Is Geneva Lake low for this time of year?

Why is Geneva Lake changing right now?
Reservoir levels move for four main reasons: rainfall and runoff into the basin, releases through the dam for downstream water supply, power generation or flood control, evaporation during hot months, and seasonal drawdown schedules set by the operating agency. Geneva Lake has risen 0.09 ft over the past 30 days. For the operational reason on any given week, check the U.S. Geological Survey directly.
