GARNAVILLO, Iowa (AP) — The Iowa Department of Natural Resources is investigating a major manure spill in eastern Clayton County.
The department says between 50,000 and 70,000 gallons of manure flowed at 800 gallons a minute out of a broken pipeline March 10 at dairy farm north of Garnavillo. Much of the manure overflowed from a concrete basin and eventually flowed into Buck Creek.
The dairy dammed up the spill to stop manure from flowing.
The DNR is investigating if the spill caused a fish kill in Buck Creek.
