Willapa Bay

Willapa Bay is a large estuary located on the coast of southwestern Washington State. It’s a sheltered coastal bay formed by the meeting of river waters, primarily from the Willapa River, with the Pacific Ocean. The bay covers around 160 square miles and is known for its rich mudflats, which support abundant shellfish like oysters and clams. Its productive environment also provides habitat for various fish and bird species. The bay plays a vital role in local fisheries, agriculture, and wildlife conservation, making it an important ecological and economic resource for the region.
