Harvest profile

This beach is a very popular place to dig for geoducks. A tide lower than -2.0 feet is best for geoducks. Look for areas of sand and small gravel and avoid the cobble and hardpan portions of the beach. The north end of the island is the least productive. The best spots are near the middle of the island on the west side and at the extreme south end.  There are also geoducks on the west side of Hope Island, but they are not as abundant as on the south end and west side. There are abundant rough piddocks on Hope Island. They are easy to confuse with geoducks. The piddock's siphon (neck) is split and the geoduck's siphon is single. Piddocks prefer clay and hardpan substrate and are extremely hard to dig. There are patches of large native littleneck clams on Hope Island. They can be found in areas of sand and gravel near the middle of the island on both the west and east sides. Manila clams are not abundant on Hope Island, but there is one good spot on the extreme south end of the island in patches of sand and gravel substrate. There are butter clams on this beach. They can be found in the mid-lower intertidal zone in the sand and gravel and cobble substrate. Horse clams are present in fair numbers in the lower intertidal zone in sand and gravel.

This beach has been planted with oysters in the past and there may still be some available. Most of the oyster resource is on the west side of the island near the south end.
