Willapa Bay Geographic Response Plan (WB-GRP)


Willapa Bay is a 100 square-mile estuary situated along the southern coast of Washington and is one of the most important estuaries on the West Coast. The bay has an ideal oyster growing habitat, and supports a wide diversity of wildlife.

Willapa Bay is considered to be one of the most productive bays along the Pacific. Salmon, bottom fish, oysters, crabs, clams, and shrimp are harvested from bay waters. The bay features mud and gravel beaches and saltgrass shores interspersed with wetlands and tidal flats. 20,000 acres of the bay has been set aside as a National Wildlife Refuge for habitat protection.

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
