The Clay County Drainage Site is designed to evaluate the environmental impact of both surface and subsurface drainage from agricultural fields. This site includes six subsurface plots and one surface runoff plot, each approximately 24 acres in size. Monitoring stations are fully automated and each individual plot is monitored separately.The soils and topography across this demonstration site are virtually identical and represent field characteristics common in the most productive agricultural areas of the Red River Valley.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
The purpose of this project is to identify effective irrigation and nutrient management best management practices and technologies and the barriers that prevent irrigators, producers, and other agricultural partners from adopting them in Otter Tail County. The primary goal is to reduce nitrate in areas where groundwater is susceptible to contamination as mapped by The Minnesota Department of Health by identifying effective BMPs and addressing the barriers to their adoption.
The goal of this project is to establish load reduction requirements for impaired waters and to develop restoration strategies to improve water quality for impaired waters and protection strategies to maintain the quality of water for water bodies meeting standards.
This project will update sediment Total Maximum Daily Loads (TMDLs) for 60-64 impaired stream reaches and provide a final TMDL report. The report will address sediment and turbidity impaired streams in the Minnesota River Watershed. TMDLs will describe the impairment in each water body and water quality targets, and will include a discussion of pollutant sources, supporting report components that document assumptions and methodologies, and TMDL equations with completed load allocations, wasteload allocations, and margin of safety for each impairment.
The goal of this project is to refine the nutrient and algae simulation in the Minnesota River basin using all relevant available sources of information. The outcome of this work order is a revised Hydrological Simulation Program – FORTRAN (HSPF) watershed model application for the Minnesota River basin that correctly represents nutrient sources and algae.
The Otter Tail Water Management District (OTWMD) manages the wastewater for nearly 1,750 private residences near Otter Tail Lake, Deer Lake, and Lake Blanche. There OTWMD is responsible for 101 monitoring wells that were installed in 1984 and 1985 that are no longer being used and need to be properly sealed. The goal of this project is for the East Otter Tail Soil and Water Conservation District (EOTSWCD) to assist the OTWMD in properly sealing 100% of the monitoring wells that are located within the Otter Tail Surficial Aquifer.
The purpose of this project is to develop a detailed tool that can be used in all watersheds within the Otter Tail and Becker counties to prioritize, target, and measure implementation practices at the field scale. The PTM App will significantly increase the targeting capabilities in Otter Tail and Becker Counties. The Watershed Restoration and Protection Strategy has not been completed for Otter Tail County, yet, and the PTM App will be able to assist targeting and prioritizing when those documents are created.
The goal of this project is to complete the construction, calibration, and validation of a Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Otter Tail River watershed. The contractor will produce an HSPF model that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) Studies. The model will generate predicted output for hydrology, sediment, nutrients, and dissolved oxygen that is consistent with observed data.
This project will determine the condition of the water bodies in the Otter Tail River watershed, initiate public participation in the Watershed Restoration and Protection Strategy (WRAPS) development process, begin identification of potential stressors and priority management areas within the watershed, and begin development of initial drafts of the Total Maximum Daily Load (TMDL) study and WRAPS report.
This project will result in the development of three critical pieces of information. They include: 1. Development of restoration and protection strategies for all waterbodies in the district relative to the State's Non-point Source Funding plan 2. Use of PTMApp to tie the WRAPs implementation tables from the Buffalo and Red River Watersheds to targeted on-the-ground projects and practices that will provide measurable water quality improvements, and 3.
Realizing the need for increased technical capacity in the field offices, the Becker, East Otter Tail and West Otter Tail Soil and Water Conservation Districts have developed an agreement that will increase technical capacity while minimizing costs to each district. The first step was taken in this agreement through the recent hire of a shared engineer. Currently, minimal survey grade equipment is owned by the districts. This grant will be used to purchase an integrated survey system.
This goal of this project is the completion of a Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Upper Red River watershed in the Red River Basin. This includes the construction, calibration, and validation of the model for hydrology and water quality parameters.
This is a joint project between the United States Geological Survey (USGS), Minnesota Pollution Control Agency (MPCA), North Dakota, and Manitoba. The project is a basin-wide, up-to-date water quality trend analysis using the "QWTrend" program for approximately 40 bi-national river sites to review nutrients, total suspended solids, total dissolved solids, sulfate and chloride from 1980 - 2015.
