Water monitoring sources

The US Bureau of Reclamation initiated quarterly monitoring of the Salton Sea to provide information on changes in water quality occurring as a result of water conservation measures and other projects intended to improve or maintain water quality. Monitoring includes profiles for temperature, dissolved oxygen, pH, conductivity, and oxidation-reduction potential; major ion concentrations; nutrients; chlorophyll a; Secchi depth; and total and dissolved organic carbon.  The sampling sites illustrated in this map have been monitored quarterly on a continuing basis since 1999.
