Licensing and Compliance 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.

Future Operation
The elevation of Lake Chelan will continue to increase as the snows melts and flows into the lake. It is expected the lake elevation will be between 1,097.6 and 1,099.1 feet above sea level on June 20, and is likely to be between 1,098.8 and 1,099.6 feet above sea level on July 1.

Actual lake elevations may vary significantly from expected averages during drawdown and refill periods. Many factors impact lake elevations including precipitation, temperature, snowpack conditions, volume and timing of spring runoff, as well as efforts to comply with operating and environmental objectives in the Hydro Project’s License and the goal of meeting target lake elevations during May through September.

Public Boat Ramps at Lake Chelan

We are sensitive to the needs of the many users of Lake Chelan. Below are the elevations at the bottom of each concrete boat ramp. As lake levels fluctuate, boaters are asked to take these elevations into consideration before launching a boat.
