-Sny Magill Creek is a cold water stream in Clayton County in northeast Iowa. It is managed for “put and take” trout fishing. A USDA Hydrologic Unit Area (HUA) project was initiated in the 22,780-acre watershed in 1991. Over $3.1 million has been allocated for watershed protection and monitoring from state and federal programs.
-There are over 10,000 acres of Highly Erodible Land is the watershed, including most cropland and some pastures. The multi-agency project, which involves NRCS, Iowa State University Extension and many other partners, provides technical assistance, information and education, and cost-share assistance to help producers implement their conservation plans and make additional voluntary changes in farm management practices to protect water quality. A 10-year US EPA 319 water quality monitoring program is being conducted under the leadership of the DNR-GSB in association with the Sny Magill HUA project. The adjacent Bloody Run Creek serves as the paired watershed for the monitoring protocol.
-Sny Magill Creek is one of the more widely used streams for recreational trout fishing in Iowa.
-The watershed is characterized by narrow, gently sloping uplands that break into steep slopes with abundant rock outcrops. Up to 550 feet of relief occurs across the watershed. The stream bottom of Sny Magill and its tributaries is primarily bedrock and gravel with frequent riffle areas. Along the lower reach of the creek where the gradient is less steep, the stream bottom is generally silty. Sny Magill Creek empties into the backwater wetlands of the Upper Mississippi River Wildlife and Fish Refuge and part of Effigy Mounds National Monument.
-Eighty-one percent of the watershed’s 98 landowners have participated in the project.
-Pesticide and nutrient loading have been reduced on 45% of cropland acres in the watershed through the delivery of nutrient and pest management assistance and education programs by ISU Extension.
-The NRCS estimates that structures and crop management best management practices (BMPs) have reduced sediment delivery to the stream over 50%, 35,031 T/yr, compared to pre-project practices.
-Streambank bioengineering practices established by the project have become a laboratory for study of innovative, lower-cost stream protection measures in Iowa.
Integrated Crop Management (ICM) methods are being used to assist producers with the adoption of refined crop-management practices. A project coordinator served as a crop consultant and hired a crop scout to make field observations. This activity resulted in 39,450 pounds less nitrogen, 33,625 pounds less phosphate, 128 pounds less alachlor (herbicide) and 1,450 pounds less corn rootworm insecticide being applied annually in the watershed. The cost savings to the producers involved with the ICM activity is averaging $13.85 per acre per year.
The Nutrient and Pest Management Incentive Education program (NPMI) was a local initiative of the Northeast Iowa Demonstration and Sny Magill project, which were served by the same extension NPM specialist. The program provided NPM assistance with a specific educational component, to enhance long-term adoption of refined crop and manure management practices. Participants used their own farm records to learn to write and evaluate NPM plans over a 3 year period.
-Affordable streambank protection
-Increased profitability
