A proposed plan for a manure application has come under scrutiny for the potential harm it could cause in some of Iowa’s high quality waters.
Supreme Beef, a cattle company in northeastern Iowa, has applied to spread cow manure in a 30 mile area around their operation near Monona IA. Critics have warned that the plan may threaten water quality in the region, and pose a risk to the brown trout, a popular Iowa fishing attraction. The plan proposed by Supreme Beef has been targeted for the likelihood for manure overapplication as well as a failure to include required conservation practices.
The area where manure would be spread is close to the headwaters of Bloody Run Creek, an area where brown trout reproduce, which presents a threat to water quality because of northeastern Iowa’s karst topography. Karst topography is characterized by easy groundwater flow, which means that any manure seepage or contamination from the surface could easily influence the water quality of the region. Iowan’s in the area have needed to address similar issues previously, particularly for private well owners.
Currently the DNR is accepting written comments for the plan until March 8th before they will issue a decision for Supreme Beef’s manure application.
