wind gust. Although all angling techniques use hook and line, the term "line fishing" specifically refers to those that do not involve using fishing rods. Handlining is angling with a handheld fishing line, baited with lures or bait fish just like normal rod angling. Handlining

7259-428: The base of the dam or some distance away. In a flat river valley a reservoir needs to be deep enough to create a head of water at the turbines; and if there are periods of drought the reservoir needs to hold enough water to average out the river's flow throughout the year(s). Run-of-the-river hydro in a steep valley with constant flow needs no reservoir. Some reservoirs generating hydroelectricity use pumped recharge:

7378-531: The basin of the reservoir. Cherokee Lake in recent times has seen a large transition into a popular recreational tourist destination . Public boating access areas, Panther Creek State Park and other public parks , commercial boat docks , lakefront resorts, RV and tent campgrounds, and a state wildlife management area on the shores of the lake attract extensive recreational use, such as swimming, boating, paddling activities (such as canoeing, kayaking and paddleboarding), camping, water sports, and fishing. The lake

7497-527: The best outcome for managing fish populations. Individual fishing quota (IFQ), also known as individual transferable quota (ITQ), is a kind of catch share that sets a species -specific total allowable catch (TAC), typically by weight and for a given time period. A dedicated portion of the TAC (called "quota share") is then allocated to individual fishermen, and can typically be transferable (i.e. bought, sold or leased). As of 2008, 148 major fisheries (generally,

7616-465: The build, often through a temporary tunnel or by-pass channel. In hilly regions, reservoirs are often constructed by enlarging existing lakes. Sometimes in such reservoirs, the new top water level exceeds the watershed height on one or more of the feeder streams such as at Llyn Clywedog in Mid Wales . In such cases additional side dams are required to contain the reservoir. Where the topography

7735-556: The building of a reservoir at Girnar in 3000 BC. Artificial lakes dating to the 5th century BC have been found in ancient Greece. The artificial Bhojsagar lake in present-day Madhya Pradesh state of India, constructed in the 11th century, covered 650 square kilometres (250 sq mi). The Kingdom of Kush invented the Hafir , a type of reservoir, during the Meroitic period . 800 ancient and modern hafirs have been registered in

7854-433: The chance of anchoring into the fish's mouth , though some hookless lures are used to bait the fish nearer so it can be captured via other means such as spearing , netting / trapping or capturing by hand . In addition to rod angling, handlining , longlining and commercial trolling also employ lure fishing. Lure fishing is a popular style of recreational fishing. When fishing, a lure angler will repeatedly cast out

7973-402: The chance of luring fish; and finesse fishing , which focuses on the more lingered and vivid lure presentation within each cast-retrieval cycle to better entice fish. Rod trolling is basically a simplified version of commercial trolling (see below ), with fishing rods functioning as improvised outriggers to tow the baits/lures through the water, usually behind or beside a moving boat with

8092-670: The communities of Jefferson City in Jefferson County, and Bean Station in Grainger County, for the construction of Cherokee Dam and the impounding of the Holston River for Cherokee Lake. Many residents, at first in refusal, would reluctantly give up their farms and homes for the promise of flood control and electricity offered by the TVA. For Bean Station, the Cherokee Project included wiping out

8211-442: The context of system-wide demands and supplies. In many countries large reservoirs are closely regulated to try to prevent or minimize failures of containment. While much of the effort is directed at the dam and its associated structures as the weakest part of the overall structure, the aim of such controls is to prevent an uncontrolled release of water from the reservoir. Reservoir failures can generate huge increases in flow down

8330-498: The decline of Atlantic salmon stocks on some rivers. In Switzerland, catch and release fishing is considered inhumane and was banned in September 2008. Barbless hooks, which can be created from a standard hook by removing the barb with pliers or can be bought, are sometimes resisted by anglers because they believe that increased fish escapes. Barbless hooks reduce handling time, thereby increasing survival. Concentrating on keeping

8449-504: The definition of angling since they do not rely upon the use of a hook and line. Fishing seasons are set by countries or localities to indicate what kinds of fish may be caught during sport fishing (also known as angling) for a certain period of time. Fishing seasons are enforced (usually by water police ) to maintain ecological balance and to protect species of fish during their spawning period during which they are easier to catch and more physiologically vulnerable. Slot limits prohibit

8568-530: The depths where water is released for hydroelectric generation. Silt loam , slate , and red clay are commonly found in the basin and surrounding shoreline of Cherokee Lake. Black bass , sauger , walleye , crappie , various sunfish , and the usual rough-fish species, are often found in the reservoir. From 1940 to 1942, the Tennessee Valley Authority (TVA) began purchasing property and performing acquisitions by eminent domain in

8687-460: The developed world Naturally occurring lakes receive organic sediments which decay in an anaerobic environment releasing methane and carbon dioxide . The methane released is approximately 8 times more potent as a greenhouse gas than carbon dioxide. As a human-made reservoir fills, existing plants are submerged and during the years it takes for this matter to decay, will give off considerably more greenhouse gases than lakes do. A reservoir in

8806-507: The downstream river to maintain river quality, support fisheries, to maintain downstream industrial and recreational uses or for a range of other purposes. Such releases are known as compensation water . The units used for measuring reservoir areas and volumes vary from country to country. In most of the world, reservoir areas are expressed in square kilometers; in the United States, acres are commonly used. For volume, either cubic meters or cubic kilometers are widely used, with acre-feet used in

8925-857: The entire lure package is known as a rig . Common rigs with a soft plastic lure are the Texas Rig or the Carolina Rig . Some fishing lures (e.g. spoons and spinnerbaits) may not even resemble any prey in looks, and may require skilled rod movements to impart an enticing presentation to the target fish, for example in jigging and topwater fishing . Some lures, such as the flies used in fly fishing , are ultralight and even require specialized gears and techniques to be cast properly. In modern times, there are also lures that photically attract fish with LED illuminiation, as well as battery-powered "bionic" lures that are essentially primitive robot fish that can swim around without needing to be towed by

9044-440: The environmental impacts of dams and the reservoirs that they contain. Some impacts, such as the greenhouse gas production associated with concrete manufacture, are relatively easy to estimate. Other impacts on the natural environment and social and cultural effects can be more difficult to assess and to weigh in the balance but identification and quantification of these issues is now commonly required in major construction projects in

9163-499: The first decade after flooding. This elevates the global warming impact of the dams to levels much higher than would occur by generating the same power from fossil fuels . According to the World Commission on Dams report (Dams And Development), when the reservoir is relatively large and no prior clearing of forest in the flooded area was undertaken, greenhouse gas emissions from the reservoir could be higher than those of

9282-514: The fish bites and swallows the hook, the float visually signals any forces exerted on the leader line below it, as the fisherman can then see it being pulled underwater and/or sideways. Bottom fishing, also called legering in the United Kingdom, uses a weighted tackle called a sinker tied to the end of the fishing line to keep the baited hook close to the bottom of the water, to target groundfishes such as sucker , bream , catfish and crappie . The sinker can also be used to add momentum to

9401-401: The fish in turn becomes firmly tethered by the fishing line. Once the fish is hooked (often colloquially called "fish-on"), any struggles and attempts to escape will pull along the line, causing the bite indicator to signal the angler, who jerks the fishing rod back to further deepen the hook anchorage (i.e. " setting the hook ") and then tries to retrieve the line back, pulling the fish closer in

9520-417: The float pulls the float deeper into the water, causing it to oscillates in and out of water in a bobbing -like fashion (hence its American English name, the "bobber"). Other bite indicators used in angling include: In angling, two broad types of baits are used: groundbait , which is thrown separately into the water in large quantities as an " appetizer " to olfactorily attract distant fish nearer to

9639-413: The flow in highly managed systems, taking in water during high flows and releasing it again during low flows. In order for this to work without pumping requires careful control of water levels using spillways . When a major storm approaches, the dam operators calculate the volume of water that the storm will add to the reservoir. If forecast storm water will overfill the reservoir, water is slowly let out of

9758-437: The habitat and weather conditions](which can alter the fish's foraging behavior), the angler's own personal preferences, and the local fishery regulations . Using an optimal angling bait can increase the chance of catching the intended fish, while conversely using an inadequate bait will greatly reduce the success rate, especially when there are other bait fishermen nearby. Natural baits are food items that are present within

9877-483: The harvest of fish where the measured lengths (from the snout to the end of the tail fin ) fall within a protected interval. These are put in action to help protect certain fish (usually juvenile ) in a given area. They generally require anglers to release captured fish if they fall within a given size range, allowing anglers to keep only smaller (though rare) or larger fish. Slot limits vary from water to water depending on what local officials believe would produce

9996-408: The hook and help casting the line to a further distance. The method can be used both with handlining and rod fishing, and can be done both from boats and from the land . Specialized fishing rods called "donkas" are also commonly used for bottom fishing, and a quiver tip (sometimes coupled with a jingle bell ) is used instead as the bite indicator. Some sinkers are replaced by feeders , which

10115-409: The hook to pierce internally into the fish's mouth; while snagging uses very large, sharp, multi-pointed grappling hooks that actively "claw" and pierce externally into the body/gill of the fish, and hardly ever involves any hookbait. Snagging also inflicts far more mutilating injuries to the fish and makes it very difficult to heal and survive even if the fish is released alive or manages to escape

10234-410: The hookbait. It is also not uncommon for the angler to scatter some loose bait ( groundbait ) around the target area before even casting the hook, to better attract distant fish with scents. If a fish has succumbed to its own feeding instinct and swallowed the baited hook (i.e. "bite" or "strike"), the hook point will likely pierce into and anchor itself inside the fish jaw , gullet or gill , and

10353-580: The hydroelectric reservoirs there do emit greenhouse gases, it is on a much smaller scale than thermal power plants of similar capacity. Hydropower typically emits 35 to 70 times less greenhouse gases per TWh of electricity than thermal power plants. A decrease in air pollution occurs when a dam is used in place of thermal power generation, since electricity produced from hydroelectric generation does not give rise to any flue gas emissions from fossil fuel combustion (including sulfur dioxide , nitric oxide and carbon monoxide from coal ). Dams can produce

10472-449: The lake water level fluctuates over a range of about 27 feet (8.2 m). In order to maintain dissolved oxygen concentrations in the river below the dam at levels that will support aquatic life, perforated hoses suspended above the bottom of Cherokee Reservoir are used to inject oxygen into the reservoir water and devices which resemble large underwater fans located just above the dam are used to push warm oxygenated water downward to

10591-432: The landscape is relatively flat. Other service reservoirs can be storage pools, water tanks or sometimes entirely underground cisterns , especially in more hilly or mountainous country. Modern reserviors will often use geomembrane liners on their base to limit seepage and/or as floating covers to limit evaporation, particularly in arid climates. In the United Kingdom, Thames Water has many underground reservoirs built in

10710-399: The lay of the line. When the game would swallow the bait, a tug on the line would cause the gorge to orient itself at right angles to the line, thereby sticking in the fish or animal's throat or gullet . Gorges evolved into the modern fishing hook which is J-shaped with a loop on one end and a sharp point on the other. Most hooks have a barb near the point to better anchor the point and prevent

10829-690: The line taut while fighting fish, using recurved point or "triple grip" style hooks on lures, and equipping lures that do not have them with split rings can significantly reduce escapement. Angling is also practiced in fishing tournaments, where contestants compete for prizes based on the total length or weight of a fish, usually of a pre-determined species, caught within a specified time. These contests originated as local fishing contests and have evolved to include large competitive circuits, with professional anglers that are supported by commercial endorsements. Professional anglers may gain cash prizes for placing well in tournaments. Similar competitive fishing exists at

10948-401: The line. A bite indicator is any device that can help to notify the angler that the hook has been swallowed by a fish. There are many types of bite indicators, the oldest and most ubiquitously used being the fishing float , a lightweight marker buoy that floats at the water surface with the hook and bait suspended below it. When the fish swallows the hook, the leader line between the hook and

11067-401: The lure afar and then methodically retrieves the line, pulling the lure through the water and creating vibrations, turbulent splashes and/or a popping action in the process, which imitating a small aquatic prey such as a baitfish , a drowning insect or a frog. A skilled angler can explore many possible hiding spots for fish through lure casting such as under logs and on flats. No bite indicator

11186-470: The modern use of rolled clay. The water stored in such reservoirs may stay there for several months, during which time normal biological processes may substantially reduce many contaminants and reduce turbidity . The use of bank-side reservoirs also allows water abstraction to be stopped for some time, for instance when the river is unacceptably polluted or when flow conditions are very low due to drought . The London water supply system exhibits one example of

11305-407: The mouth (i.e. snagging , or "foul hooking" and "jagging" ) or the use of nets and hand hooks other than as an aid in landing a captured fish. Some species, such as bait fish , may be taken with nets, and a few for food. Sometimes, non-sport fish are considered of lesser value and it may be permissible to take them by methods like snagging, bow and arrow or spearing , none of which fall under

11424-415: The operating rules may be complex. Most modern reservoirs have a specially designed draw-off tower that can discharge water from the reservoir at different levels, both to access water as the water level falls, and to allow water of a specific quality to be discharged into the downstream river as "compensation water": the operators of many upland or in-river reservoirs have obligations to release water into

11543-577: The person pulling it along the beach, and is pulled back to the shore intermittently to check for catches. It is also called subid-subid , sibid-sibid , paguyod , pahinas , hilada, or saliwsiw , among other names, in other Philippine languages . Laws and regulations managing angling vary greatly, often regionally, within countries. These commonly include permits (licences), closed periods (seasons) where specific species are unavailable for harvest, restrictions on gear types, and quotas . Laws generally prohibit catching fish with hooks other than in

11662-610: The popular freshwater fish species include bass , northern pike / muskellunge , walleye , trout and anadromous salmon , tilapia , channel catfish and panfishes such as crappie , sunfish (e.g. bluegill ) and yellow perch . In Europe, Asia and Australasia , freshwater anglers often pursue species such as carp , pike , bream , tench , rudd , roach , European perch , catfish and barbel , many of which are regarded as undesirable " rough fish " in North America. In developed countries , catch and release angling

11781-485: The population. For species such as marlin, muskellunge, and bass, there is a cultural taboo among anglers against taking them for food. In many parts of the world, size limits apply to certain species, meaning fish below a certain size must, by law, be released. It is generally believed that larger fish have a greater breeding potential. Some fisheries have a slot limit that allows the taking of smaller and larger fish, but requiring that intermediate sized fish be released. It

11900-481: The pre-flooded landscape, noting that forest lands, wetlands, and preexisting water features all released differing amounts of carbon dioxide and methane both pre- and post-flooding. The Tucuruí Dam in Brazil (completed in 1984) had only 0.4 times the impact on global warming than would generating the same power from fossil fuels. A two-year study of carbon dioxide and methane releases in Canada concluded that while

12019-414: The process. During the line retrieval, the angler will carefully monitor the line and rod tension to avoid equipment breaking. With stronger and feistier fish, the angler might need to temporarily halt or even reverse the line retrieval to prolong the struggle time and tire out the fish (i.e. "walking" the fish), before dragging it near enough to eventually lift it out of the water (known as " landing ") for

12138-437: The quality of the water and the ecology of the surrounding area. Many reservoirs now support and encourage less formal and less structured recreation such as natural history , bird watching , landscape painting , walking and hiking , and often provide information boards and interpretation material to encourage responsible use. Water falling as rain upstream of the reservoir, together with any groundwater emerging as springs,

12257-638: The reservoir prior to, and during, the storm. If done with sufficient lead time, the major storm will not fill the reservoir and areas downstream will not experience damaging flows. Accurate weather forecasts are essential so that dam operators can correctly plan drawdowns prior to a high rainfall event. Dam operators blamed a faulty weather forecast on the 2010–2011 Queensland floods . Examples of highly managed reservoirs are Burrendong Dam in Australia and Bala Lake ( Llyn Tegid ) in North Wales . Bala Lake

12376-459: The reservoir was the location of the 2020 Bassmaster Eastern Open tournament . Reservoir A reservoir ( / ˈ r ɛ z ər v w ɑːr / ; from French réservoir [ʁezɛʁvwaʁ] ) is an enlarged lake behind a dam , usually built to store fresh water , often doubling for hydroelectric power generation . Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting

12495-1189: The risk of transmitting Myxobolus cerebralis (whirling disease), trout and salmon should not be used as bait. Anglers may increase the possibility of contamination by emptying bait buckets into fishing venues and collecting or using bait improperly. The transportation of fish from one location to another can break the law and cause the introduction of fish alien to the ecosystem. Artificial baits are edible baits that are not directly acquired via natural means, but are made from other food materials via some kind of artificial processing. These can be fish food that are either homemade (e.g. dried food paste ) or commercially purchased (e.g. boilies and feed pellets ), or prepared/processed food such as cutlets , offals , dehulled kernels (e.g. peas and corns), dairy products (cheese and curd ), bread or doughballs made from various ingredient mixtures (e.g. rice, semolina , cornmeal , bread crumbs, and fishmeal , etc.), which can be used to attract omnivorous or even herbivorous fish. In lakes in southern climates such as Florida, panfish such as sunfish will even take household wheat bread or pet food as bait. These bread bait

12614-407: The rod fixated to the gunwale . It can also be done by very slowly winding the line in (like "finesse"-type lure fishing) or even sweeping the line sideways, with the angler operating the rod from a static position (e.g. atop a jetty, pier or bridge). A variation of trolling is drift fishing , which is usually done from an unpowered boat in faster-flowing waters. The line is not actively reeled, and

12733-519: The site where the town was originally settled. Of the 195 to 200 families who lived at the original site of Bean Station, 140 were mandated to move by the TVA. Because of the historical significance, size and potential relocation problems presented with Bean Station, officials from the TVA, the Tennessee state government, and concerned community members gathered to discuss the future of the town and its relocation efforts in 1941. A planning commission from

12852-488: The snag. The use of the hook in angling is descended, historically, from what would today be called a gorge . The word "gorge", in this context, comes from the French word meaning "throat". Gorges were used by ancient peoples to capture fish and animals like seal, walrus and birds. A gorge was a long, thin piece of bone or stone attached by its midpoint to a thin line. The gorge would be baited so that it would rest parallel to

12971-436: The spread of zebra mussels , which are known to attach themselves onto crayfish, in various waterways throughout Europe and North America. The capture, transportation and culture of bait fish can spread damaging organisms between ecosystems , endangering them. In 2007 several American states enacted regulations designed to slow the spread of fish diseases, including viral hemorrhagic septicemia , by bait fish. Because of

13090-489: The state government and TVA personnel developed plans for sites for Bean Station to relocate to as a community. After controversy arose from negotiations from unwilling property owners, and reluctance from citizens to relocate as a town, the planned community relocation project was abandoned, having Bean Stationers relocating on their own will. The reservoir was would be filled after the construction of Cherokee Dam near Grainger-Jefferson border in 1942. The dam, operated by

13209-415: The surface at both ends of the longline, with hooked snood lines hanging vertically down along the main line. Trotlines are used for catching crabs or fish (e.g. catfish ), particularly across rivers. They can be physically set in many ways, such as tying each end to a fixed structure and span the line across the water in-between like a boom , and adjusting rest of the line with weights and floats. Slabbing

13328-408: The target fish's natural diet, which are usually animals at a lower trophic level in the food web . A natural bait angler, with few exceptions, will use a common prey species of the target fish as a bait. The natural bait used may be live food (known as a live bait ) or carcass (i.e. dead bait ), and a bait improvised from grossly intact portions of a dead animal (e.g. fish head ) is known as

13447-587: The temples of Abu Simbel (which were moved before the construction of the Aswan Dam to create Lake Nasser from the Nile in Egypt ), the relocation of the village of Capel Celyn during the construction of Llyn Celyn , and the relocation of Borgo San Pietro of Petrella Salto during the construction of Lake Salto . Construction of a dammed reservoir will usually require the river to be diverted during part of

13566-511: The use of a snare trap by hunters . Longlining is a commercial fishing technique that uses a long heavy line with a series of hundreds or even thousands of baited hooks hanging from the main line via branch lines called snoods . Longlines are usually operated from specialised boats called longliners , which use a special winch to haul in the line and can operate in deeper waters targeting pelagic species such as swordfish , tuna , halibut and sablefish . Droplining involves setting

13685-499: The use of bank-side storage: here water is taken from the River Thames and River Lee into several large Thames-side reservoirs, such as Queen Mary Reservoir that can be seen along the approach to London Heathrow Airport . Service reservoirs store fully treated potable water close to the point of distribution. Many service reservoirs are constructed as water towers , often as elevated structures on concrete pillars where

13804-407: The user's rod and reel actions to successfully attract fish, and requires frequent casting and retrieving the line, and are thus more interactive and exciting. Lures can be broadly categorized into hard-body and soft-body lures , although hybrid lures with both hard and soft components are also common. Soft-body lures tend to give a more flexible and realistic "swimming" posture when towed through

13923-412: The water, which tends to partition some elements such as manganese and phosphorus into deep, cold anoxic water during the summer months. In the autumn and winter the lake becomes fully mixed again. During drought conditions, it is sometimes necessary to draw down the cold bottom water, and the elevated levels of manganese in particular can cause problems in water treatment plants. In 2005, about 25% of

14042-502: The water, while hard-body lures usually rely on stirring up more noise and turbulences . Some newer hard lure designs, however, are multi-jointed and can resemble soft lures in dynamics. Soft lures are typically coupled with a single conventional fish hook or a jighead , while hard lures commonly have more than one hooks (which are often treble hooks ). When lures are used in combination with other terminal tackles ( floats , sinkers , swivels , etc.) to produce sophisticated presentations,

14161-476: The world's 33,105 large dams (over 15 metres in height) were used for hydroelectricity. The U.S. produces 3% of its electricity from 80,000 dams of all sizes. An initiative is underway to retrofit more dams as a good use of existing infrastructure to provide many smaller communities with a reliable source of energy. A reservoir generating hydroelectricity includes turbines connected to the retained water body by large-diameter pipes. These generating sets may be at
