Lower Salinas River Fecal Coliform TMDL

Information

Problem Statement - The beneficial use of water contact recreation is not protected in the impaired reaches of the Lower Salinas River Watershed, including Lower Salinas River (from the Chualar River Road, downstream to the Salinas River Lagoon (North)), Old Salinas River, Tembladero Slough, Salinas Reclamation Canal, Alisal Creek, Gabilan Creek, Natividad Creek, Salinas River Lagoon (North), Santa Rita Creek, Quail Creek, Chualar Creek, and Towne Creek because fecal indicator bacteria concentrations exceed existing Basin Plan numeric water quality objectives and/or USEPA guidelines protecting this beneficial use. All reaches in these waterbodies are impaired. The Ocean Plan and Basin Plan also contain Shellfish Harvesting (SHELL) and Non-contact Water Recreation (REC-2) water quality objectives. Waterbodies with SHELL beneficial use impaired by bacteria will be addressed in a separate TMDL project and/or standards action.
