Santa Maria Watershed TMDL - Fecal Indicator Bacteria


Problem Statement - Fourteen waterbodies (Alamo Creek, Blosser Channel, Bradley Canyon Creek, Bradley Channel, Cuyama River (above Twitchell Reservoir), La Brea Creek, Little Oso Flaco Creek, Main Street Canal, Nipomo Creek, Orcutt Creek, Oso Flaco Creek, Oso Flaco Lake, Santa Maria River and the Santa Maria River Estuary) in the Santa Maria Watershed are impaired due to exceedance of the water quality objectives for total coliform and/or fecal coliform and/or E. coli. Consequently, the beneficial uses of contact recreation (REC-1) and shellfishing (SHELL) - in the Santa Maria Estuary only - are not being protected. This project identifies the causes of impairment and describes solutions to achieve water quality objectives and protection of beneficial uses.
