Although clamming is a pastime throughout the beaches and estuaries of the Pacific Northwest, Waldport’s Alsea Bay is unique within Oregon because it’s the only estuary in which, by law, the tide does not have to be negative in order to clam.

Here, at low tide, recreationalists and subsistence clammers come out to get their bounty of the most common bay clams, including gaper clams (Tresus capax), soft-shell clams (Mya arenaria, non-native from New England), purple varnish clams (Nuttallia obscurata, non-native from Japan), and heart cockle clams (Clinocardium nutallii). The largest clams will be found in the deepest water channels, and gapers are more obscure and will only be found west of the bridge, while purple varnish (and ghost shrimp) will be found in near-endless quantities outside the channels.

If crabbing is what you’re looking for, head east to the Alsea Bay Marina, where abundant dungeness crab (Metacarcinus magister) call these deeper waters home.

Note: The Oregon Department of Fish and Wildlife also has specific locations within Alsea Bay in which clamming is permitted. See a map here.
