Roseau River Water Quality project

Roseau River Watershed District (RRWD) is initiating a water quality improvement project to reduce sediment contribution from the Watershed Ditch 4 (WD 4) subwatershed. WD 4 outlets into the Roseau River which is the resource of concern we will help protect with this project. The Roseau River is utilized for many recreational purposes including bird watching, boating/paddling and fishing. River habitat protection is a priority for the District and projects like this are an excellent step in that direction.
The RRWD in cooperation with landowners, road authorities, and the Roseau SWCD will implement conservation practices on 30 priority sites targeted due to the large volume of sediment they contribute to the river. Twenty-nine SWIs and one rock grade control structure were identified through the Prioritize Target Measure Application (PTMApp) as priority concerns, needing protection from chronic erosion.
The PTMApp toolbar estimates the 29 Side Water Inlet sites identified contribute 62.46 tons of sediment annually into the Roseau River. The rock grade control structure is located at the confluence of WD 4 and the Roseau River. This location currently contributes 7.9 tons of sediment annually into SD51 in accordance with the PTMApp toolbar. The annual sediment yield estimates for the target subwatershed is between 89 - 178 tons, according the draft WRAPS report for the Roseau River Watershed. The PTMApp desktop identified 399.7 tons of annual sediment yield from the target subwatershed. Each of the identified sites constructed would be 410 grade stabilization structures preventing future head cutting and sediment deposition into the river. The overall budget for this phase of the project is $200,013. Estimated costs consist of engineering, construction, and administrative costs associated with all 30 sites.
