The United States Environmental Protection Agency (USEPA) requires the Minnesota Pollution Control Agency (MPCA) to carry out the Total Maximum Daily Load Program (TMDL) in the state of Minnesota. Minnesota has an abundance of lakes and river reaches, many of which will require a TMDL study. In an effort to expedite the completion of TMDL projects, the MPCA has decided to construct watershed models. These models have the potential to support the simultaneous development of TMDL studies for multiple listings within a cataloging unit or 8-digit Hydrologic Unit Code watershed.
This project will monitor four lakes and 18 stream sites within the Yellow Medicine River Watershed to collect surface water quality data to determine the health of the watershed's streams and lakes and if they are in need of restoration or protection strategies. The sites will be monitored according to the Minnesota Pollution Control Agency's (MPCA) Water Monitoring Standard Operating Procedures.
The Yellow Medicine River Watershed District will contract with the Water Resource Center at the Minnesota State University - Mankato to complete a Geographic Information System (GIS) terrain analysis for the watershed using recently completed LIDAR data in southern Minnesota. Analysis will concentrate on the impaired reaches of the Yellow Medicine River Watershed and its tributaries. This inventory will utilize the State of Minnesota LiDAR elevation datasets to create many datasets through the analysis of this elevation data.
Over the years, the landscape of the Yellow Medicine Watershed has changed through drainage and loss of wetland areas. The Soil and Water Conservation Districts of Lincoln, Lyon and Yellow Medicine counties work cooperatively with the Yellow Medicine River Watershed District to oversee implementation of conservation practices in this watershed. Based on previous Clean Water Partnership diagnostic studies, it is known the river is receiving an excessive loading of nutrients, phosphorus and suspended solids. These conditions have led to declining dissolved oxygen levels as a result.
MNHS partners with diverse organizations to create in-depth, meaningful learning experiences for young people that help them develop career and life skills. The Mazinaakizige: American Indian Teen Photography Program welcomed six American Indian high school students who investigated historic and contemporary images of American Indians, learned digital photography, and created a gallery show to interpret the theme "Powerful." The opening was held at the Two Rivers Gallery on Dec. 9, 2016, with the gallery donating the space, announcement postcards and frames for the prints.

One example is the Mazinaakizige: American Indian Teen Photography Program.
Adoption of renewable energy technologies and energy conservation practices can contribute in a variety of ways to the environmental and economic health of rural Minnesota communities through costs savings and emissions reductions. Engaging and coaching students as the leaders in the process of implementing such practices provides the added benefit of increasing knowledge, teaching about potential career paths, and developing leadership experience.
In previous phases of work, a Hydrologic Simulation Program FORTRAN (HSPF) model of the Zumbro River Watershed was developed to simulate hydrology and water quality for the 1995-2009 simulation period (Phase I), applied to evaluate various management scenarios for reducing sediment and nutrient loading (Phase II), and used to develop Total Maximum Daily Loads (TMDLs) for impaired stream segments and inform development of a nutrient TMDL for Rice Lake (Phase III).
Olmsted Soil and Water Conservation District (SWCD) will work in coordination with Goodhue SWCD, Wabasha SWCD, and Dodge County Environmental Services to collect water quality and chemistry parameters on 23 MPCA approved sites within the Zumbro River watershed during the 2023-24 sampling season.
OVERALL PROJECT OUTCOME AND RESULTS This project identified and prioritized areas in the Zumbro River Watershed that were determined critical for restoring and protecting water quality. Studies suggested that small areas of the landscape contribute disproportionately to nonpoint source pollution. So implementation of conservation projects that focus on those areas will maximize water quality benefits and ensure efficient use of resources.
This project will build upon the outreach and education efforts of the Zumbro Watershed Restoration and Protection Strategy (WRAPS). The targeted area will be residents of the Zumbro River Watershed, specifically individuals and organizations that are not professionally involved in managing natural resources. This project will provide necessary outreach and education during the interim between the Zumbro WRAPS and beginning the One Watershed, One Plan process.
The goal of this project is to test the sensitivity of the Zumbro River Watershed Hydrological Simulation Program FORTRAN (HSPF) model management scenario results. Additional goals are to develop Total Maximum Daily Loads (TMDLs) for impaired stream reaches and Rice Lake, which will be documented in a TMDL Report. The consultant will apply the existing calibrated and validated Zumbro River Watershed HSPF model to construct load duration curves to develop TMDLs.
