06001-001 Norfolk Creek Watershed Final Report

This project would target Norfolk Creek Subwatershed for land treatment practices. The Norfolk Creek Subwatershed is 14,035 acres located southwest of Waukon. The landscape is characterized by rugged karst topography and is marked with hundreds of sinkholes, providing direct drainage into the water table, affecting wells, springs, and community water sources. The surface groundwater runoff from this karst landscape eventually flows into the Yellow River. The potential point and non-point pollution sources are complicated and expensive to resolve. Extensive water quality monitoring has been completed on Norfolk Creek and has tested high in many parameters. We hope that with the upland treatment included in this grant request, terraces, grade stabilization structures, sediment control basins, and livestock manure management systems, these will improve. Continued water quality sampling will monitor this. This application has been reviewed and approved by the Allamakee County Soil and Water Conservation District Commissioners.
