The North Yakima Conservation District removed the Upper Lust irrigation diversion dam that was a fish passage barrier on Cowiche Creek northwest of Yakima, WA. Three vortex weirs and a J-hook vane were installed to stabilize the stream after the dam was removed. One rootwad was installed to improve fish habitat. Banks were sloped back and areas disturbed by construction were revegetated. The original proposal was to remove both the Upper Lust and Lower Lust diversion barriers. However, only the Upper Lust diversion barrier was addressed within the timeframe of this grant. The Lower Lust diversion barrer is being addressed as part of a larger complimentary project wihin the Cowiche Creek Water Users Association and Yakima Tieton Irrigaiton District that will address fish screening needs and establish a large trust water right. The larger project will reduce or eliminate the need to divert waters from the Cowiche Creek, allowing the removal of Upper Lust diversion barrier and two more diversion barriers (one upstream and one downstream of the Upper Lust diversion). No other unnatural barriers are known at this time. Therefore removing these three diversions will allow full anadromous access into the upper South Fork Cowiche watershed. This project witl benefit Chinook and Coho salmon, steelhead, and Cutthroat Trout.
