PLEASANT HILL, Iowa (AP) — Iowa natural resources officials are investigating a fungicide spill and subsequent fish kill in a central Iowa creek.

The state Department of Natural Resources says an estimated 180 gallons of fungicide spilled Monday when a 250-gallon container fell from a Landus Cooperative truck Monday afternoon at the intersection of state Highways 163 and 316. Some of it reached Camp Creek, where department staff found dead minnows and chubs downstream of the spill site.

Officials say the creek fish kill began east of Pleasant Hill and extended about five miles north of Runnells in Polk County.

Workers from Landus pumped up nearly 2,000 gallons of water and product from a ditch Monday as part of the cleanup effort.

Department officials have determined the fungicide did not reach the Des Moines River.
