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.
Phase II of the Burnham Creek Watershed Restoration Project will conduct inventory on 2,050 acres, 85.4 miles of ditch channel within the Burnham Creek Watershed of West Polk County. This inventory includes surveying, assembling all available GIS data, ArcMap, LiDAR, review aerial photography, location of tile intakes, determine size of the erosion sites, and prioritization of severity. The district will partner with the Area DNR Hydrologist and the Polk County Highway Department-Drainage & Ag Inspector to verify data and identify any additional ditch segments.
As part of the FY 2012 funding cycle, the Board of Water and Soil Resources granted funds for development of the Water Quality Decision Support Application (WQDSA). The WQDSA will provide land and water managers with geospatial data and online tools to prioritize, market, and implement actions on the landscape to achieve water quality objectives identified in local and state water plans and to ensure that public funding decisions are strategic and defensible.
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.
