NEW VIENNA, Iowa — Authorities are blaming a manure runoff from a dairy farm for killing about 60,000 fish in eastern Iowa.

The farm is situated about 3 miles (5 kilometers) east of New Vienna. The fish kill was reported Oct. 9 after fish carcasses were spotted in two creeks downstream in Dyersville.

The Iowa Natural Resources Department has issued a notice of violation to the owner, John Hoefler, and is expected to seek restitution for the fish. Among the dead were minnows, white suckers and creek chubs.
