The City of Myrtle is an unsewered community in Freeborn County. Thirty-one of thirty-two properties are connected to a community straight pipe, which discharges raw sewage into Deer Creek, a tributary of the Cedar River and are classified as an imminent threat to public health (ITPHS). This project will provide cost-share assistance to 28 low income property owners, who are connected to the City of Myrtle community straight pipe, for construction of individual subsurface sewage treatment systems.
County Ditch #8 (CD8) has been identified as an area of high erosion by the Freeborn County Drainage Authority and the Turtle Creek Watershed district. Project entails using conservation BMPs such as water and sediment control basins, grassed waterways, and alternative tile intakes to address gully and sheet and rill erosion concerns at the headwaters of CD8.
In the battle to make real progress in sediment reduction to Turtle Creek, buffer strips are on the defensive front lines, holding the land at its most critical point. Grass strips along waterways have long provided a catchment area for agricultural field runoff. The Conservation Reserve Program (CRP) has developed guidance and performance standards that utilize the maximum amount of benefit when installed through that program. In recent years, the Turtle Creek Watershed residents have faced a difficult decision over whether or not to incorporate grass buffers on their farms.
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.
Nicollet County is located in south central Minnesota and is bordered on two sides by the Minnesota River. A line of forested bluffs separate the river valley from land that is relatively flat and historically used for agricultural purposes. Approximately 245,000 acres of the County are actively farmed. The 2012 impaired waters list for water bodies located in Nicollet County include the Minnesota River, Seven Mile Creek, Rogers Creek and tributaries to the Rush River.
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 lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these small communities will receive technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly to the environment, surfacing sewage, or have sewage contaminating groundwater.
This project will assure that buffer strip compliance is being followed throughout the system. It will identify areas that will work to keep excess sediment and nutrients out of the water and provide a good strategy for cleaning the water and reducing costs to the system long term. More importantly, it provides an opportunity to have dialogue with landowners along the entire ditch and communicate the importance of buffers and conservation practices such as detainment areas and catchment Best Management Practices that keep the soil out of the system.
