Appropriation Language

(a) $13,750,000 the first year and $13,750,000 the second year are for pollution reduction and restoration grants to local government units and joint powers organizations of local government units to protect 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 (SSTS) projects and stream bank, stream channel, and shoreline restoration projects. The projects must be of long-lasting public benefit, include a match, and be consistent with TMDL implementation plans or local water management plans.

Project Overview

The Thief River and its tributaries have deteriorating water quality due to sedimentation. Sediment plumes and deltas have formed at the inlets of pools in Agassiz National Wildlife Refuge (Agassiz Pool) and Thief Lake, an important recreational resource in Northwest Minnesota.
Radioisotope soil fingerprinting indicates the severity of the sedimentation problem is within Agassiz Pool. It is estimated that 14,900 tons of sediment has been deposited in Agassiz Pool annually, since 1938. The fingerprinting analysis indicates the dominant source of this sediment is erosion of uplands and fields.
This project is a collaborative partnership with USDA-NRCS to establish 50 ft. wide native grassed filter strips, grade-stabilization structures, and field windbreaks to prevent or reduce sedimentation problems. This effort will stabilize the soil, slow down water runoff, and filter the water before entering ditches and streams. The goal is to establish 16 miles of grassed filter strips, 5 miles of field windbreaks, and install 25 grade stabilization structures where needed. Targeted areas within the Thief River Watershed have been prioritized through analysis of sub-basin sediment yields generated by a Soil and Water Assessment Tool model of the watershed. The model estimates that these practices can reduce sediment loads by more than 1,500 tons/year.
