MILWAUKEE -- The Milwaukee Health Department said Tuesday, August 1st water quality testing conducted by the University of Wisconsin-Milwaukee Joseph J. Zilber School of Public Health indicated the presence of cyanobacteria (or blue-green algae) in the lagoon at Veterans Park. The discovery could lead to illness -- and similar conditions are being suspected in connection with the death of a dog in Madison.

"I was commenting to my daughter Felicity here that it is very green!" Kathleen Deboer said. "I suppose it would make me think twice."

Health officials noted there is no swimming allowed in the lagoon.

At this time, no reports of illness related to activities at the lagoon have been reported. Informational signs notifying the public will soon be posted at Veterans Park.

Blue-green algae is a common algae found in rivers, lakes, and ponds throughout Wisconsin. These algae can form “blooms’ due to high nutrient levels or when environmental conditions are favorable. Blooms may appear as scum layers or large floating mats and often have a bluish-green color and unpleasant odor. While not all algae blooms are harmful, some species of blue-green algae naturally produce a toxic substance that can cause illness or health effects in humans or animals through direct contact, ingestion, or inhalation.

"I'm not going to try and splash the water," Azul Alcantara, age nine said.

The Alcantara family already has a plan in place before they head out onto the water.

"If I go use it, the canoe or the paddle, I'll have to re-wash it if I really have any contact," Israel Alcantara said.

In Madison, health officials are investigating after a three-year-old Cavalier King Charles Spaniel named Lucy died after swimming in Lake Mendota. It happened Sunday, July 30th.



Commissioner of Health Bevan Baker issued this statement on the matter:

"The detection of blue-green algae in a local waterway serves as a reminder that any natural body of water can contain organisms that present a health risk. During these warm summer months, all area residents taking part in recreational water activities should be aware that algae may be present and take appropriate precautions."

  • Do not eat fish from or drink water that appears foamy or scummy.
  • Do not let dogs drink or swim in lake water during an algal bloom.
