HOT WEATHER: Affecting Fish Too

The hot and dry conditions across the state continue to take a toll on Iowa fish.

A 42-mile section of the Des Moines River in southeastern Iowa is experiencing one of the longest fish kills in recent history. The DNR says low water flows and high water temperatures are to blame.

“River conditions are getting worse, increasing an already stressful condition for fish,” said Mark Flammang, fisheries biologist with the Iowa Department of Natural Resources.

The combination of low water and high temperatures stresses fish, especially those susceptible to warmer water, like sturgeon, northern pike, yellow perch and walleye.

Channel catfish and bullheads, two species that are more tolerant of warmer water, are also showing signs of stress.

Reports show approximately 58,000 dead fish already.
