These funds are being used to systematically collect data and produce statistically valid estimates of the rate of soil erosion and tracking the adoption of high residue cropping systems in in the 67 counties with greater than 30% land in agricultural row crop production. Designed to establish a long term program in Minnesota to collect data and produce county, watershed, and state wide estimates of soil erosion caused by water and wind along with tracking adoption of conservation measures to address erosion.

The goal of this project is to address public comments on the public noticed draft Watershed Restoration & Protection Strategy (WRAPS) study and Total Maximum Daily Load (TMDL) report for the watershed, and to produce a final draft WRAPS study and TMDL report ready for final approval by the United States Environmental Protection Agency (USEPA) and Minnesota Pollution Control Agency (MPCA).
Funding supports an Irrigation Specialist to develop guidance and provide education on irrigation and nitrogenbest management practices (BMPs). In this position, Dr. Vasu Sharma provides direct support to irrigators onissues of irrigation scheduling and soil water monitoring. She is collaborating on the development of new irrigationscheduling tools that help irrigators manage water and nitrogen resources more precisely. These tools help reducenitrogen leaching losses in irrigated cropping systems.
The Otter Tail River is located in west-central Minnesota. Its Lower Otter Tail River (LOTR) reach is impaired for sediment. The LOTR begins at the dam of Orwell Reservoir near Fergus Falls and ends 48 river miles downstream at the confluence with the Bois de Sioux River at Breckenridge. No point sources contribute directly to the LOTR. Consequently, the turbidity impairment must be addressed through non-point measures. Current stream instability and bank erosion is largely a result of an 18-mile channel straightening completed by the Army Corps of Engineers in the 1950s.
This restoration and protection project will reduce the loading of sediment to the Otter Tail River by 440 tons/year. This is about 6.5% of the total reduction needed to meet the goals of the Lower Otter Tail TMDL Implementation Plan. The Otter Tail River downstream of Orwell Dam is impaired due to sediment, with stream bank erosion being the primary contributor. This stream bank restoration will include the installation of woody toe debris benches and the installation of a vegetated slope along a 1,400 foot reach of the river.
The goal of this project is to construct, calibrate, and validate a Hydrologic Simulation Program FORTRAN (HSPF) watershed model for the Otter Tail watershed. The contractor will produce a HSPF watershed model application(s) that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs). The contractor will clearly demonstrate that this model generates predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
The Otter Tail River is impaired for turbidity. This project involves the installation of 45 side-inlet structures into Wilkin County Ditch 3-2 and 7-1 and 22 acres of buffer strips along the entire systems. Eleven miles of continuous berm will also be constructed along the ditch. When installed these water quality practices will become a permanent part of the ditch system and will be maintained by the ditch authority. These ditches outlet to the Otter Tail River just upstream from Breckenridge, MN. Together these water quality BMPs will reduce sediment loading by 1,375 tons/year.
This project is for Minnesota Legislative Clean Water Fund funding to engage citizens in local watershed monitoring, to work with regional partners to promote understanding and protection of watersheds, and to organize and facilitate gathering of scientific data all for the benefit of water quality in the Red River Basin.
The International Water Institute (IWI) will monitor 42 sites (3 basin, 12 major watershed, and 27 subwatershed) in the Red River and Upper Mississippi River Basins intensively during the contract period. There will also be 5 sites in the Red River Basin where mercury samples will be collected and sent to Minnesota Department of Health for analysis. The IWI will collect water samples across the range of flow conditions targeting sample collection at times of moderate to high flow.
The purpose of this project is to improve understanding of primary productivity in the Red River and the diversity and population structure of the algal communities occurring along the river system. This will be accomplished through taxonomic identification of periphyton and phytoplankton assemblages necessary for characterizing responses to nutrient gradients along the Red River of the North.
The Whiskey Creek Watershed is the largest subwatershed in the Upper Red River of the North drainage, encompassing 165.63 square miles in Otter Tail and Wilkin Counties. This watershed contains the headwaters of the Red River of the North, which begins in far west central Wilkin County, an area of mixed residential and agricultural land use. The cities of Breckenridge, Minnesota and Wahpeton, North Dakota, as well as the small town of Kent are within the watershed.
