IN OTTUMWA, IOWA — Driving by a boat ramp one Saturday morning last month, a local man noticed some white spots on the Des Moines River. He stopped to have a look.
Turns out the spots were fish bellies. The undersides of dead sturgeon formed glistening constellations in the muddy brown water.
In all, about 58,000 dead fish were along a 42-mile stretch, according to state officials, and the cause of death appeared to be heat. Biologists measured the water at 97 degrees in multiple spots.
