A health advisory for blue-green algae at Marion Reservoir was lifted Thursday a week after a similar advisory was lifted at Marion County Park and Lake.

Six other lakes and reservoirs in the state remain under blue-green algae advisories or warnings. The nearest is Old Herington City Lake in Dickinson County. The others are in Phillips, Barton, Trego, Jewell and Johnson counties.

Advisories mean that although boating and fishing may be safe, wading and swimming for people, pets and livestock are discouraged. Warnings mean the bodies of water are closed for recreational activities.

The Kansas Department of Health and Environment advises that humans, pets, and livestock should not drink untreated water or consume dried algae. Fish should be rinsed with clean water. Only the filet portion should be eaten.
