This week’s On the Radio segment looks at a type of hazardous algae that’s become increasingly common in Iowa waterways. Listen to the audio below, or continue reading for the transcript.
As the summer comes to an end, late season beach-goers are advised to take extra precaution as algae blooms in Iowa lakes can be at peak levels.
This is the Iowa Environmental Focus.
Hot August temperatures coupled with high levels of nitrogen and phosphorus in Iowa waterways provides the ideal breeding ground for algae. Certain forms of blue green algae can contain toxins that are harmful to humans and have even been known to kill dogs, livestock, and other animals.
Blue green algae are generally visible on the surface and can give the water a consistency similar to paint. The Iowa Department of Public Health advises any persons to immediately wash algae off themselves or pets that come in contact with it.
So far this summer, Saylorville Lake and Lake Red Rock, both in central Iowa, have reported high levels of blue green algae, and at least six other state-operated beaches across the state have seen high enough algae levels that swimming was not recommended.
