LOWER COLUMBIA RIVER WATERSHED COUNCIL

SUbarea 2 Priorities: Clatskanie Basin

The largest subarea of the Lower Columbia watersheds, the Clatskanie River is dominated by basalt geology with moderate expressions of marine sedimentary substrate in tributaries such as Conyers Creek. The Clatskanie river sub-area is bounded to the south by Bunker Hill and abuts the  Beaver creek drainage to the east. The sub-area also expresses the largest unconfined floodplain expanding over a 15% of the basin's acres. Clatskanie river receives significant flow contributions from Page Creek, Carcus, Conyers, and Little Clatskanie tributary systems.

Contributing streams: Fall Cr.,Conyers Cr.,Merril Cr., Perkins Cr., Keystone Cr.,Miller Cr., Page Cr.,Carcus Cr., North Fork, Little Clatskanie, Buck Cr.
