Caution, Blue-Green Algae

Blue-green algae, also known as cyanobacteria, has been reported in Devil’s Lake and can pose risks to people and pets. Of course, it’s not always easy to spot and just this morning I spoke with a park visitor with their (Off-leash) dog just about to toss a ball into a questionable area. Thankfully the pup didn’t go in!

Identifying Blue-Green Algae Blooms When conditions are right, blue-green algae grow rapidly and float to the surface, forming scum layers or floating mats. If the water resembles “pea soup”, blue or green paint, or has a scum layer or puffy blobs on the surface, it’s likely an algae bloom. Often though, it can be pretty hard to see, especially on wavy or disturbed water, so “better safe than sorry” is the best approach!

Safety Measures Avoid swimming, diving, boating or kayaking in algae-infested water. Don’t let children play with the scum layers. Keep pets away from such water as ingestion can be harmful.

If you come into contact with blue-green algae, rinse off thoroughly. If symptoms occur, contact your health care provider or call the Poison Control Center at 1-800-222-1222. Report blooms to the Wisconsin Harmful Algal Blooms Program (WI DHS).

Pet Owners Before letting your dog swim or wade, inspect the water. If you decide to let them swim, rinse off your dog immediately after they’ve been in the water. If they exhibit signs of sickness post-exposure, contact your vet.

There’s no quick solution once blue-green algae appear and it does seem to be blooming very early for Devil’s Lake this season. Ultimately, it’s a good idea to be alert for Blue-Green algae, before you, your family, or your pet go into the lake!
