The Gose Street Bridge site was a fish passage barrier limiting access to the Mill Creek drainage which includes 52 miles of stream habitat. At the Gose Street Bridge, the concrete flood-control channel that protects Walla Walla had a steep drop for about 600 feet. During times of low flows, the water was shallow, warm, and moving quickly across a wide, steep channel. WWCCD and the Confederated Tribes of the Umatilla Reservation (CTUIR) worked to design a new system to eliminate the fish barrier. The project consisted of installation of two pool and chute fish ladders, a low-flow channel, and two concrete cross-channel weirs. Most of the work was completed in the fall of 2006 with final completion scheduled for the in-water work window of 2008. Funding was provided by the Snake River Salmon Recovery Board (Washington State Recreation and Conservation Office) the Bonneville Power Administration, and the CTUIR.
