HUMBOLDT, Neb. (AP)-- State officials have issued a new health alert for a lake in the southeastern corner of Nebraska tainted by toxic algae.
The Nebraska Game and Parks Commission says a new alert has been issued for Kirkman's Cove near Humboldt. Health alerts also continue for Rockford Lake in Gage County, Wagon Train Lake in Lancaster County, and Willow Creek Reservoir in Pierce County.
Samples taken earlier this week at the lakes showed elevated levels of microcystin, a toxin released by certain strains of blue-green algae.
The alerts mean swimming beaches at the lakes are closed. Boating and fishing are permitted, but officials advise people and pets to avoid exposure to the water. People can still use the public areas for camping, picnics and other outdoor activities.
