A diesel fuel spill earlier in the week near Iowa Falls is almost cleaned up, according to the DNR.

The 50 gallons of fuel reached the South Fork of the Iowa River after a shutoff valve on an Agvantage FS truck was refueling a farm tank.

The spill was contained to just south of Highway D41 to about 0.75 miles west of KK Avenue.

DNR will continue to monitor cleanup.
