Utah Lake seeing less toxic algal blooms

UTAH COUNTY, Utah — The Utah County Health Department has downgraded health warnings related to toxic algal blooms at Utah Lake’s American Fork, Lindon, and Saratoga Springs marinas.

The warning advisories for the lake are now being called “health watches.” 

Dr. Hannah Bonner, an environmental scientist with the Utah Division of Water Quality said this is a welcome change.

“Oftentimes, we see blooms worsening during the summer. This is definitely movement in a good direction and opens up some recreational opportunities at those areas of the lakes that Health Department other agencies are recommending against earlier in the summer,” said Bonner. 

The latest report shows the harmful algal blooms are no longer present at the American Fork, Lindon, and Saratoga Springs marinas, after three weeks of sampling.

What are toxic algal blooms?

According to the Utah Division of Water Quality, algal blooms are aquatic bacteria that become toxic when they multiply, quickly creating a “bloom.” They harm ecosystems and can cause illnesses that impact the kidney, liver, or neurologic system.

Harmful algal blooms have been a persistent problem at Utah Lake. There are a few parts still under the warning advisory, including the southern end and Provo Bay. 

Health officials ask people who are recreating to be on the lookout and avoid patches of blue-green algae blooms in the water. They recommend people avoid swimming, drinking, or exposing pets to any water that may have algal blooms. 

“We’re just saying when you are recreating avoid areas of visible algae,” said Bonner.
