Six-mile oil spill on Mississippi River headed for La Crosse

A 6-mile oil slick is working its way down the Mississippi River and is expected to reach La Crosse by 5 p.m. today.
At least 1,000 gallons of diesel appears to have entered the river upstream of Dakota, Minn., according to the Wisconsin Department of Natural Resources.
The source of the oil is unknown, but the U.S. Coast Guard does not suspect a boat.
The oil is not a threat to aquatic life, but the DNR advises people to avoid contact. The agency says to expect the smell to linger through Friday.
The oil is not recoverable and is being dispersed by swift currents, according to the DNR.
DNR spokesman Ed Culhane urged concerned citizens not to clog 911 lines with calls about the slick.
The Minnesota Pollution Control Agency is heading the investigation into the source, Culhane said.
