Clear lake – Algae blooms are developing on Clear Lake, according to the Iowa Department of Natural Resources. Dense blue-green algae blooms were reported around McIntosh Woods State Park beach and expanding levels of a toxin produced by the algae were found at Clear Lake State Park beach…
Cyanobacteria, also known as blue-green algae, is a type of bacteria that uses photosynthesis to produce energy.
This week’s water test showed a spike in the levels of microcystins at McIntosh Woods of 20 micrograms per liter of water, which is above the guidelines for recreational water use
At that level, there is a moderate risk of illnesses related to exposure to the toxin.
An advisory sign for microcystins is to be posted at McIntosh Woods. A caution sign should be posted at State Park, according to the DNR.
