Clam, mussel, and oyster season OPEN for harvest year-round.
Birch Bay State Park is subject to frequent biotoxin closures. Harvesters are urged to check the Department of Health water quality status the same day they plan to harvest.
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 at lower tidal elevations.
There are some oysters on this beach, but they are not abundant.
