This salmon enhancement project is located on an unnamed right bank tributary to mainstem Perry Creek in Thurston County (WRIA 14). Mainstem Perry Creek enters Mud Bay and is a productive salmon stream. The mouth of the Perry Creek tributary (14.0002) culvert project is approximately 500m upstream from the estuary and is about 2100m in total length. This project is located on a private road that accesses about 5 acres of forestland on the opposite side of the creek from the landowner's home. The landowner would like to keep access to their property while improving salmon passage and culvert maintenance. This project will remove two inadequate barrier culverts and replace them with a single large squash culvert. The proposed culvert will be 9' wide x 5' tall x 30' long. This culvert will satisfy the "no slope" option outlined by WDFW in their recent 2003 Culvert Manual. The culvert will be large enough to pass high water flows, sediment bed-load material, LWD, and salmon at all life stages. This project is important to create additional spatial distribution for chum, coho, and cutthroat. Perry Creek is a dominant chum stream in the South Sound that produces thousands of chum annually. There is a natural waterfall on mainstem Perry Creek (upstream of the tributary confluence) that prohibits salmon passage. This project will improve existing access on stream 14.0002 that will be used predominantly by rearing species of salmonids.
