This beach has been enhanced with oysters. Birch Bay State Park has a large (8,255 feet of shoreline) and very productive beach, flanked by a low bank and wetlands. The park is located a few miles south of the Canadian border and is very popular with recreational clam harvesters. The clam band is a wide stretch of sand and gravel extending from the drift line down to low water. There is good digging for native littleneck clams and Manila clams in the sandy gravel of the upper intertidal and you will find butter clams, cockles and horse clams on lower tides.

This is a good beach for oysters. WDFW has planted oyster seed in an enhancement plot located on the northeast end of the beach.
