Admiralty Inlet/Hood Canal Geographic Response Plan (AIHC-GRP)

Hood Canal

Admiralty Inlet and Hood Canal are located in the northwest corner of Washington State. Admiralty Inlet extends from eastern Strait of Juan de Fuca to Foulweather Bluff, and Hood Canal separates the Olympic Peninsula from the Kitsap Peninsula. Local economies are based primarily on natural resource use and tourism. This plan is divided into two regions, Admiralty Inlet and Hood Canal.

Admiralty Inlet is comprised of the area north of the Hood Canal Bridge to Port Townsend. It is also a biologically rich area with several types of fisheries resources, clams and marine birds. Dall's porpoise and harbor seals also frequent the area. Salmon pass through the Inlet en route to Hood Canal and Puget Sound in early fall.

Hood Canal is bounded by Hood Canal Bridge to the north and continues southward to Belfair. The canal supports significant populations of groundfish, clams, shrimp, Dungeness Crab, as well as several other fish resources. It is also a major marine habitat for river otters and species of marine birds.

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
