JEFFERSON (AP) — Authorities are trying to find the source of a fish kill in a central Iowa creek.
The Iowa Natural Resources Department said in a news release Wednesday that U.S. Agricultural Department employees sampling a stream noticed the dead fish in Hardin Creek, about 2 miles east of Jefferson in Greene County. It’s uncertain how many fish have died.
The Iowa department says the affected area is at least 3 miles long. The department also says residents should keep children and pets out of the stream for 24 to 48 hours after the pollutant is gone.
