Your PUD

Under the terms of its federal license, Chelan County PUD shall make a reasonable effort to comply with the lake level management practices defined in the Lake Level Plan in Settlement Agreement License Article 405.

Actual lake elevations may vary significantly from expected averages during drawdown and refill periods. Many factors affect lake level including precipitation, temperature, snowpack conditions, and the amount and timing of spring runoff, as well as compliance with the hydro project’s federal operating license and environmental objectives. In addition, there is the goal to meet target lake elevations May through October.

Generation is expected to be scheduled at maximum output from now through at least December.  The operational goal is to draft Lake Chelan this fall, creating storage room for runoff from potentially large fall precipitation events and spring runoff.  Historically the lake elevation has dropped approximately 1” per day
