Lake Koshkonong is a reservoir in southern Wisconsin , which was transformed from its original marshland by the construction of the Indianford Dam in 1932. The lake lies along the Rock River , with the river acting as both the primary inflow and the primary outflow for the lake. Lake Koshkonong begins 5.5 mi (8.9 km) downriver from Fort Atkinson , with the large majority of the lake located in southwestern Jefferson County . Small portions of the lake extend into southeastern Dane and northern Rock counties .
50-555: After the creation of the Indianford Dam, which was built several miles down the Rock River from Lake Koshkonong, the lake gained a surface area measuring 10,460 acres (42.3 km). It remains very shallow with an average depth of six feet (1.8 meters) and a maximum depth of seven feet (2.1 meters). The dam itself measures 13 feet (4.0 meters) high and with a length of 500 ft (150 m) at its crest. Maximum capacity of
100-428: A clear Democratic majority. After much debate, the convention produced a constitution, but the state's residents considered the document to be too radical and voted it down in a referendum, despite public campaigns for the constitution led by Doty and other delegates. A second convention called in late 1847 produced a constitution that was accepted by the people, and this enabled Wisconsin to achieve statehood in 1848. Doty
150-506: A judge, Doty served as a member of the Michigan Territorial Council from 1834 to 1835, representing the western part of the territory. In this capacity Doty argued for the creation of a new territorial government for Wisconsin, sending petitions to Congress in favor of splitting Michigan Territory into two parts, one east and one west of Lake Michigan . Doty had supported this idea as early as 1824, and argued that
200-466: A maximum depth of 7 feet, but you can still boat , canoe , and kayak here. Events hosted on the lake range from boat races to Venetian Boat Parades . Thunder on the Lake is a high speed boat race that has been held on Lake Koshkonong. The boats are hydroplane powered and can reach speeds up to 60 MPH. Other boat races are also held for fishing boats , and other smaller boats. The Venetian Boat Parade
250-692: A nuclear station in Wisconsin following the Three Mile Island accident in Pennsylvania. The plant was planned to be built on Vickerman Road, east of the lake and east of Wisconsin Highway 26 .( 42°51′37″N 88°53′27″W / 42.86028°N 88.89083°W / 42.86028; -88.89083 ( Lake Koshkonong Nuclear Plant (project) ) ) James Duane Doty James Duane Doty (November 5, 1799 – June 13, 1865)
300-418: A visibility depth of less than 3 feet. The Trophic State Index scale also helps with these classifications. If a lake scores a TSI of above 50 it will be considered hypereutrophic. Lake Koshkonong has a TSI score of 67. Algal blooms can result in high levels of blue-green algae which can be harmful to humans and pets under certain circumstances. Blue-green algae has been found in parts of Lake Koshkonong. It
350-540: Is a small tern generally found in or near inland water that breeds in Europe , Western Asia and North America . In winter the birds migrate to coastal areas of Africa and South America. The black tern was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Sterna nigra . Linnaeus specified the type location as Europe but it
400-734: Is advised by the Rock County Public Health Department to not swim in areas with floating green scum, and blue or white paint looking areas that resemble pea soup . In the 1970s, Lake Koshkonong was the primary site considered for a billion dollar nuclear power station. Wisconsin Electric Power Company , Wisconsin Power and Light Company, Madison Gas and Electric , and Wisconsin Public Service Corporation jointly proposed
450-571: Is closed in by fog." Current thinking suggests that the modern spelling is a contraction of various names given to the region by white settlers in the early 19th century. They incorporated various pronunciations of the region from various surrounding tribes, including "Kashkawanung" from the Ojibwe , "Coscahoenah" from the Menomini , and "Kuskouonog" from the Potowatomi . This theory is supported by
500-545: Is distinguishable from the European form in all plumages, and is considered by some to be a separate species. In flight, the build appears slim. The wing-beats are full and dynamic, and flight is often erratic as it dives to the surface for food; similar to other tern species. Its call has been described as a high-pitched "kik"; the sound of a large flock has been called "deafening". Hybridisation between this species and white-winged tern has been recorded from Sweden and
550-560: Is estimated to have lost over 100 acres of wetland by 2000. Now, the large pool of water known as Lake Koshkonong has been replaced by lake sedge ( Carex lacustris ), bur-reed ( Sparganium ), and other aquatic species. The lake association has been trying to introduce Pondweed and Wild celery to improve fish habitats. Throughout the Rock River (Mississippi River tributary) and Lake Koshkonong around sixty species of fish can be found. Many of those species are river spawners, meaning
SECTION 10
#1732773367183600-472: Is known for its tinted green color which is caused by algae and nutrient runoff from the Rock River . The lake is classified as hypereutrophic because it is extremely rich in nutrients and the water is shallow. The transparency of the water is low and algal blooms occur frequently, causing this classification. A lake will be classified as hypereutophic if it has more than 40 micrograms/liter of chlorophyll , more than 100 micrograms/liter of phosphorus , and
650-504: Is mostly a short term fix where human made rock formations are placed along the shoreline to protect against scour and waves . In 2002 and 2003 the Rock Koshkonong Lake District (RKLD) teamed up with wetland owners to protect around 40% or almost 5 miles of the shoreline with riprap armor. Incorporating breakwater structures has also been talked about as a potential fix to the erosion problem. Lake koshkonong
700-640: Is now restricted to Uppsala in Sweden. The black tern is now one of four species placed in the genus Chlidonias that was introduced in 1822 by the French naturalist Constantine Rafinesque . The genus name is from Ancient Greek khelidonios , "swallow-like", from khelidon , " swallow ": another old English name for the black tern is "carr (i.e. lake) swallow". The species name is from Latin niger "shining black". As its name suggests, it has predominantly dark plumage. In some lights it can appear blue in
750-556: Is put on by the Rock Koshkonong Business Association. Participants are encouraged to dress up their boat with lights and decorations of their choosing and cruise along with one another ending at the Lakeview bar. Ice fishing and ice racing used to be much more common, but due to warmer weather in the past few years the activity has not been as popular. Other winter activities practiced on and around
800-583: The Cerulean warbler and the Acadian flycatcher . Other rare species of birds that are being affected are Black tern , Forster's tern , American bittern , Least bittern , and Virginia rail . Lake Koshkonong is well known for its great fishing seasons. Hook and line fishing is open all year round with restrictions on some species including Muskellunge , Lake Sturgeon , Trout , Paddlefish , and other endangered species. Muskellunge and Hybrid season for 2020
850-449: The Town of Sumner on its northern side. Lake Koshkonong has seen many vegetational changes in the past 150 years. Once a deep-water marsh covered with emergent vegetation, the lake was predominantly wetlands filled with reeds , wild rice , and grasses. The wetlands have significantly disappeared since then due to rising water levels caused by higher dams and the ever changing landscape. It
900-632: The English population by about 1840. Intermittent attempts by the black tern to recolonise England have proved unsuccessful, with only a handful of English breeding records, and one in Ireland, in the second half of the twentieth century. North American black terns migrate to the coasts of northern South America , some to the open ocean. Old World birds winter in Africa . Unlike the "white" Sterna terns, these birds do not dive for fish, but forage on
950-523: The Governor of Michigan Territory created a separate legislature to govern the western part of the territory as Michigan prepared for statehood. In 1835, Doty campaigned to represent western Michigan Territory as a delegate in Congress, but he lost in a three-way election to George Wallace Jones . Both Doty and Jones were running as Democrats , but Doty had little true loyalty to any political party. He
1000-634: The Lowville Academy several miles north of Martinsburg in Lowville, New York . In 1818, Doty moved to Detroit , the capital of Michigan Territory , where he became an apprentice to Charles Larned , the attorney general. On November 20, 1818, he was admitted to the bar in Wayne County and Michigan Territory. He practiced law until September 29, 1819, when he was appointed clerk of court for Michigan Territory. In June 1820 he resigned
1050-557: The Netherlands. Two juvenile birds at Chew Valley Lake , England , in September 1978 and September 1981, were also believed to be hybrids; they showed mixed characters of the two species, specifically a combination of a dark mantle (a feature of white-winged black) with dark patches on the breast-side (a feature of black tern, not shown by white-winged black). Their breeding habitat is freshwater marshes across most of Canada ,
SECTION 20
#17327733671831100-541: The area codified this interpretation in the 1830s and 40's. Fort Koshkonong , a fort of some importance to the United States during the Black Hawk War , was named in accordance with this convention. The fort was active before the Rock River was dammed, when the area was a cattail marsh with the Rock River running through the middle. Today, the lake borders the Town of Koshkonong on its eastern side, and
1150-422: The breeding season, hence the old English name "blue darr". Two subspecies are recognised. These are listed below with their breeding ranges. Adults are 25 cm (10 in) long, with a wingspan 61 cm (24 in), and weigh 62 g ( 2 + 1 ⁄ 8 oz). They have short dark legs and a short, weak-looking black bill, measuring 27 mm ( 1 + 1 ⁄ 16 in), nearly as long as
1200-529: The clerkship in order to serve as secretary to the Lewis Cass expedition , a summer-long exploration of the part of Michigan Territory lying west of Lake Michigan as far as the headwaters of the Mississippi River . Upon his return to Detroit, Doty resumed his legal practice. In the winter of 1822 Doty traveled to Washington, D.C. , where on March 13, with the sponsorship of Henry Wheaton , he
1250-488: The dissatisfaction of many legislators towards the facilities at Belmont made it likely that the capital would be moved. Doty used numerous tactics to ensure that Madison would be made the capital city, wooing legislators with plans for canals and railroads and offering legislators who voted to make Madison the capital choice lots in the new city. Madison was declared the permanent capital in November, 1836, and construction at
1300-594: The east end of the island, is located in Doty Park on the southeastern riverfront of Doty Island (on the island's Neenah side). It is listed on the National Register of Historic Places . In 1861, Doty returned to public service when Republican President Abraham Lincoln appointed him to the position of Superintendent of Indian Affairs for Utah Territory . Doty was successful in this position. In 1863, Stephen Selwyn Harding , Utah's territorial governor,
1350-450: The eye, and a broadish white collar in juveniles. There are greyish-brown smudges on the ides of the white breast, a downwards extension of the plumage of the upperparts. These marks vary in size and are not conspicuous. In non-breeding plumage, most of the black, apart from the cap, is replaced by grey. The plumage of the upperparts is drab, with pale feather-edgings. The rump is brownish-grey. The North American race, C. n. surinamensis ,
1400-415: The fact that these name forms seem to share Algonquian language patterns, despite describing a Winnebago ( Siouan ) village. More evidence disputing the older name translation is that the name seems to have described a Winnebago village on the shores of the lake, with the name being extended to the body of water at a later date. This spelling of the lake's name gained legitimacy after surveying efforts in
1450-638: The governorship of the Wisconsin Territory despite Doty's status as a Democrat. Harrison died before he could make the appointment, but vice president John Tyler fulfilled Harrison's desire after ascending to the presidency in 1841. Doty was largely unsuccessful as territorial governor; the Dodge supporters in the territorial legislature rejected most of the legislation Doty supported, and Doty failed on four separate occasions to get public support for Wisconsin statehood. Doty's term ended in 1844, and he
1500-559: The growing number of residents in Wisconsin were not adequately provided for by the territorial government in Detroit, which was hundreds of miles away from any settlement in Wisconsin. Doty claimed that votes sent by residents west of Lake Michigan could not be sent to Detroit in time to be counted, and that the residents in Lower Michigan cared little about the affairs west of the lake. In 1835, his wishes were partially granted when
1550-408: The head. The bill is long, slender, and looks slightly decurved. They have a dark grey back, with a white forewing, black head, neck (occasionally suffused with grey in the adult) and belly, black or blackish-brown cap (which unites in color with the ear coverts, forming an almost complete hood), and a light brownish-grey, 'square' tail. The face is white. There is a big dark triangular patch in front of

1600-417: The lake include snowmobiling , fatbike riding , and ice skating . The loss of aquatic plant biodiversity and rising water levels on the lake due to flooding has caused significant erosion over the past 50 years. The shoreline has been impacted greatly by such events, and projects to reverse and prevent more damage from occurring have been done. Riprap armor has been used to prevent future erosion, but it
1650-479: The new city began in 1837. In 1838, Doty was elected as the Wisconsin Territory's congressional delegate, defeating George W. Jones in a rematch of the 1835 election. Despite being elected as a Democrat, Doty formed personal friendships with several Whigs in Washington, D.C., including Henry Clay . In 1840, Whig Party candidate William Henry Harrison was elected president, and he made plans to appoint Doty to
1700-626: The northern United States and much of Europe and western Asia . They usually nest either on floating material in a marsh or on the ground very close to water, laying 2–4 eggs. In England the black tern was abundant in the eastern Fens , especially in Lincolnshire and Cambridgeshire , until the early nineteenth century. The Welsh naturalist Thomas Pennant , describing a visit made to Lincolnshire in 1769, referred to 'vast flocks' of black terns that 'almost deafen one with their clamors'. Extensive drainage of its breeding grounds wiped out
1750-821: The outbreak of Utah's Black Hawk War . He was buried at the Fort Douglas Cemetery in Salt Lake City , Utah. Both the community of Dotyville, Wisconsin and town of Doty, Wisconsin were named in his honor. Doty Street in Madison is named after him. Doty Island , divided by the cities of Neenah and Menasha ; and James Island in Menasha are named after him. In addition, Doty Park in Neenah takes his name. Black tern Sterna nigra Linnaeus, 1758 The black tern ( Chlidonias niger )
1800-517: The post. With no public title, Doty worked to improve his land holdings in what would become the city of Madison. Doty had this land surveyed and platted, and made plans to create a city on the isthmus between lakes Mendota and Monona. To gain recognition for the planned city, Doty lobbied the new territorial legislature to select his proposed city as the capital of Wisconsin. A temporary capital had already been established at Belmont, Wisconsin , but its distance from Milwaukee and Green Bay coupled with
1850-514: The project. They chose Lake Koshkonong out of 84 potential sites because of the solid rock found here that could be used for the foundation, and the Rock River could be used as an adequate water source. In 1974, it was estimated that the utilities would lose $ 40 million if the two-unit, 900 MW each, facility was not approved. At that time, the timetable had already slipped to a 1983/1984 commissioning. The proposed two pressurized-water reactor system had hopes of beginning construction in 1978. The plan
1900-416: The release of gametes from the body occurs in the rivers even though they might spend their whole life in lakes. Floods and droughts will both affect spawning of different species of fish, enhancing the amount of some and depleting others. Here are a few species of fish that can be found in the lake. Muskellunge , Panfish , Largemouth bass , Smallmouth bass , Northern pike , Walleye , and Catfish . In
1950-399: The reservoir is 107,000 acre⋅ft (132,000,000 m). Both dam and reservoir are owned and operated by Rock County. The currently accepted spelling "Koshkonong" was first used by Doty in 1844. An often repeated claim that has been recently disputed is that the meaning of the name is "the lake that we live on." A more accurate approximation may be "where there is heavy fog," or "where it
2000-407: The surrounding habitats of Lake Koshkonong's riparian wetlands , many endangered species of birds can be found. The rising water levels have an unfortunate impact on these species. Loss of trees, herbaceous vegetation , and groundwater dependent wetland plants will effect the species they support. Some of the rare species found in this area that are impacted by rising water levels and habitat loss are
2050-460: Was a land speculator and politician in the United States who played an important role in the development of Wisconsin and Utah Territory . A descendant of Mayflower immigrant Edward Doty , Doty was born in Salem, New York , in 1799. He was less than three years old when his family moved to Martinsburg, New York , which was founded by his mother's brother General Walter Martin . Doty attended

2100-594: Was admitted to practice before the Supreme Court of the United States . In 1823, a new federal judicial district was created for northern and western Michigan Territory, covering what is now the state of Wisconsin and the Upper Peninsula of Michigan . Doty was appointed as the federal judge for the district by President James Monroe . Before taking up his new duties, on April 14, 1823, Doty married Sarah Collins at Whitesboro, New York . Because he
2150-553: Was conservative in view and usually aligned himself with whichever people were most popular at any given time. After losing the election, Doty turned to land speculation and bought thousands of acres of land across the region, some of which he began developing into the city of Madison, Wisconsin . In 1836, Wisconsin Territory was officially created. Doty hoped to be the territorial governor, but President Andrew Jackson appointed Henry Dodge , Doty's longtime political rival, to
2200-557: Was elected to the United States House of Representatives shortly after Wisconsin became a state, and served from 1849 to 1853 as the representative of Wisconsin's newly created 3rd congressional district and served as part of the 31st and 32nd Congresses . He was replaced by John B. Macy . After leaving Congress, Doty left public life and retired to his home on an island (now named Doty Island ) between Neenah and Menasha, Wisconsin . His log-cabin home, relocated from
2250-402: Was estimated that the disruption to farmland would cost farmers a total of $ 27,500 each year for lost crops . The Koshkonong Alert Group was an anti-nuclear group that formed in opposition of the power plant. Attempts were made to salvage the $ 40 million investment by moving the facility to Haven, Wisconsin , near Sheboygan , but state utilities gave up on their plans for construction of
2300-430: Was met with strong resistance from environmental groups. It was eventually killed in 1977 by concerns regarding the lake's shallow depth and consequences to the plant during drought conditions . Water would have been exiting the lake to cool down the plant, and residents were uneasy about that along with other aspects of the project. The power plant was intended to relocate many residents and disrupt farmland as well. It
2350-562: Was not reappointed by Tyler, who instead selected Nathaniel P. Tallmadge to the post. This left Doty to once again return to his private life. In 1846, Doty returned to politics, this time as a delegate to the First Wisconsin Constitutional Convention. Doty came to the convention as an independent, but sided with the Whigs on most issues and emerged as the opposition leader at the convention, which had
2400-649: Was open May 2, 2020 to December 31, 2020 with a minimum length limit of 40 inches and a daily bag limit of 1. For fishing to be able to occur on the lake it has to be stocked by the Wisconsin Department of Natural Resources at the Bark River Hatchery in Fort Atkinson with Walleye and Northern pike . There are four boat landings around the lake for people to use and also two beaches. The Lake is very shallow averaging around 6 feet with
2450-518: Was removed from office after public backlash from his criticism of the LDS Church and the practice of polygamy . Lincoln appointed Doty to the governorship shortly thereafter. As governor, Doty was able to repair the relationship between the federal government and the territory's Mormons . Doty also promoted the construction of schools and negotiations with local Native American tribes. Doty died in office at age 65 on June 13, 1865, shortly after
2500-440: Was required to live within his district, Doty and his new wife moved from Detroit to Prairie du Chien in 1823. Doty regularly held court at Prairie du Chien, Green Bay , and Mackinac . He also served as the first postmaster of Prairie du Chien from 1823 to 1824. In 1824, Doty moved to Green Bay, where he lived until 1841. Doty remained the district judge until he was replaced by David Irvin in 1832. Following his career as
