The Southern California Steelhead Distinct Population Segment (DPS) occurs from the Santa Maria River to the Tijuana River at the United States and Mexican Border in seasonally accessible rivers and streams.[1] Steelhead (Oncorhynchus mykiss) in the Southern California Steelhead DPS, much like its relatives further north, requires sufficient flows in their natal streams to be able to return from oceans and lakes to spawn. Due to the extended periods of drought throughout their range, Southern California steelhead are most commonly seen during periods of increased rainfall, such as El Niño events.[2] Declared federally endangered in 1997,[3] the geographic range of the DPS when first listed extended from the Santa Maria River south to Malibu Creek. In 2002 steelhead were discovered in San Mateo Creek on the county line of Orange and San Diego counties. With this discovery the range of the DPS was extended to include Los Angeles, Orange, and San Diego counties. [4]
