State officials have issued a health alert for Lone Star Lake in Fillmore County.
Health alerts remain in effect for four other Nebraska lakes.
Alerts continue at Big Indian Creek Lake in Gage County, Kirkman’s Cove in Richardson County, Iron Horse Trail Lake in Pawnee County, and Willow Creek Lake in Pierce County.
Samples taken at those lakes this week found their water contained a toxin released by blue-green algae above the threshold set by the state. Each of the lakes recorded more than 20 parts per billion (ppb) of total microcystin (a toxin released by certain strains of blue-green algae.
State officials say that though samples taken at Kirkman’s Cove fell below the threshold this week, they were so high last week, it remains under a health alert.
Lakes must record two consecutive weeks of readings below the threshold for the state to lift the alert.
Swimming areas at the lakes have been closed. Boating and fishing are permitted. The public is advised to avoid immersion in the water or ingesting the water. Picnics and other outdoor activities are unaffected.
The lakes will continue to be monitored weekly throughout the 2014 recreational season. Sampling results for toxic algae and bacteria will be updated every Friday and posted on NDEQ’s web site. Go to it by clicking here.
