BISMARCK, N.D. (AP) - North Dakota’s Health and Agriculture departments have withdrawn a blue-green algae advisory for Lake Ashtabula in Barnes County.

The warning was issued in August after a dog was reported dead. Monitoring showed high levels of microcystin, a cyanotoxin toxin caused by blue-green algae.

The Health Department says the U.S. Army Corps of Engineers has noted a significant improvement in water quality at the lake, so the advisory is no longer necessary.

Hot summer weather can contribute to the production of the algae that’s also known as cyanobacteria. People and animals who ingest affected water can get sick and even die. There’s no known antidote for the toxins.

People are urged to err on the side of caution and avoid water that looks discolored or scummy or has a foul odor.
