The DNR is asking farmers to use extra caution when applying manure right now.
Last week, a manure runoff led to a fish kill in Dubuque County. Investigators say the owners of Lawler Dairy Farm in Peosta applied liquid manure to a nearby field – but due to snowmelt and rainfall, the manure ran into a nearby ravine and through a tile intake into an unnamed tributary located along Graff Road north of Peosta.
The manure runoff reportedly killed over 230 fish.
DNR environmental specialist Brett Meyers says the weather conditions have not made it easy for spreading manure.
Meyers says if they had been able to inject the manure into the ground, it would not have been as big of a problem. He advises anyone with a livestock operation to be sure they properly assess the situation before applying any manure to avoid runoff.
The DNR will decide if any enforcement action is needed against the operation once it completes its investigation.
