The lake is 9 miles end to end, and between 1 and 3 miles wide. Over 90% of the water comes from the rain and is very clear. You can see the bottom at 20 feet when calm. The reason it is so clean is because of the ratio of surface area to runoff. Lake Geneva it is 4:2, most lakes in Wisconsin the ratio is 40 to 60:1, like Lake Delavan or Lake Como, yuck!
The spring kayaking season is roaring down the White River outside Lake Geneva this year, with the resent heavy rains, the river is really ripping. The launching place most of the local kayaks take off from is on Sheridan Springs Road in the Township of Lyons. Going north on Sheridan Springs Road outside of Lake Geneva from Edwards Boulevard the first two bridges are where most locals launch from.
