DUNLAP, Iowa – The Iowa Department of Natural Resources (DNR) is investigating a release to the Boyer River from a stormwater ditch in Crawford County. On Wednesday morning, Aug. 6, 2025, the DNR Atlantic Field Office was contacted about a release to the Boyer River from a structure fire at Rockin K Solutions near the intersection of Highway 30 and County Road 37 in Dunlap.

The fire destroyed a service station and resulted in the release of up to 1,200 gallons of fuels, oils, aerosols and other products. Much of the release was consumed in the fire. An unknown amount of product entered a storm drain, where it then flowed into a stormwater ditch to the Boyer River. No immediate impact to aquatic life was observed.

DNR field office staff are on-site investigating the release.
