Red Lake County SWCD will continue to work cooperatively with the Red Lake County Ditch Authority, and the landowners involved to reduce erosion and sedimentation, reduce peak flows and flooding, improve water quality, and protect drainage system efficiency for priority Chapter 103E drainage systems by installing thirty-seven multipurpose drainage management practices. The priority Chapter 103E drainage system is Judicial County Ditch 60.
The Red Lake River from County Ditch 96 (Pennington County) to where the Clearwater River enters the Red Lake River (Red Lake Falls) is on the TMDL Impaired Waters List for Turbidity. This reach is a high priority because of the high importance of the Red Lake River, which provides a domestic supply use of the water source and provides abundant recreational uses.
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 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 improve understanding of primary productivity in the Red River and the diversity and population structure of the algal communities occurring along the river system. This will be accomplished through taxonomic identification of periphyton and phytoplankton assemblages necessary for characterizing responses to nutrient gradients along the Red River of the North.
