About this gauge's record
This site's drainage basin covers approximately 29 sq mi of contributing watershed.
The dam behind Geneva Lake at Lake Geneva
Geneva Lake at Lake Geneva is held back by Lake Geneva (also recorded as Geneva Lake) , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 14 ft high and running 300 ft along its crest , built across WHITE RIVER in Walworth County , near LAKE GENEVA . It was completed in 1836 and modified in 1912O , and is owned by Lake Level Board (a private owner) .
Its recorded primary purpose is recreation — holding a stable pool through the season is an operating goal, so a level well off normal in summer is unusual rather than routine .
Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves.
NID classes it low hazard potential: a failure would be expected to damage little beyond the owner's own property. It is a consequence rating, not a condition rating. Its most recent condition assessment was satisfactory — no deficiencies recognised for expected loading. That assessment is dated 10/29/2019.
At its normal pool the reservoir covers about 5,262 acres. NID records a maximum storage of 40,000 acre-ft against a normal storage of 30,000 acre-ft. Its maximum discharge capacity is 650 cubic feet per second. It is regulated by WIDNR.
