UPDATE TO BELOW PINE FLAT ALGAE PRESS RELEASE AS OF AUGUST 10, 2018

The Central Valley Water Board has completed a third round of testing for toxins at the U.S. Army Corps of Engineers Sacramento District’s Pine Flat Lake.

     Five locations sampled within Pine Flat Lake reveal that conditions of the lake are improving and no cyanotoxins were found to be present. There has also been a noticeable change in water color, with no visible surface scum and no distinct green particulate matter in the water.

     Cyanobacteria was found to be present in the lake in mid-June following water testing by the CVWB. Its presence can lead to the production of toxins in the water, however, toxin levels have NOT been detected in any of the recent water samples from Pine Flat Lake.
