The North Yakima Conservation District propose to develop a preliminary design to improve fish screening and passage at three irrigation diversions, as well as to improve passage, flow management, and provide water measuring at the existing diversion dams that divide north and south fork flows. The project is located on Wenas Creek from approximately 200 feet and 0.75 miles upstream of Sisk Road. The three diversions consist of a right bank gravity diversion that is unscreened and creates a 3-foot drop in water surface elevation when check boards are added. The second diversion consists of a pumping station located on left bank that is not equipped with a compliant fish screen and is regularly inundated with alluvial deposition which requires instream manipulation with equipment. The third diversion dam consists of an unscreened gravity diversion that creates a 1.5-foot drop in surface water elevation. The diversion dams that splits flow between the forks consists of two check dams that divert flows and create a 1.5-foot drop in water surface elevation. The project will use desk top and field investigations to produce conceptual design alternatives aimed at potential consolidation of the three most upstream features and infrastructure to provide fish passage and screening for all life stages of salmonids at all periods of the hydrograph for all structures. A preferred alternative will be chosen and developed into a more detailed preliminary design.
