A health alert has been issued for Pawnee Lake in Lancaster County. Alerts continue to be in effect at Kirkman’s Cove in Richardson County and Iron Horse Trail Lake in Pawnee County.
Samples take last week at Pawnee registered above the state health alert threshold of 20 parts per billion (ppb) of total microcystin (a toxin released by certain strains of blue-green algae.)
The latest readings taken at Kirkman’s Cove and Iron Horse Trail Lake were low, but the alerts continue until the lakes pass two consecutive weeks of readings below the state threshold.
Signs have been posted to warn the public at both lakes. Swimming beaches have been closed.
Recreational boating as well as fishing are permitted. The state advises to avoid 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.
