Document Description
The Project was initiated in 1991 and involves the seasonal installation and removal of three flow-control temporary rock barriers to reduce adverse water levels and circulation impacts caused by the State Water Project (SWP) and Central Valley Project (CVP) on local agricultural diverters within the South Delta Water Agency (SDWA). The flow-control temporary rock barriers are installed at Middle River near Victoria Canal (MR), Old River near Tracy (ORT), and Grant Line Canal near Tracy Boulevard Bridge (GLC). The MR, ORT, and GLC barriers are designed specifically to address adverse impacts on local diverters within the South Delta The Project will result in continued permanent impacts to 0.27 acres and cumulative temporary impacts to 6.05 acres of longfin smelt (Spirinchus thaleichthys), Delta smelt (Hypomesus transpacificus), winter-run Chinook salmon (Oncorhynchus tshawytscha), and spring-run Chinook salmon (Oncorhynchus tshawytscha) habitat. The Project will also result in permanent and temporary impacts to Swainson’s hawk (Buteo swainsoni) habitat during a sensitive time period. The project is expected to result in incidental take of longfin smelt, spring-run Chinook salmon, and Swainson’s hawk which are designated as a threatened species under CESA and Delta smelt and winter-run Chinook salmon, which are designated as an endangered species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
