What should I do if I observe a real obvious algae bloom on a fishing lake, especially when it looks like a blue-green algae bloom?
The North Dakota Department of Environmental Quality monitors water quality in lakes and rivers statewide and publishes advisories on their website when toxins are present from blue-green algae. Their monitoring relies on public reports of algae blooms, so if you see an algae bloom is occurring, the best action is to report the bloom to the DEQ so they can take some samples. Algae blooms can be reported on the DEQ’s website or by calling 701-328-5210.
If you’re recreating on a lake with blue-green algae present, avoid areas with blue-green scum, and rinse off with clean water after swimming. If a warning has been issued by the DEQ, it’s best to minimize contact with the water, especially for pets. Fish from lakes with algae blooms are safe to eat, but it’s recommended to rinse the fish with fresh water before cleaning them to remove any algae.
