Just as a health alert ended for one Nebraska lake, it began for another.
State authorities have issued a health alert for toxic blue-green algae for Rockford Lake in southern Nebraska’s Gage County.
That news comes on the heels of the state lifting a health alert for another southeastern Nebraska lake, Kirkman’s Cove in Richardson County.
The state routinely monitors lakes during the summer vacation season.
Samples taken from Rockford Lake have 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.)
Health alerts last for at least two weeks, because lakes must record two consecutive weeks of readings below the threshold before the state lifts the alert.
Swimming beaches have been closed at Kirkman’s Cove. Recreational boating and fishing are permitted. The public is advised to avoid ingestion of water or full immersion in water. Camping, picnics, and other outdoor activities will continue during the health alert.
Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site, http://deq.ne.gov.
