Future Operation
Refilling of Lake Chelan continues. If forecasted weather conditions occur Lake Chelan is expected to reach elevation 1,099 on Saturday, July 5. It is also expected that the lake will continue to fill through early July. The maximum lake elevation allowed under the new operating license is 1,100 feet. Generation is scheduled at maximum output of 54 MW, with occasional scheduling between 8 MW and 54 MW in order to coordinate with Columbia River operations and respond to market conditions. Spill is expected to continue for several weeks. Current Lake Level (Lakeside Gauge)
