The hot, dry summer allowed the growth of numerous algae blooms mostly in northern Iowa. The Iowa Department of Natural Resources reported 24 swim advisories at state park beaches this summer due to the presence of microcystins, toxins produced by harmful algae. That count is twice the number of swim advisories as in 2020.
