WDFW Beach Season Information
Indian Island County Park/Lagoon Beach: Clam, mussel, and oyster seasons OPEN April 1 and projected to CLOSE for harvest May 31, 2025, from the jetty boundary with Port Townsend Ship Canal/Portage Beach eastward to the beach access stairs on Flagler Rd near milepost 4. Harvesting seasons apply to salt marshes and tidal beach area.
Isthmus Beach: Clam, mussel, and oyster season OPEN for harvest year-round from the beach access stairs on Flagler Rd near milepost 4 eastward toward the land bridge between Marrowstone and Indian Islands.
The boundary between Indian Island County Park/Lagoon Beach/Isthmus Beach and Port Townsend Ship Canal tidelands is just north of the landward end of the jetty at the south end of the Ship Canal. See beach map below for the approximate north boundary of Indian Island County Park/Lagoon Beach/Isthmus Beach. Because Indian Island County Park may be open for clam harvest when Port Townsend Ship Canal is closed, harvesters are encouraged to be familiar with this boundary. The southeastern boundary between Lagoon Beach and Isthmus Beach is marked by the access stairs on Flagler Rd near milepost 4. Lagoon Beach and Isthmus Beach have different harvest seasons.
WDFW shellfish seasons indicate the specific times of year when harvesting is permitted. Before heading to the beach, please also check the Department of Health (DOH) information below which is related to health of the shellfish and may be updated daily. To harvest on this beach, it must be both during the WDFW approved season and approved by the DOH.
Lagoon Beach: This is a good clam beach. There is over a mile of public beach. There is good digging for butter clams, native littleneck clams, Manila clams, cockles and horse clams just below the main (north) parking lot in the area around the tidal channel that drains the lagoon. The littleneck clams tend to be higher on the beach while the butter and horse clams are lower in the tidal zone. There are productive clam areas in sand and gravel substrate on this beach from the main county park (north) access all the way to the south border. Geoducks may be found on this beach below the -2.0 foot tide level. Oysters may be found in very limited numbers.
Isthmus Beach: The eastern end of the Indian Island County Park beach complex consists of large sand flats that are exposed during minus tides. Horse clams and cockles are found in this area. Oysters are not common on this beach.
