Your PUD Lake Chelan Lake Levels
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.
Lake Chelan is to remain in the top one foot of operating range through July and most of August. The next target elevation is 1099.0 feet on August 1. This target elevation is expected to be met at the current time.
