Lake Koshkonong

From Wikipedia, the free encyclopedia

Lake Koshkonong is a lake in southern Wisconsin. It lies along the Rock River, 5.5 mi. down-river from Fort Atkinson, primarily in southwestern Jefferson County, although small portions of the lake extend into southeastern Dane and northern Rock counties.

Lake Koshkonong shares its name with Fort Koshkonong, a fort of some importance during the Black Hawk War. It is a manmade lake, and at the time the fort was active, before the Rock River was dammed, the area was actually a cattail marsh with the Rock River running through the middle. The Indianford Dam several miles down the Rock River from Lake Koshkonong makes it one of the larger lakes in the state of Wisconsin (10,500 acres) but it remains very shallow with an average depth of six feet.
