JEFFERSON, Iowa — The Iowa Department of Natural Resources announced about 5 p.m. Wednesday it is investigating a fish kill in Hardin Creek about two miles east of Jefferson in Greene County.
Staff members at the local U.S. Department of Agriculture service center noticed the dead fish while stream sampling in the area, a DNR statement said.
The DNR said it has little information at this time on the source and extent of the fish kill but is investigating onsite.
The fish differ in size and species, the statement said, and the affected area is at least three miles long.
Downstream livestock producers might want to consider using another water source for their animals until the pollutant has been identified.
Residents should keep children and pets out of the stream for 24 to 48 hours after the pollutant is gone.
The DNR said anyone seeing a fish kill or an obvious pollutant should notify the local field office or call the 24-hour DNR spill line at 515-725-8694. The earlier the DNR is notified, the easier it is to trace the pollutant to its source.
