Lake Chelan Geographic Response Plan (LKCH-GRP)

Lake Chelan

This is a condensed GRP developed for Lake Chelan partially in response to the Holden Mine Superfund remediation project. This GRP is located in Central Washington, north of Wenatchee in the rain shadow of the Cascade Range. The area included in this plan is Lake Chelan from the city of Chelan to Lucerne Landing.

Interim Updates

In between plan updates, GRP strategies are tested during drills and actual spill events. The results of these tests may require changes to certain response strategies, notification strategies, staging areas, or boat launch locations. Eventually, these changes will be fully incorporated into the plan. Until that time, please use the updated strategy and information sheets below in lieu of that provided for similarly numbered locations in the published plan.

No interim updates currently available
