Project: Deer Creek Irrigation District Dam Fish Passage Improvement Project

Description: The reaches of Deer Creek that flow through the Sierra Nevada foothills contain high quality spawning and rearing habitat for salmonids, with good year-round water quality and quantity, and relatively low levels of water diversion and other human development. To migrate to and from this upstream reach, however, adult and juvenile salmon must pass through the lower reach of the creek that flows through the Central Valley. Passage through this reach is one of the major threats discussed in the 2014 National Marine Fisheries Service (NMFS) recovery plan for spring-run Chinook (NMFS 2014 and CDFW 2014). The Project will restore full upstream and downstream passage for salmonids at the DCID diversion dam for all life stages of Chinook salmon and steelhead, and other aquatic species, while meeting DCID’s irrigation needs. Project objectives include modifying the dam approach and diversion facility to improve flow characteristics and reducing the overall height of the diversion structure.
