On July 9 staff from the Central Valley Regional Water Control Board were at Wright’s Lake collecting water samples after an unusual algal bloom that was reported at the lake. The algal bloom was suspected of being benthic cyanobacteria, a blue-green algae that produces a toxin that can be deadly to humans and animals. The initial lab results were negative for cyanobacteria. Further chemical tests were conducted to be on the safe side and those also came back negative.
According to the board, the algal toxins microcystin and cylindrospermopsin that are produced by cyanobacteria and are toxic to most vertebrates were not detected.
