August 6, 2016 (San Diego’s East County) – State officials are warning that 150 reservoirs statewide are tainted by mercury. Ten San Diego reservoirs are contaminated, including some of East County’s most popular fishing spots.  “Mercury is negatively impacting the beneficial uses of many waters of the state by making fish unsafe for human and wildlife consumption,” the State Water Resources Control Board website warns.

However some local officials dispute those findings.


What lakes locally have mercury issues,accordingto the state?

Local reservoirs listed as "mercury impaired" on the state's document are El Capitan Reservoir, Lake Henshaw, Lake Hodges, Lake Jennings, Loveland Reservoir, Lower Otay Reservoir, Lake Morena Reservoir, San Vicente Reservoir, Lake Sutherland, and Sweetwater Reservoir, according to a California Water Boards publication released in June.
