Animal, Bird Deaths at Lake Might Be from Blue-Green Algae

HURON, S.D. (AP) — South Dakota officials say the recent deaths of animals and birds at Lake Byron in Beadle County might be due to bacteria producing toxins in the water.

The Huron Plainsman reports that the state Game, Fish & Parks Department is cautioning people to avoid contact with the water and to keep their animals away from the lake while water samples are tested.

Late summer and early fall offer prime conditions for blue-green algae growth in many waters. Swimmers in waters with the bacteria might have allergic reactions, while animals, birds and fish can be poisoned by high levels.

The algae blooms occur during hot, dry weather. The threat diminishes once the weather turns colder.
