This report discusses the composition of stream fish assemblages and environmental variables that were characterized at 275 sites within twenty-three watersheds tributary to the San Francisco Estuary, California, from 1993-1999. In addition, historical distribution records for 77 native and nonnative fish species were compiled to understand historical patterns of distribution and abundance, and to assess the current status of fishes.
