FY22 CWF Ravenna Trail Ravine Stabilization
Portions of the lower Vermillion River are abutted by steep, erodible hillsides that deposit sediment directly in the river during rain events and contribute to this reach of the Vermillion River being impaired for turbidity. The Vermillion River Watershed Joint Powers Organization (VRWJPO), in partnership with Dakota County and the Dakota Soil and Water Conservation District, seeks to complete stabilization of two heavily eroded ravines that have repeatedly deposited sediment in the Vermillion River adjacent to Ravenna Trail (County Road 54) through the installation of armoring/rock-lined channel, ravine bank and channel stabilization, low-flow drop structures, riprap check dams and plunge pools, and other practices across 3,600 linear feet of ravine. Addressing this erosion will have an estimated pollutant reduction of 130 tons per year of total suspended solids (TSS) and 78 pounds per year total phosphorus (TP).

(Projects and Practices)(b) $10,762,000 the first year and $11,504,000 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. Up to 20 percent of this appropriation is available for land-treatment projects and practices that benefit drinking water.
The measurable outcomes for the project are a reduction in total suspended solids (TSS) of 130 tons per year and a reduction in total phosphorus (TP) of 78 pounds per year.
