Samples taken last week at the lakes show they measured above the threshold of eight parts per billion of total microcystin, which is a toxin released by certain strains of blue-green algae.
When a health alert is issued, signs are posted to advise the public to use caution, and designated swimming beaches are closed during the alert.
Recreational boating and fishing are permitted, but the public is advised to use caution and avoid exposure to the water, particularly by avoiding any activity that could lead to swallowing the water.
Do not let pets get in the water or drink from the lake. People can still use the public areas for camping, picnics, and other outdoor activities.
