The delta smelt (Hypomesus transpacificus) is an endangered slender-bodied smelt, about 5 to 7 cm ( to in) long, in the family Osmeridae. Endemic to the upper Sacramento-San Joaquin Estuary of California, it mainly inhabits the freshwater-saltwater mixing zone of the estuary, except during its spawning season, when it migrates upstream to fresh water following winter "first flush" flow Class: Actinopterygii. We study the key role fish populations play in supporting fisheries and ecosystem processes. Our work includes fish life history and limiting factor analyses, predator-prey interactions and aquatic food web studies, and monitoring fisheries harvest and management trends. The first positive record of its occurrence in California is that of Raquel () who described the collection of a cm male weighing kg in the Clifton Court Forebay, an impoundment near Byron, Contra Costa County, which uses Sacramento-San Joaquin Delta water. Clifton Court Forebay Continue implementing actions to reduce mortality of listed fish species at the Clifton Court Forebay; these measures would include (a) continued evaluation of predator relocation methods and (b) controlling aquatic weeds. Increase species survival and control weeds to reduce impacts on the SWP’s physical facilities.

Additionally, Fish and Game would establish a "hot spot" for stripers at Clifton Court Forebay near Tracy, and adjacent waterways, where the daily bag would be 20 fish, with no minimum size limit. The possession limit would increase to 40 fish in the area. This is the first Figure 1.

Also, sediment transport characteristics of the DMC and the California Aqueduct were compared. Significant differences between the two intake facilities were indicated. Approximately 70% of the sediment entering the Aqueduct was deposited in Clifton Court Forebay and Bethany Reservoir, while only 10% was deposited in the DMC intake channel.
