Is Lake Waha low for this time of year?

Seasonal comparison matters more than the raw number, because most reservoirs draw down predictably through late summer and refill over winter and spring.
Why is Lake Waha 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. Lake Waha has fallen 0.63 ft over the past 30 days. For the operational reason on any given week, check the U.S. Bureau of Reclamation directly.
