The City of Thief River Falls drinking water is taken from a 135 acre reservoir that is supplied by the Thief River and Red Lake River. Sedimentation and erosion have significant impacts to the waters in Pennington County. The reservoir is filling with sediment faster than expected. Buffers and side water inlets will help reduce sediment and improve water quality for these types of erosion. Buffers would also reduce nutrients polluting the waters in Pennington County and have a beneficial impact to the dissolved oxygen impairment on both the Red Lake and Thief River.
The Accelerated Water Quality Project Implementation Program will increase the connection between landowners, local government units and the landscape to accelerate efforts addressing non-point source loading to surface waters throughout the Red River Valley Conservation Service Area.
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.
Numerous County ditch systems in Pennington County end at a natural drainage prior to outleting into a river or other watercourse and these outlets can be in a very erosive state. The goal of this project is to inventory these systems to determine needs and prioritize projects for implementation.
The purpose of this project is to identify effective irrigation and nutrient management best management practices and technologies and the barriers that prevent irrigators, producers, and other agricultural partners from adopting them in Otter Tail County. The primary goal is to reduce nitrate in areas where groundwater is susceptible to contamination as mapped by The Minnesota Department of Health by identifying effective BMPs and addressing the barriers to their adoption.
The Red Lake Watershed District will create an inspection database for 103E ditches under their drainage authority. The district will acquire a database software solution to conduct field inspections and to track ditch maintenance projects and use the software to facilitate compliance with state statutes. The project will also develop a process for completing the annual inspection and reporting requirements under Statue 103E.
