A health alert has been issued for Swan Creek Lake #5A, also known as Willard Meyer Recreational Area, in Saline County due to toxic blue-agree algae.
An alert remains in effect for Pawnee Lake in Lancaster County.
Samples taken this week from Swan Creek Lake indicate levels of total microcystin (a toxin released by certain strains of blue-green algae) exceeded the state health alert threshold of 20 parts per billion. Readings at Pawnee Lake fell below the threshold, but Pawnee must pass two consecutive rounds of testing before state officials will lift the alert.
Signs have been posted to warn the public. Swimming beaches have been closed.
Recreational boating as well as fishing are permitted. The state advises avoiding full immersion in the water during the alert. Public areas for camping, picnics, and other outdoor activities remain open.
The state takes samples from 50 public lakes weekly throughout the summer vacation season.
Sampling results for toxic algae and bacteria will be updated every Friday. Click here for results at the NDEQ’s web site.
