Background:

Richardson Bay (also known as Richardson’s Bay) is an arm of San Francisco Bay located just northeast of the Golden Gate in southern Marin. It is enclosed by the cities of Sausalito, Mill Valley, Tiburon and Belvedere, as well as an unincorporated portion of Marin County. The Richardson Bay Audubon Sanctuary includes 900 acres of marine habitat between Belvedere and Tiburon. The Bay is widely used for recreational activities including boating, kayaking, rowing, and swimming. Historically, Richardson Bay supported shellfish such as oysters, mussels, and clams. Because it is shallow and enclosed, with little tidal action or freshwater inflow from local creeks, the Bay has only a limited ability to disperse or dilute pollution. Richardson Bay is listed by U.S. EPA as impaired by pathogens. The listing was made in response to observations of elevated bacteria levels in the Bay, which indicate the presence of fecal contamination and health risks from water-borne pathogens to shellfish harvesters and recreational users of the Bay. The Richardson Bay TMDL examines these water quality issues, identifies sources of pathogen contamination, and specifies actions to restore the health of the Bay.
