The Pennington SWCD has collaborated with Pennington County for several years to identify priority County Ditch reaches that are in need of buffers and grade stabilization structures. This cooperative effort has resulted in the reduction of nutrient and sediment delivery to the Red Lake River Watershed. Pennington SWCD has recently inventoried buffer and grade stabilization needs on three different County Ditch systems: 96, 21 and 16. A total of 23 miles of ditch has been inventoried, 15 miles of buffer are needed along with 81 grade stabilization structures.
Sediment and water quality issues are local priorities within the Thief River and Red Lake River watersheds, which have their confluence in the city of Thief River Falls. The 1W1P effort underway in the Red Lake River Watershed will identify opportunities for projects and practices that are targeted and result in measurable water quality benefits throughout the watershed using PTMApp.
The goal of the Pomme de Terre River Association (PDTRA JPB) is to improve the local water resources within the watershed through targeted voluntary efforts and the building of strong relationships with local landowners, producers, and citizens. To further our efforts in strategically working to achieve our reduction goals, listed in our Major Watershed Restoration and Protection Strategies Report and Turbidity Total Maximum Daily Load report, we would like to further define our Priority Management Zones through the development of a hydrological conditioned Digital Elevation Model.
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.
Spring Park watershed is over 225 acres. Most of the watershed has been fully developed into a variety of residential, commercial, and institutional land uses. Project funds would be utilized to conduct a watershed analysis with the goal of identifying pollutant load sources and potential areas for structural stormwater BMPs for future retro-fit projects to reduce instances of localized flooding, reduce peak storm flows, and improve the quality of stormwater runoff discharging into Crocker's Creek.
To be able to manage resources in the Blue Earth and Le Sueur Watersheds into the future and have a positive effect on water quality, resource managers need high quality accurate data to support decision making of best management practice (BMP) implementation. Digital elevation data is a valuable resource for modeling water flow, however in its current state it cannot represent water conveyance through features such as roadways. These flow barriers limit the accurate use of data for recently developed targeting tools identifying BMP suitability and effectiveness down to the field scale.
With the completion of LiDAR data in southern Minnesota, it is imperative to use this data as effectively as possible. In order to do so, the Greater Blue Earth River Basin Alliance (GBERBA) will contract with a vendor to complete a Geographic Information System (GIS) terrain analysis in subsheds of the Watonwan River watershed. This inventory will utilize the State of Minnesota LiDAR elevation datasets to create many GIS datasets by spatially analyzing the elevation data.
