This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
The Rum River is designated as a 'Wild and Scenic River' and is the major watershed in Mille Lacs County. Maintaining and protecting its water quality is a significant concern. The Clean Water Fund grant will result in the timely and successful implementation of ten nutrient management plans resulting in land management changes with an estimated average reduction of 30 pounds of Phosphorus and 40 pounds of Nitrogen per year on almost 2,000 acres.
Numerous studies have shown that stream bank erosion can be a significant contributor to the decline of water quality in the Rock River. The Clean Water dollars provided for this project assisted in three stream bank projects that address the turbidity (muddiness) impairment of the Rock River and bring the river closer to the level of water quality required for the EPA Clean Water Act.The $25,000.00 of Clean Water dollars were successful in leveraging $30,000 of US Fish and Wildlife funding as well as $20,000 of landowner and SWCD investment.
The purpose of the project is to reduce sediment and nutrient deposition in surface waters within priority areas of the watershed. A five percent reduction goal has been established in the County Local Water Management Plan and Impaired Waters project in progress. Eleven Best Management Practice (BMP) installations are planned for this project in cooperation with local landowners, Cities, Townships and Lake Associations.
