Net River Watershed Sediment Reduction Project - Stormwater and the Road Stream Interface
The Nemadji Watershed is characterized by its red clay soils and steep slopes, with streambanks that are prone to slumping and erosion and is a major contributor of sediment and phosphorous into Lake Superior. Our project works towards targeting erosion on the Little Net River, a tributary to the Nemadji River and a high-quality trout stream. An undersized culvert was recently completed to improve fish passage to over six miles of stream, but stormwater runoff near the bridge has contributed to a major gully formation upstream of the bridge project, resulting in contributions of 3,517 tons of sediment and 4,045 pounds of phosphorous per year. Our project will address the stormwater runoff and stabilize the failing bank based on recommendations from geotechnical and stormwater engineers. It will also protect the stream bank using fish passage friendly designs. The result will be reduced sediment and phosphorus to the Little Net River, protection of the valuable trout resource and improved public safety.

(Projects and Practices)(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.
Our project will reduce an estimated 3,517.5 tons of Sediment (TSS) and 4,045.13 pounds of phosphorous per year using the BWSR Erosion Pollution Reduction Estimator.
This project has resulted in an estimated annual reduction of 424 lbs of Phosphorus, 424 tons of Soil Loss,
