LINCOLN, Nebraska — State health and environment officials have issued a health alert for toxic blue-green algae at Willow Creek Lake in northeast Nebraska's Pierce County.
Officials say in a news release Friday that the alert was issued following tests of the lake water.
Skin exposed to the toxin from certain strains of blue-green algae can develop rashes and blisters. Someone who drinks water containing the toxin is at risk for headaches, nausea and muscular pain.
Weekly water sampling has been conducted at 50 public lakes in Nebraska since the beginning of May.
