A shallow, landlocked body of water that has a high concentration of salts on the San Andreas Fault at the southern end of California. Sustained mostly by agricultural runoff replete with fertilizers, causing algal blooms that provoke fish die-offs. The Salton Sea is beset by serious problems. The Sea has no outlet, so the water is lost only through evaporation, leaving dissolved salts behind and gradually raising salinity. The fertilizers are introduced into the air as the shoreline recedes. The Sea's salinity has now reached 44 parts per thousand, about 25% higher than ocean water.
