Watershed Des Moines Achievements and Missouri River Report Basins 2008 Watershed Achievements Report Statewide 2015 Des Moines Headwaters Heron Lake Sediment Reduction Demonstration Project Flooding is a major problem along creeks in the Heron Lake Watershed District (HLWD). Cropland and township roads are being threatened by streambank erosion. Project partners implemented the installation and demonstration of two sediment reduction techniques that are new to southwestern Minnesota, tree revetments and J-hook weirs. Both of these practices have documented success in other parts of the country. Limited information was available regarding use of these techniques in southwestern Minnesota. A common streambank erosion control method is riprap, which is expensive and does not truly solve the problem. Cedar revetments and J-hook weirs are natural, effective, relatively inexpensive, and easily implemented. Benefits include streambank erosion control, restoration, and stabilization, sediment and phosphorus reduction, habitat gain, and improved water quality. In order to see a change on the landscape, educational efforts must be undertaken. Project partners believe that providing watershed landowners with demonstration of streambank stabilization practices and their economic and environmental benefits will produce long-term water quality benefits for the watershed. Successful implementation of these demonstration practices could lead to cost-share or incentive programs from the HLWD. Goals • To install and demonstrate a cedar revetment and a J-hook weir at two locations in the Heron Lake watershed. • To provide educational opportunities through two tours and inform the public about the project through four newspaper articles and newsletters and four meeting updates to each of the four counties. • To provide digital documentation for use on the website and in presentations that illustrates structure capability and success through video footage and photographs before, during, and after installation. Results that count • One cedar revetment and one J-hook weir were installed. • Two tours were held that provided direct contact with 50 people. Two newspaper articles, three newsletters, and 19 updates were given at HLWD and county board meetings. • A webpage was created and contains video footage and photographs, as well as promotional materials.
