Big Creek is an ocean tributary flowing directly into the Pacific Ocean, about 10 miles south of the town of Yachats.
The site, now owned by Oregon Parks and Recreation Department (OPRD), was degraded by land clearing and grazing, removal of large wood from the stream, invasive plants, and unnatural fill in the floodplain. These actions greatly impacted instream complexity, floodplain and wetland connectivity, and riparian vegetation; all factors that limit Oregon Coast Coho (OCC) and other salmonid production.
This project improved instream, floodplain, and wetland function by removing introduced fill in 14 acres of floodplain, instream material placement to remedy channel incision, and placement of large woody debris.
Wood placement includes 10 instream log structures and over 200 pieces on the Big Creek floodplain. This increased large wood loading will further increase connectivity and side channel development over time.
Riparian planting and seeding will improve the functioning of the riparian zone and enhance a pollinator corridor between two known reproduction sites for the endangered Oregon silverspot butterfly.
Project partners include OPRD, Oregon Department of Fish and Wildlife, US Forest Service, Siuslaw SWCD, Oregon Department of Transportation, and the Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians.
