The Barnaby Rip-Rap Removal Project was implemented on an active side channel of the Skagit River near Barnaby Slough on property owned by the Washington Department of Fish and Wildlife (WDFW). Large rip-rap rock had been placed in the side channel to protect a downstream steelhead trap; however the trap was abandoned in 1989 and the rock no longer needed. Flood events did remove some of the rock but much of the rock remained in place. The rock continued to prevent surface flow down the channel and the channel was considered lost as habitat for spawning chum and coho salmon and other native fish.

In 1998, SRSC designed the project and acquired permits, and WDFW removed approximately 100 meters of rip-rap at the upper end of the side channel, allowing for natural channel forming processes to be restored. A second phase of rip-rap removal was implemented in 2000, removing an additional segment of rip-rap. Fish monitoring done immediately after the project showed excellent response, with considerable numbers of chum salmon spawners utilizing the restored channel.
