Spirit Lake, Iowa (RI) — An Iowa Department of Natural Resources fisheries biologist says the agency is receiving reports of blue-green algae in several of the Iowa Great Lakes.
Andrew Carlson, with the DNR’s Spirit Lake office, says algae blooms are common this time of year.
As algae blooms die, they release gases that can create odors and discoloration.
Carlson provided tips for those who want to swim in one of the seven natural lakes.
Based on early-July water samples, the DNR’s website shows swimming is not recommended at Emerson Bay Beach on West Okoboji. A mid-June test prompted a warning at Crandall’s Beach on Big Spirit Lake due to elevated E. coli, but July 1st testing found no bacteria or algae, and the site is now classified as OK for swimming.
