Contract Description:
CREST’s Warren Slough restoration is one of a suite projects in the eastern portion of Cathlamet Bay aimed at reconnecting wetland habitat through the defunct PNWR railroad. Warren Slough is located near RM 26, running parallel to Ziak-Gnat Creek Road northeast of the town of Knappa. The project will improve juvenile salmonid access to a 22-acre wetland complex by removing two undersized, perched culverts and replacing them with a 40-ft span bridge. Restored hydrologic connectivity and native wetland plantings will enhance vegetation diversity, increase channel edge habitat complexity, and produce a range of prey resources and foraging interface. Landscape-scale benefits include expanding upon an existing 228-acre habitat patch in a priority reach (B) of the estuary.
