The Faribault Soil and Water Conservation District will provide mini-grants to conservation-conscious community organizations who voluntarily construct best management practices that provide storage and treatment of stormwater runoff at its source.
The purpose of this project is to complete Intensive Hydraulic Conditioning on the remaining 60% of the watershed to be able to utilize the Prioritize, Target, and Measure application (PTMApp). The basin has 1.1 million acres of drainage with approximately 630,000 acres remaining to be hydro conditioned. With the advancement in targeting pollution sources within the watershed and state, the partners intend to be able to more accurately target conservation practices with the hydraulic conditioning completed.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
Regionally, nitrate nitrogen concentrations are continuing to increase in both surface water and ground water based on monitoring data. The increasing trends are thought to be attributable to over application of manure and commercial nutrients on row-cropped fields. In order for nitrate concentrations to decrease, nutrient management is needed throughout the basin. Two nutrient management specialists will assist landowners in the eleven-county Southeast Minnesota Area with writing nutrient management plans and implementing conservation practices for manure and fertilizer use.
Lake Okabena does not meet state water quality standards due to high phosphorus levels. The Total Daily Maximum Load Study identified a 70% reduction in phosphorus from the watershed is needed to meet water quality standards. The City of Worthington owns the recently closed Prairie View Golf Course. Okabena Creek flows through the golf course and some small ponds. This project will modify these three ponds to increase storage and removal efficiency, and add an iron-enhanced filter bench to enhance soluble phosphorus removal.
The lack of sewage treatment in some small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes discharging raw sewage directly into the environment;surfacing sewage or have sewage contaminating groundwater.
The lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Ten of these small communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly into the environment, surfacing sewage, or have sewage contaminating groundwater.

The Yellow Medicine One Watershed One Plan has identified Protecting and Preserving Groundwater Quality and Quantity as one of the three priorities addressed in the Plan. Seven priority sub-watersheds have been identified as priority areas, as well as two townships that have been identified by the Department of Agriculture to have vulnerable groundwater areas. Our goal is to provide 50% cost share to seal 34 abandoned wells that are located in these priority areas.
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.
