Sacramento Splittail

The Sacramento splittail is a hardy minnow native to the upper San Francisco Estuary and the Central Valley in California. It once swam in lakes and rivers throughout the Central Valley and in the Sacramento-San Joaquin River Delta, but massive water diversions and alteration of important spawning and rearing habitat have driven this formerly common species to near extinction. Remnant populations of splittail in the Delta require adequate freshwater outflow and periodic floodplain inundation. (USFWS)
