The Iowa Department of Natural Resources is investigating a manure spill that caused a fish kill on Wolf Creek in Tama County.
A manure applicator from Mayo Farm Inc., of Garwin, reported Thursday morning a drag hose leaked about 2,600 gallons of manure during land application, the DNR reported Friday.
The applicator built a berm to dam up the spilled manure but estimates up to 500 gallons reached the creek.
DNR staff found some dead fish about a mile to 1.5 miles downstream Friday.
DNR fisheries staff were scheduled to be on site Friday afternoon to determine the extent of the fish kill 2 miles northwest of Vining.
DNR will monitor cleanup activities and consider appropriate enforcement action.
