Officials investigated manure runoff that reached Storm Lake and are considering enforcement action.
The Iowa Department of Natural Resources said that staff found elevated ammonia levels near the shoreline after receiving a complaint. Due to ice covering the lake, they were unable to determine if there was a fish kill.
The runoff was traced to the fields at Don Jackson’s Pike Farms cattle feedlot of Storm Lake, according to a release from the DNR.
They said that solid manure was applied to the field had runoff that travell half-a-mile into South Cove and a quarter-mile east of South Cove Park. Jackson reportedly told the DNR that for three days, including during Wednesday’s rain, he applied dry manure. The then agree to stop applying the manure, holding it until conditions improve.
DNR will follow up and consider appropriate enforcement action.
The DNR said they receive many calls during heavy rainfall and flooding. They say that any livestock producers should contact their local field office to discuss manure-related issues. After business hours, they should call the emergency line at 515-725-8694.
