Iowa DNR is still looking for the source of a fish kill in the Backbone State Park

The Iowa DNR says its initial investigation into a fish kill Friday in Backbone State Park has been unable to determine a source of the problem.

DNR staff investigated the fish kill after trout anglers reported seeing dead fish in Richmond Springs and Fenchel Creek.  Staff members from DNR parks, environmental services and fisheries investigated over the weekend, but did not identify a pollutant source. They found dead trout and non-game fish, but also saw numerous live fish in several sections of the streams.

 
The DNR says it will continue to look for the cause of the partial fish kill.  It also praised the prompt reporting by trout anglers, which meant investigators could quickly look for a pollutant source.
