79-417: Lakes , natural forests , and wetlands provide natural habitats for many smaller species close to an urban metropolitan area . Wildlife can be observed in their natural environment from the many trails in the park. Shelby Farms park is home to a bison herd. The land Shelby Farm sits atop today was privately-owned property in the 19th century. In 1825, humanist reformer Frances Wright founded

158-534: A $ 52 million expansion that included an enlargement of Patriot Lake (renamed Hyde Lake), the addition of new walking and biking trails, the construction of a new visitors center, and the planting of more than 1 million new trees across the park. In the year after Heart of the Park opened, park staff estimated that visitation to Shelby Farms had more than doubled. James Corner Field Operations (JCFO) located in New York won

237-409: A body of water from 2 hectares (5 acres) to 8 hectares (20 acres). Pioneering animal ecologist Charles Elton regarded lakes as waterbodies of 40 hectares (99 acres) or more. The term lake is also used to describe a feature such as Lake Eyre , which is a dry basin most of the time but may become filled under seasonal conditions of heavy rainfall. In common usage, many lakes bear names ending with

316-500: A comprehensive analysis of the origin of lakes and proposed what is a widely accepted classification of lakes according to their origin. This classification recognizes 11 major lake types that are divided into 76 subtypes. The 11 major lake types are: Tectonic lakes are lakes formed by the deformation and resulting lateral and vertical movements of the Earth's crust. These movements include faulting, tilting, folding, and warping. Some of

395-402: A form of organic lake. They form where a buildup of partly decomposed plant material in a wet environment leaves the vegetated surface below the water table for a sustained period of time. They are often low in nutrients and mildly acidic, with bottom waters low in dissolved oxygen. Artificial lakes or anthropogenic lakes are large waterbodies created by human activity . They can be formed by

474-538: A higher perimeter to area ratio than other lake types. These form where sediment from a tributary blocks the main river. These form where sediment from the main river blocks a tributary, usually in the form of a levee . Lakes formed by other processes responsible for floodplain basin creation. During high floods they are flushed with river water. There are four types: 1. Confluent floodplain lake, 2. Contrafluent-confluent floodplain lake, 3. Contrafluent floodplain lake, 4. Profundal floodplain lake. A solution lake

553-510: A hypolimnion; accordingly, very shallow lakes are excluded from this classification system. Based upon their thermal stratification, lakes are classified as either holomictic , with a uniform temperature and density from top to bottom at a given time of year, or meromictic , with layers of water of different temperature and density that do not intermix. The deepest layer of water in a meromictic lake does not contain any dissolved oxygen so there are no living aerobic organisms . Consequently,

632-428: A lake consists of a large area of standing water that occupies an extensive closed depression in limestone, it is also called a karst lake . Smaller solution lakes that consist of a body of standing water in a closed depression within a karst region are known as karst ponds. Limestone caves often contain pools of standing water, which are known as underground lakes . Classic examples of solution lakes are abundant in

711-470: A large number of studies agree that small ponds are much more abundant than large lakes. For example, one widely cited study estimated that Earth has 304 million lakes and ponds, and that 91% of these are 1 hectare (2.5 acres) or less in area. Despite the overwhelming abundance of ponds, almost all of Earth's lake water is found in fewer than 100 large lakes; this is because lake volume scales superlinearly with lake area. Extraterrestrial lakes exist on

790-692: A much enlarged (and renamed) Hyde Lake, formerly known as Patriot Lake. Encompassing about 4,500 acres (1,800 ha) of land, Shelby Farms is a large urban park in the United States and one of the largest in Tennessee. It is within the area of East Memphis Several lakes, natural forests, and the wetlands of the Wolf River are situated in hilly surroundings. Wildlife , including beavers , deer , turtles , and different species of birds , can be observed in its natural environment . Although

869-489: A natural outflow and lose water solely by evaporation or underground seepage, or both. These are termed endorheic lakes. Many lakes are artificial and are constructed for hydroelectric power generation, aesthetic purposes, recreational purposes, industrial use, agricultural use, or domestic water supply . The number of lakes on Earth is undetermined because most lakes and ponds are very small and do not appear on maps or satellite imagery . Despite this uncertainty,

948-403: A result of meandering. The slow-moving river forms a sinuous shape as the outer side of bends are eroded away more rapidly than the inner side. Eventually a horseshoe bend is formed and the river cuts through the narrow neck. This new passage then forms the main passage for the river and the ends of the bend become silted up, thus forming a bow-shaped lake. Their crescent shape gives oxbow lakes

1027-535: A result of the 1959 Hebgen Lake earthquake . Most landslide lakes disappear in the first few months after formation, but a landslide dam can burst suddenly at a later stage and threaten the population downstream when the lake water drains out. In 1911, an earthquake triggered a landslide that blocked a deep valley in the Pamir Mountains region of Tajikistan , forming the Sarez Lake . The Usoi Dam at

1106-432: A term of years as indentured servants . This type of penal institution has mainly been implanted in rural regions of vast countries. For example, the following passage describes the prison system of the U.S. state of North Carolina in the early twentieth century: "The state prison is at Raleigh, although most of the convicts are distributed upon farms owned and operated by the state. The lease system does not prevail, but

1185-422: A variation in density because of thermal gradients. Stratification can also result from a density variation caused by gradients in salinity. In this case, the hypolimnion and epilimnion are separated not by a thermocline but by a halocline , which is sometimes referred to as a chemocline . Lakes are informally classified and named according to the seasonal variation in their lake level and volume. Some of

1264-443: Is sag ponds . Volcanic lakes are lakes that occupy either local depressions, e.g. craters and maars , or larger basins, e.g. calderas , created by volcanism . Crater lakes are formed in volcanic craters and calderas, which fill up with precipitation more rapidly than they empty via either evaporation, groundwater discharge, or a combination of both. Sometimes the latter are called caldera lakes, although often no distinction

1343-542: Is a 10.65-mile (17.14 km) multi-use urban rail trail running from Shelby Farms to Tillman Street in the Binghampton neighborhood, near Midtown, Memphis . The trail was constructed over a closed CSX railway line. Shelby Farms Greenline is managed and operated by Shelby Farms Park Conservancy, a nonprofit organization that also manages Shelby Farms park. The Greenline opened in October 2010. Shelby Farms Greenline

1422-403: Is a lake occupying a basin formed by surface dissolution of bedrock. In areas underlain by soluble bedrock, its solution by precipitation and percolating water commonly produce cavities. These cavities frequently collapse to form sinkholes that form part of the local karst topography . Where groundwater lies near the grounds surface, a sinkhole will be filled water as a solution lake. If such

1501-468: Is dammed behind an ice shelf that is attached to the coastline. They are mostly found in Antarctica. Fluvial (or riverine) lakes are lakes produced by running water. These lakes include plunge pool lakes , fluviatile dams and meander lakes. The most common type of fluvial lake is a crescent-shaped lake called an oxbow lake due to the distinctive curved shape. They can form in river valleys as

1580-444: Is located near the welcome center of the park. A BMX race track sanctioned by USA BMX is located at 6435 Walnut Grove Rd. Lake A lake is an often naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land . Lakes lie completely on land and are separate from the ocean , although they may be connected with

1659-452: Is made. An example is Crater Lake in Oregon , in the caldera of Mount Mazama . The caldera was created in a massive volcanic eruption that led to the subsidence of Mount Mazama around 4860 BCE. Other volcanic lakes are created when either rivers or streams are dammed by lava flows or volcanic lahars . The basin which is now Malheur Lake , Oregon was created when a lava flow dammed

1738-548: Is the longest, continuous urban trail in the Memphis area. It is also the first trail in Tennessee to use a pedestrian hybrid beacon at two major crossings: Highland and Graham. Horseback riding is allowed in parts of the park and on a few trails. Horses can be rented as well. A designated runway to start and land miniature radio-controlled aircraft is present in the park for public use. An 18-hole disc golf course

1817-429: Is unknown but is estimated to be at least 2 million. Finland has 168,000 lakes of 500 square metres (5,400 sq ft) in area, or larger, of which 57,000 are large (10,000 square metres (110,000 sq ft) or larger). Most lakes have at least one natural outflow in the form of a river or stream , which maintain a lake's average level by allowing the drainage of excess water. Some lakes do not have

1896-505: The Foulk Reformatory and Manual Training School for negro youth was provided for. Charitable and penal institutions are under the supervision of a Board of Public Charities, appointed by the governor for a period of six years, the terms of the different members expiring in different years. Private institutions for the care of the insane, idiots, feeble-minded, and inebriates may be established, but must be licensed and regulated by

1975-567: The House of Commons in Canada announced that the skills that prison farms had been giving inmates were outdated, and that prison labor should focus on work related to more modern skills. Although the Canadian prison farm system has been shut down since 2009, the debate as to whether or not the farms should reopen has continued. The group called Save our Prison Farms (SOPF) has been trying to revive

2054-759: The Malheur River . Among all lake types, volcanic crater lakes most closely approximate a circular shape. Glacial lakes are lakes created by the direct action of glaciers and continental ice sheets. A wide variety of glacial processes create enclosed basins. As a result, there are a wide variety of different types of glacial lakes and it is often difficult to define clear-cut distinctions between different types of glacial lakes and lakes influenced by other activities. The general types of glacial lakes that have been recognized are lakes in direct contact with ice, glacially carved rock basins and depressions, morainic and outwash lakes, and glacial drift basins. Glacial lakes are

2133-474: The Nashoba Commune on 670 acres north of Wolf River, now part of Shelby Farms Park and Agricenter International. Throughout the 1800s, the commune provided practical and cultural education to emancipated slaves after they worked off the costs of their indentured servitude. Remains of a settlement from the late 19th century are still present in the modern-day park. From 1929 until 1964, Shelby Farms

Cognates include Dutch laak ('lake, pond, ditch'), Middle Low German lāke ('water pooled in a riverbed, puddle') as in: de:Wolfslake , de:Butterlake , German Lache ('pool, puddle'), and Icelandic lækur ('slow flowing stream'). Also related are the English words leak and leach . There is considerable uncertainty about defining

2291-551: The United States Constitution prohibited the use of slavery and involuntary servitude but explicitly exempts those who have been convicted of a crime. In response to this, the southern state legislatures implemented " Black Codes ", which were laws that explicitly applied to African-Americans and subjected them to criminal prosecution for minor offenses like breaking curfew, loitering, and not carrying proof of employment. These new laws led to more prisoners for

2370-399: The density of water varies with temperature, with a maximum at +4 degrees Celsius, thermal stratification is an important physical characteristic of a lake that controls the fauna and flora , sedimentation, chemistry, and other aspects of individual lakes. First, the colder, denser water typically forms a layer near the bottom, which is called the hypolimnion . Second, normally overlying

2449-399: The emancipation of slaves by providing education for them in practical and cultural skills. Remains of an early settlement from the late 19th century can be found at the eastern tip of Shelby Farms park, consisting of ruins of a residential building, a disintegrated barn, car wrecks dating from the 1950s and 1960s, old fences and a family burial site. In 2005, the family burial site of

2528-493: The thirteenth amendment to the Constitution ; however, some other parts of the world have made penal labor illegal. The concepts of prison farm and labor camp overlap, with the idea that the prisoners are forced to work. The historical equivalent on a very large scale was called a penal colony . The agricultural goods produced by prison farms are generally used primarily to feed the prisoners themselves and other wards of

2607-556: The 2.75-mile (4.4 km) long Chickasaw Trail, is available to hikers. An unpaved trail, the Tour de Wolf, takes hikers and bikers through the woods of Shelby Farms Park for 6.08 miles (9.8 km). The paved trails are suitable for walking, running, biking, and roller-blading. The Tour de Wolf is suitable for walking, running, and mountain-biking. Off-leash dog activities are designated in a 120-acre (49 ha) area that includes meadows, lakes and hiking trails. The Shelby Farms Greenline

Examples of meteorite lakes are Lonar Lake in India, Lake El'gygytgyn in northeast Siberia, and the Pingualuit crater lake in Quebec, Canada. As in the cases of El'gygytgyn and Pingualuit, meteorite lakes can contain unique and scientifically valuable sedimentary deposits associated with long records of paleoclimatic changes. In addition to

In India, Sudarshana Lake is a historical artificial lake located in the semi-arid region of Girnar, Gujarat, originally constructed during the reign of Chandragupta Maurya. See: List of notable artificial lakes in the United States Meteorite lakes, also known as crater lakes (not to be confused with volcanic crater lakes ), are created by catastrophic impacts with

2844-506: The Mann family exists with just one grave marker remaining. The last two documented deaths , as indicated on that remaining gravestone , date back to November 25, 1891 for Robert W. Mann and December 5, 1891 for Mary S. Mann. Five or more graves are marked only by their base stones. Shelby County acquired 1,600 acres (650 ha) of land in 1928 for use as a penal farm. The remaining formerly private property of 2,900 acres (1,200 ha)

2923-615: The Providence county jail, the state workhouse and the house of correction, the state almshouse, the state hospital for the insane, the Sockanosset school for boys, and the Oaklawn school for girls, the last two being departments of the state reform school." There are prison farms in other countries. Canada had six prison farms, where up to 800 inmates did everything from tending pigs to milking cows, until they were closed in 2010 by

3002-538: The SFPA, forming the Shelby Farms Park Conservancy (SFPC), a public and private non-profit partnership established by Shelby County government to help provide day-to-day operations of the park and to develop a planning process for the future of Shelby Farms park. A masterplan was put in place in 2008 to direct a major re-design of the park. This came to fruition in 2016, when Shelby Farms opened

3081-509: The SFPC's competition for the park's master plan. JCFO also partnered with Marlon Blackwell Architects (MBA) to design half-dozen new buildings. Hiking and biking trails meandering through the park allow visitors to observe wildlife and nature . On two lakes rowing boats are allowed. On one of the latter two lakes, Hyde Lake, pedal boats can be rented. There is also a 2.5-mile (4.0 km) paved trail around Hyde Lake. Another paved trail,

3160-866: The base of the valley has remained in place for more than 100 years but the terrain below the lake is in danger of a catastrophic flood if the dam were to fail during a future earthquake. Tal-y-llyn Lake in north Wales is a landslide lake dating back to the last glaciation in Wales some 20000 years ago. Aeolian lakes are produced by wind action . These lakes are found mainly in arid environments, although some aeolian lakes are relict landforms indicative of arid paleoclimates . Aeolian lakes consist of lake basins dammed by wind-blown sand; interdunal lakes that lie between well-oriented sand dunes ; and deflation basins formed by wind action under previously arid paleoenvironments. Moses Lake in Washington , United States,

3239-519: The concept of penal servitude (i.e., forced and unpaid labor as a punishment for a crime). This exemption only affected those who have been convicted of crimes, not those who were still awaiting trial. Britain had a long history of penal servitude even before passage of the Penal Servitude Act of 1853, and routinely used convict labor to settle its conquests, either through penal colonies or by selling convicts to settlers to serve for

3318-915: The courses of mature rivers, where a river channel has widened over a basin formed by eroded floodplains and wetlands . Some lakes are found in caverns underground . Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice age . All lakes are temporary over long periods of time , as they will slowly fill in with sediments or spill out of the basin containing them. Artificially controlled lakes are known as reservoirs , and are usually constructed for industrial or agricultural use, for hydroelectric power generation, for supplying domestic drinking water , for ecological or recreational purposes, or for other human activities. The word lake comes from Middle English lake ('lake, pond, waterway'), from Old English lacu ('pond, pool, stream'), from Proto-Germanic * lakō ('pond, ditch, slow moving stream'), from

3397-518: The creation of lakes by the disruption of preexisting drainage networks, it also creates within arid regions endorheic basins that contain salt lakes (also called saline lakes). They form where there is no natural outlet, a high evaporation rate and the drainage surface of the water table has a higher-than-normal salt content. Examples of these salt lakes include Great Salt Lake and the Dead Sea . Another type of tectonic lake caused by faulting

3476-622: The difference between lakes and ponds , and neither term has an internationally accepted definition across scientific disciplines or political boundaries. For example, limnologists have defined lakes as water bodies that are simply a larger version of a pond, which can have wave action on the shoreline or where wind-induced turbulence plays a major role in mixing the water column. None of these definitions completely excludes ponds and all are difficult to measure. For this reason, simple size-based definitions are increasingly used to separate ponds and lakes. Definitions for lake range in minimum sizes for

3555-483: The exception of criterion 3, the others have been accepted or elaborated upon by other hydrology publications. The majority of lakes on Earth are freshwater , and most lie in the Northern Hemisphere at higher latitudes . Canada , with a deranged drainage system , has an estimated 31,752 lakes larger than 3 square kilometres (1.2 sq mi) in surface area. The total number of lakes in Canada

3634-548: The farming out of convict labor is permitted by the constitution; such labor is used chiefly for the building of railways, the convicts so employed being at all times cared for and guarded by state officials. A reformatory for white youth between the ages of seven and sixteen, under the name of the Stonewall Jackson Manual Training and Industrial School , was opened at Concord in 1909, and in March 1909

3713-482: The government generally does so at a steep discount from the cost of free labor. Louisiana State Penitentiary is the largest prison farm covering 18,000 acres (7,300 hectares); it is bordered on three sides by the Mississippi River. Canada has six large prison farms, which were closed in 2010. Beginning in 2019, two of the farms were gradually reopened. Convict leasing was a system of penal labor that

3792-422: The hypolimnion is a transition zone known as the metalimnion . Finally, overlying the metalimnion is a surface layer of warmer water with a lower density, called the epilimnion . This typical stratification sequence can vary widely, depending on the specific lake or the time of year, or a combination of both. The classification of lakes by thermal stratification presupposes lakes with sufficient depth to form

3871-907: The intentional damming of rivers and streams, rerouting of water to inundate a previously dry basin , or the deliberate filling of abandoned excavation pits by either precipitation runoff , ground water , or a combination of both. Artificial lakes may be used as storage reservoirs that provide drinking water for nearby settlements , to generate hydroelectricity , for flood management , for supplying agriculture or aquaculture , or to provide an aquatic sanctuary for parks and nature reserves . The Upper Silesian region of southern Poland contains an anthropogenic lake district consisting of more than 4,000 water bodies created by human activity. The diverse origins of these lakes include: reservoirs retained by dams, flooded mines, water bodies formed in subsidence basins and hollows, levee ponds, and residual water bodies following river regulation. Same for

3950-471: The karst regions at the Dalmatian coast of Croatia and within large parts of Florida . A landslide lake is created by the blockage of a river valley by either mudflows , rockslides , or screes . Such lakes are most common in mountainous regions. Although landslide lakes may be large and quite deep, they are typically short-lived. An example of a landslide lake is Quake Lake , which formed as

4029-412: The lake level. Prison farm A prison farm (also known as a penal farm ) is a large correctional facility where penal labor convicts are forced to work — legally or illegally — on a farm (in the wide sense of a productive unit), usually for manual labor, largely in the open air, such as in agriculture, logging, quarrying, and mining. In the United States, such forced labor is made legal by

4108-657: The largest lakes on Earth are rift lakes occupying rift valleys, e.g. Central African Rift lakes and Lake Baikal . Other well-known tectonic lakes, Caspian Sea , the Sea of Aral , and other lakes from the Pontocaspian occupy basins that have been separated from the sea by the tectonic uplift of the sea floor above the ocean level. Often, the tectonic action of crustal extension has created an alternating series of parallel grabens and horsts that form elongate basins alternating with mountain ranges. Not only does this promote

4187-528: The layers of sediment at the bottom of a meromictic lake remain relatively undisturbed, which allows for the development of lacustrine deposits . In a holomictic lake, the uniformity of temperature and density allows the lake waters to completely mix. Based upon thermal stratification and frequency of turnover, holomictic lakes are divided into amictic lakes , cold monomictic lakes , dimictic lakes , warm monomictic lakes, polymictic lakes , and oligomictic lakes. Lake stratification does not always result from

4266-560: The level of a lake are controlled by the difference between the input and output compared to the total volume of the lake. Significant input sources are precipitation onto the lake, runoff carried by streams and channels from the lake's catchment area, groundwater channels and aquifers, and artificial sources from outside the catchment area. Output sources are evaporation from the lake, surface and groundwater flows, and any extraction of lake water by humans. As climate conditions and human water requirements vary, these will create fluctuations in

4345-481: The mainland; lakes cut off from larger lakes by a bar; or lakes divided by the meeting of two spits. Organic lakes are lakes created by the actions of plants and animals. On the whole they are relatively rare in occurrence and quite small in size. In addition, they typically have ephemeral features relative to the other types of lakes. The basins in which organic lakes occur are associated with beaver dams, coral lakes, or dams formed by vegetation. Peat lakes are

4424-424: The mode of origin, lakes have been named and classified according to various other important factors such as thermal stratification , oxygen saturation, seasonal variations in lake volume and water level, salinity of the water mass, relative seasonal permanence, degree of outflow, and so on. The names used by the lay public and in the scientific community for different types of lakes are often informally derived from

4503-485: The moon Titan , which orbits the planet Saturn . The shape of lakes on Titan is very similar to those on Earth. Lakes were formerly present on the surface of Mars, but are now dry lake beds . In 1957, G. Evelyn Hutchinson published a monograph titled A Treatise on Limnology , which is regarded as a landmark discussion and classification of all major lake types, their origin, morphometric characteristics, and distribution. Hutchinson presented in his publication

4582-415: The morphology of the lakes' physical characteristics or other factors. Also, different cultures and regions of the world have their own popular nomenclature. One important method of lake classification is on the basis of thermal stratification, which has a major influence on the animal and plant life inhabiting a lake, and the fate and distribution of dissolved and suspended material in the lake. For example,

4661-406: The most numerous lakes in the world. Most lakes in northern Europe and North America have been either influenced or created by the latest, but not last, glaciation, to have covered the region. Glacial lakes include proglacial lakes , subglacial lakes , finger lakes , and epishelf lakes. Epishelf lakes are highly stratified lakes in which a layer of freshwater, derived from ice and snow melt,

4740-791: The names include: Lakes may be informally classified and named according to the general chemistry of their water mass. Using this classification method, the lake types include: A paleolake (also palaeolake ) is a lake that existed in the past when hydrological conditions were different. Quaternary paleolakes can often be identified on the basis of relict lacustrine landforms, such as relict lake plains and coastal landforms that form recognizable relict shorelines called paleoshorelines . Paleolakes can also be recognized by characteristic sedimentary deposits that accumulated in them and any fossils that might be contained in these sediments. The paleoshorelines and sedimentary deposits of paleolakes provide evidence for prehistoric hydrological changes during

4819-556: The ocean by rivers . Lakes, as with other bodies of water , are part of the water cycle , the processes by which water moves around the Earth. Most lakes are freshwater and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater . Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds , which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing

4898-562: The organic-rich deposits of pre-Quaternary paleolakes are important either for the thick deposits of oil shale and shale gas contained in them, or as source rocks of petroleum and natural gas . Although of significantly less economic importance, strata deposited along the shore of paleolakes sometimes contain coal seams . Lakes have numerous features in addition to lake type, such as drainage basin (also known as catchment area), inflow and outflow, nutrient content, dissolved oxygen , pollutants , pH , and sedimentation . Changes in

Shelby Farms park is home to a bison herd on 56 acres (23 ha) of pasture land. Former Shelby County Mayor Bill Morris was instrumental, along with park superintendent Tom Hill, in introducing the bison , which now number about 45. In 1825, Frances Wright 's Nashoba Experiment

5056-426: The penal system that could all be leased by the state so that it can use their labor for profit. Widespread convict leasing ended by World War II , but the loopholes in the 13th Amendment still permit the use of prisoners to work without pay. Convicts may also be leased for non-agricultural work, either directly to state entities, or to private industry. For example, prisoners may make license plates under contract to

5135-501: The prison farm concept, since they did not want to pay for farm labor. When active, the prison farms highlighted many inherent inequalities within Canadian society. For example, the incarceration rate of the indigenous " First Nations " people of Canada was ten times greater than that of non-aboriginal Canadians. in 2009, when the prison farm program in Canada was about to shut down, the Government of Canada gave three reasons to cut

5214-547: The program: The revenue of the six prisons was CA$ 7.5 million, while the expenses were CA$ 11.5 million, with a net loss to the government of about four million dollars on a useless program. Since the Canadian Prison Farm Program was found to not be effective, along with its inherent inequalities, it seemed to make sense to just shut it down altogether. The 13th Amendment to the United States Constitution , which ended slavery, specifically carved out

5293-477: The state department of motor vehicles , work in textile or other state-run factories, or may perform data processing for outside firms. Other types of work include food service or groundskeeping. These laborers are typically considered to be a part of prison industries and not prison farms. In 2009, Canada shut down six of its major prison farms. Canada had used its prison farms as a way to generate revenue, as well as to give prisoners skills post-release. In 2009,

In addition to being forced to labor directly for the government on a prison farm or in a penal colony, inmates may be forced to do farm work for private enterprises by being farmed out through the practice of convict leasing to work on private agricultural lands or related industries (fishing, lumbering, etc.). The party purchasing their labor from

The Shelby Farms Park Alliance (SFPA) was granted a conservation easement by the Shelby County Commission in December 2006. The easement restricts commercial and residential development in the park area for 50 years. In 2007, an agreement was signed between the Shelby County Mayor A.C. Wharton and

5609-404: The thermal stratification, as well as the degree and frequency of mixing, has a strong control over the distribution of oxygen within the lake. Professor F.-A. Forel , also referred to as the "Father of limnology", was the first scientist to classify lakes according to their thermal stratification. His system of classification was later modified and improved upon by Hutchinson and Löffler. As

5688-456: The times that they existed. There are two types of paleolake: Paleolakes are of scientific and economic importance. For example, Quaternary paleolakes in semidesert basins are important for two reasons: they played an extremely significant, if transient, role in shaping the floors and piedmonts of many basins; and their sediments contain enormous quantities of geologic and paleontologic information concerning past environments.

5767-641: The two. Lakes are also distinct from lagoons , which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large lakes. Most lakes are fed by springs , and both fed and drained by creeks and rivers , but some lakes are endorheic without any outflow, while volcanic lakes are filled directly by precipitation runoffs and do not have any inflow streams. Natural lakes are generally found in mountainous areas (i.e. alpine lakes ), dormant volcanic craters , rift zones and areas with ongoing glaciation . Other lakes are found in depressed landforms or along

5846-467: The word pond , and a lesser number of names ending with lake are, in quasi-technical fact, ponds. One textbook illustrates this point with the following: "In Newfoundland, for example, almost every lake is called a pond, whereas in Wisconsin, almost every pond is called a lake."

6083-617: Was originally a shallow natural lake and an example of a lake basin dammed by wind-blown sand. China's Badain Jaran Desert is a unique landscape of megadunes and elongated interdunal aeolian lakes, particularly concentrated in the southeastern margin of the desert. Shoreline lakes are generally lakes created by blockage of estuaries or by the uneven accretion of beach ridges by longshore and other currents. They include maritime coastal lakes, ordinarily in drowned estuaries; lakes enclosed by two tombolos or spits connecting an island to

6162-556: Was primarily practiced in the Southern United States , widely involved the use of African-American men, and was prominently used after the American Civil War .
