A fish kill is being investigated in north-central Iowa. Officials with the Iowa Department of Natural Resources say they’re looking into a fish kill that was reported along Bailey Creek southeast of Thornton in Cerro Gordo County.

They’re working to identify the cause of the spill, which has spread at least three miles downstream. Minnows, suckers and game fish like northern pike were found dead in the creek – which is a tributary of the West Fork of the Cedar River.

D.N.R. staff has collected water samples and will conduct a fish count later today.
