Rule making for 2024 seasons is underway. More information may be found on the Washington Department of Fish & Wildlife rule making webpage

Clam, mussel and oyster harvesting seasons vary by beach. For size and harvest limits, please see statewide shellfish and seaweed daily limits and shellfish size rules.

For at-a-glance, site-specific harvest seasons, please see the two-page 2024 Puget Sound clam, mussel, and oyster season guide. 

A list of the tides in the Puget Sound region that favor good harvest results can be found in the one-page 2024 best clam and oyster harvest tides chart. 

Harvesting shellfish legally and safely

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

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.
