In August 1997, NMFS listed the Southern California steelhead Evolutionarily Significant Unit (ESU) as an endangered species and defined its southern limit as Malibu Creek in Los Angeles County, California, based on the best information available at that time. In February 2000, NMFS designated critical habitat for this ESU that includes all accessible and occupied waterways, including the adjacent riparian zone, below longstanding impassable natural barriers within the range of the ESU. There is now new information indicating that steelhead or their progeny now occur in at least two coastal river basins south of Malibu Creek, and have successfully spawned in one of these basins (San Mateo Creek). Based on this new information, NMFS is now issuing a proposed rule under the Endangered Species Act (ESA) to extend the current range of this endangered ESU to San Mateo Creek in northern San Diego County, California. Within the redefined Southern California steelhead ESU, only naturally spawned populations of steelhead, and their progeny, which reside below naturally occurring and man-made impassable barriers (e.g., impassable waterfalls and dams) are proposed for listing. At this time, NMFS is proposing to list only the anadromous life forms of Onchorynchus mykiss (O. mykiss) in those river basins south of Malibu Creek.
