BISMARCK, N.D. (AP) - North Dakota officials say there’s no longer a health risk due to blue-green algae in the Des Lacs River in Ward and Renville counties.
The state Department of Health says follow-up monitoring earlier this week on the river northwest of Minot showed that concentrations of the bacteria were well below the risk threshold.
The production of blue-green algae, also known as cyanobacteria, often happens during hot weather in bodies of water that are used by people, pets, and livestock.
Blue-green algae discolor the water they live in, and can cause foam, scum, or mats to appear on the surface.
