Lower Clear Creek Phase 2 Restoration Project
Project Overview
Basics
Lower Clear Creek Phase 2 Restoration Project
Planning/Design
Metro’s Clear Creek natural area includes 686 acres and 18,480 linear feet (3.5 miles) of Clear Creek. Clear Creek is a large tributary supporting relatively abundant salmon populations in the lower Clackamas River and is home to the last significant run of late-run coho salmon in the lower Columbia River Basin.
Restoration work is proposed to restore both riparian, floodplain and stream complexity by placing large wood, slash and other woody debris by helicopter in Clear Creek over 3.5 miles. This builds on previous work completed by PGE, CRBC and Metro in this reach of Clear Creek.

Focal Species
Focal Species
While Chum are currently not in the watershed, lower Clear Creek would potentially provide habitat for Chum salmon if reintroduced.
Increased habitat complexity on Clear Creek will provide cover for migrating adult and juvenile fish and recruit gravel for spawning fish. Without large logs the flashy nature of this system washes out gravels.
Lower river tributaries on large river systems attract fish because of cold water conditions. Juvenile Fall Chinook may use lower portions of Clear Creek when the mainstem Clackamas River is too warm to support fish.
Lamprey are know to spawn in lower Clear Creek. Restored habitat complexity on Clear Creek will provide cover for adult fish and recruit gravel for spawning fish. Fine sediments in alcove, the pond and side channel will provide rearing habitat for lamprey ammocetes.
