DESCRIPTION
This project replaced 2 eight foot culverts with a single span bridge on Beaver Creek. The Beaver Creek and Frazer Creek (tributary to Beaver Creek) drainages experienced significant disturbance in July as the result of lightning-caused wild fire, and in August from two separate mudslide / slope failure events. The BAER review for the watersheds indicates that both creeks are likely to experience dramatically increased flows following rain events, together with a substantial sediment load and debris flows, for the next 3-5 years. The mud / debris flow which occurred on August 20 following heavy rain, resulted in a debris plug at the Stokes culverts on Beaver Creek. This crossing is located approximately 500 feet downstream from the point at which Frazer Creek empties into Beaver Creek. The plugged culverts resulted in over-bank flooding downstream of the crossing, destroying adjacent riparian habitat. Debris material backed up above the crossing for about 50 feet. Without modification, it is likely that this form of maintenance will continue to be necessary following each subsequent rain event. Consequently, that portion of Beaver Creek lying downstream of the access crossing (about 3 miles) will not receive the benefit of the natural accumulation of woody debris, and could impede fish passage if the maintenance on the current culverts is not maintained. The Stokes Bridge on Beaver Creek was funded via BPA Accords/Colville Confederated Tribes under BPA project 2007-224-00, Co
