2020 Crow River Gully Stabilization to Reduce Turbidity Phase Four
The Wright Soil and Water Conservation District has partnered with the Natural Resources Conservation Service (NRCS) on phase four of this comprehensive sediment reduction project to focus on stabilizing seven of the most active gully erosion sites in the targeted DNR 12 digit HUCs 070102040602, 070102040603, 070102040604 and 070102040605 on the North Fork Crow River, as well as use the installed best management practices (BMPs) to help promote future conservation practices. The first three phases have been very successful in terms of landowner interest and strong partnerships with NRCS leading to more matching cost share dollars than anticipated, resulting in additional projects. In total, 34 water and sediment control basins and 17 grade stabilization structures have been installed using $324,579.79 in CWF grants while also leveraging $239,653.08 through NRCS's Environmental Quality Incentives Program (EQIP) and $87,587.42 in landowner match. A LiDAR study and follow-up field inspections were done on a number of gully sites within the aforementioned HUCs and 15 priority sites were identified. These particular HUCs were chosen due to the high level of turbidity and low dissolved oxygen within that stretch of the North Fork Crow River, which has led to biological and turbidity impairments. This project will drastically reduce the amount of sediment and phosphorus being exported from the targeted stretch of the Crow River by constructing BMPs, including grade stabilization structures and water and sediment control basins, at the headward eroding extent of these gullies. The installed BMPs will stop the gullies' advancement and thus help to heal the lower stretch over time. This project is targeting the western half of the North Fork Crow River in Wright County, after the first three phases of the project focused on a similar area with great success and will be using the original BMP sites as examples for future potential project landowners.
[Projects and Practices 2020] (b) $16,000,000 the first year and $16,000,000 the second year are for grants to local government units to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of this money may be used to seek administrative efficiencies through shared resources by multiple local governmental units. Up to 20 percent of this appropriation is available for land-treatment projects and practices that benefit drinking water.
This grant's anticipated measurable outcomes are a reduction of 210 tons of sediment per year and 280 pounds of phosphorus per year. Over the ten-year minimum lifespan of these projects, that is less than $100 per pound of phosphorus.
