Water quality is one of the greatest environmental challenges in the state of Iowa. There are many sources of pollution and finding and implementing solutions is complicated.

Iowa's rivers and streams are swollen with water right now and they're also teeming with insect life. On this Hort Day edition of Talk of Iowa Host Charity Nebbe talks with ISU Entomology Professor Donald Lewis about aquatic insects, including mayflies, dragonflies, and damselflies. He describes their life cycles and the important role they play in Iowa ecosystems. 

Later on in the program, ISU Extension Horticulture Specialist Richard Jauron answers IPR listener questions.

The floodwaters have largely receded in Davenport, weeks after the Mississippi River crested at its highest level on record and flooded parts of downtown.

The National Weather Service is raising certain flood stage categories along parts of the Iowa River. The revisions are intended to ensure flood warnings better reflect the impacts communities are seeing on the ground.
