LINCOLN, Neb. (AP) -- "The latest health alert for toxic blue-green algae includes Conestoga Lake. Water at the 230-acre lake, which is a few miles southwest of Lincoln in Lancaster County, exceeded safety levels for microcystin toxin, said the state Department of Environmental Quality.
Conestoga is the fifth lake to have health warnings posted so far this year. Twenty-six lakes were similarly affected last summer in Nebraska, as far west as Lake McConaughy and east as Carter Lake, which is half in Iowa, half in Nebraska -- just northeast of downtown Omaha.
Boating and fishing are permitted as long as people avoid summer fun that could lead to their swallowing water. People can still use the public areas for camping, picnics and other outdoor activities.
Pets and farm animals have died from drinking water containing toxin from blue-green algae. The toxins break down naturally in the water, often within a week or two after the blue-green algae bloom has subsided. However, algae blooms can recur."
