Public clam, mussel, and oyster beaches

Clam, mussel and oyster harvesting seasons vary by beach. For at-a-glance, site-specific harvest seasons, please see the 2020 Puget Sound clam, mussel, and oyster season guide.

Current water quality information, beach locations, harvest seasons, and health advisories can be found by searching for the beach name in the search tool on this page, or by visiting the Department of Health's (DOH) shellfish safety interactive map. Identical information is found on WDFW beach pages and the shellfish safety map, but it may be easier to search geographic areas of interest using the map tool. The shellfish safety map also provides links to the detailed WDFW page for each beach.  

A list of the tides in the Puget Sound region that favor good harvest results can be found in the 2020 best clam and oyster harvest tides chart. 

For help identifying clam, mussel and oyster (bivalve) species, download the shellfish identification chart.

WDFW works closely with DOH to ensure safe, legal harvest of shellfish on state beaches. In order to safely harvest shellfish for human consumption, both the DOH health status and the WDFW season for a beach must be open.

DOH status WDFW season Harvest status
Open Open Safe and legal
Open Closed Illegal
Closed Open Not safe
