The Utah County Health Department has issued a warning that swimmers, boaters and pet owners avoid areas of bright green-colored algae growth in Utah Lake after confirming a dog died after exposure to the toxin.

Director Joseph Miller said Tuesday that the dog died within an hour of splashing in an affected area of the lake near the Lindon Marina.

"The dog owner reported that after playing in the water, and probably drinking some, [the pet] started to exhibit strange behavior within 45 minutes, including lethargy and vomiting. The dog passed away shortly after that," said Dr. Miner stated.

The algae blooms can occur at any point along the lake, health officials warn,

"Individuals should not swim or boat in areas of bright green water," said Carl Adams, Utah Department of Water Quality program manager. "The water is the color of car radiator antifreeze — it has a very distinctive color and should be avoided."

Algae growth and subsequent die-offs of the plant are part of the lake's natural biological cycle. Blooms can last for days or weeks, depending on prevailing weather conditions.

"Calm, warm, and sunny conditions promote blue-green algae growth, so it is possible [this] bloom will persist at least through the weekend, given the high pressure system currently over northern Utah," Adams noted.

Symptoms of toxic algae exposure include stomach cramps, diarrhea, vomiting, headache, fever, muscle weakness, and/or difficulty breathing.

If you think you, a loved one or pet have been exposed, you should contact your doctor or veterinarian immediately.
