Harvest profile

This beach has been enhanced with  oysters.

The most productive area of the beach for Manila and native littleneck clams at Illahee State Park was wiped out by a major slope failure sometime around 1994. Material that came off the hillside blanketed the most productive ground out to deep water. Some native littleneck clams are can still be found in the mid to high intertidal zone. Horse clams, Manila clams, butter clams and cockles are available, but not abundant. In the past there has been some wild geoduck on this beach although digging for them can be very difficult in the boulder and cobble substrate. Clam "necks" (siphons) visible in the hardpan at the south end of the beach are piddock clams, not geoducks. These clams are embedded in very hard substrate and cannot be easily removed from the beach. 

This is a very good oyster beach.
