Scope/Content: Abstract: Habitat for our native fish species has been limited since the dam building era of the 1950s and 1960s. Dry and Hopper Creeks are tributaries to the Napa River and both comprise some of the highest quality anadromous salmonid habitat on the Pacific Coast. With the cooperation of vineyard landowners, Napa County Resource Conservation District, USDA NRCS, the California Department of Fish and Game, and other partnering agencies, a concrete flashgate dam structure that prevented the upstream movement of Chinook and steelhead salmon was identified as a major barrier to fish passage in the Napa River watershed and was removed. Prior to removal, a series of treatments were designed and in the summer of 2007 the dam was replaced with vortex boulder weirs, riprap along the bank toes, and brush mattresses on the banks. After a representative first storm season, the project has performed well.(Presentation at the 2008 ASABE Annual Meeting; photographs also appended.)
