How much has Tioga Lake moved recently?

Why is Tioga Lake low 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. Tioga Lake has fallen 0.33 ft over the past 30 days. For the operational reason on any given week, check the U.S. Army Corps of Engineers directly.
