Olympic National Park protects over 75 miles of Pacific Coast, 600 lakes, and 4,000 miles of rivers and streams that support some of the most extensive runs of wild salmon, trout, and char remaining in the Pacific Northwest. Through the management of fish and aquatic environments, the park works to preserve and restore native fishes and their habitats and provide recreational fishing opportunities for the enjoyment of park visitors. Fisheries biologists work with the State of Washington and eight treaty tribes each year to establish harvest and gear regulations.
