SACRAMENTO, California The U.S. Army Corps of Engineers Sacramento District’s Pine Flat Lake has been experiencing algae blooms and signage has been posted around the lake as a precaution. Water samples collected June 15 by the California State Water Resources Control Board indicate the presence of cyanobacteria in the lake water. Cyanobacteria can lead to the production of toxins in the water, however, toxin levels were NOT detected in the recent tests, and the conditions of the algae blooms are evolving on a daily basis.

For current information on the algae bloom, check our Pine Flat Lake web page at


Pine Flat Lake park rangers are urging lake users to follow all

recommendations on posted signage, and “When in doubt, stay out.”


The U.S. Army Corps of Engineers is among the nation's leading federal providers of outdoor recreation with more than 5,000 recreation sites at 403 lakes and river projects located in 43 states.
