Lake Minnewaska, a highly used recreational lake, is the largest body of water in Pope County. While scientific studies show that the transparency in Lake Minnewaska has been increasing over the last 30 years, there are numerous ravines on the south shore of Lake Minnewaska that could threaten this trend. The erosion in these ravines is causing large amounts of sediment and phosphorus to be dumped directly into Lake Minnewaska. After a storm in 2011, many trees vegetating the ravines were blown down, ripping out the roots and further exposing the soil along these ravines.
The Two Rivers Watershed is listed as a high priority in the Stearns County Comprehensive Water Management Plan. This project will inventory the existing public drainage systems and develop a targeting program to measure, prioritize and target the factors causing the water quality problems of Two Rivers Lake (impaired for nutrients) in Stearns County. With public access and a county park on the lake, it is a destination for fisherman in the area.
The North Fork Crow River Watershed District will develop an inventory and 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 throughout the district. This software will be used to facilitate statutory compliance including developing a process for completing annual inspection and reporting requirements.
The Le Sueur Soil and Water Conservation District (SWCD), who acts as County Ditch Inspectors, will partner with the Le Sueur County GIS Coordinator to accomplish the inventory and inspection of drainage ditches. A database will be established for all 250 miles of Le Sueur County Drainage Authority ditches. The inventory will be conducted using Lidar, 2010 and 2013 Pictometry and onsite technical review. Sites that have potential water quality issues will be identified from worst to most stable for side inlets, buffers and retention storage.
Eight towns in Martin County recently updated their wellhead protection plans. One of the main protection plan items is to seal abandoned wells within the towns' Drinking Water Source Management Areas. This project will provide 50% cost share, up to $1,000, to help offset the cost of sealing abandoned wells.
Dakota County is partnering with the Dakota Soil and Water Conservation District to preserve and enhance the chain of shallow lakes in Lebanon Hills Regional Park which is owned and operated by Dakota County and located within the City of Eagan. Dakota County proposes to construct two regional iron-enhanced sand filtration practices to achieve the load reduction goals set forth in the LHRP Subwatershed Assessment Report to protect Jensen and Schulze lakes and prevent them from being listed on the 303(d) Impaired Waters List. The project will reduce 26 pound of phosphorus annually.
The City of Minnetonka and its residents highly value the water resources within the community, which include approximately ten lakes, four streams, and hundreds of wetlands. The City has been progressive in protecting these resources through policies and management strategies, and now wants to increase their on-the-ground efforts in protecting and improving water quality. The City hopes to conduct targeted watershed assessments for fourteen selected priority water bodies to identify and optimize the type and locations of Best Management Practices (BMPs) to be installed.
This project will protect the groundwater and the city of Princeton's drinking water from nutrient contamination associated with livestock manure storage. Well water tested throughout Mille Lacs County, and specifically within the Anoka Sand Plain area of Princeton, routinely indicate the presence of nitrates in shallow drinking water wells.
