This project proposes the implementation of 10 best management practices identified as having the lowest cost-benefit ratio as it relates to phosphorus reduction to downstream Moody and Bone Lakes with an estimated reduction to watershed phosphorus loads to Bone Lake by 90 pounds per year and to Moody Lake by 24 pounds per year. The Bone Lake watershed is at the ?top? of the larger watershed, making it an ideal location to begin work that will have direct improvements downstream.
This project will provide cost-share funds to landowners in vulnerable groundwater areas for the incorporation of cover crops in their crop rotation and to provide education related to nitrogen BMPs through field trials and Nutrient Management Plans. An anticipated 100 producers in highly vulnerable areas, will plant 3,000 acres of cover crops resulting in preventing potentially 19,800 pounds of nitrate from leaching into groundwater.
This project proposes to address the largest phosphorus loads discharging from 885 acres to Lake St. Croix through the installation of targeted stormwater treatment best management practices ranked in the top 10 of those prioritized in the 2018 Lake St. Croix Direct Discharge South Stormwater Retrofit Analysis. The goal of this project is to reduce pollutant loading from four small communities to Lake St. Croix by at least ten pounds phosphorous.
It is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications. The Metro Conservation District?s (MCD) Sub-Watershed Analysis (SWA) program provides these capacity-building services and unites efforts across 11 SWCDs. MCD proposes to analyze an additional 15 subwatersheds. The analyses will identify the location and estimated cost/benefit relationship for BMPs, evolve with new technology, and share discoveries metro-wide.
The Minnesota Ag Water Quality Certification Program (MAWQCP) is a voluntary opportunity for farmers and agricultural landowners to take the lead on implementing conservation practices that protect water quality. Those who implement and maintain approved conservation practices will be certified and in turn obtain regulatory certainty for a period of ten years. This program will help address concerns about changing regulatory requirements from multiple state and federal agencies.
The International Water Institute (IWI) will monitor 42 sites (3 basin, 12 major watershed, and 27 subwatershed) in the Red River and Upper Mississippi River Basins intensively during 2016, 2017, 2018 and 2019. There will also be 5 sites in the Red River Basin where mercury samples will be collected in 2016 and 2017 and sent to Minnesota Department of Health for analysis. The IWI will collect water samples across the range of flow conditions targeting sample collection at times of moderate to high flow.
The Six Lakes subwatershed analysis will utilize previously completed watershed modeling to conduct subwatershed analyses for six high priority lakes that are closest to meeting state water quality standards or require protection due to high public use and declining water quality trends. This project will develop a long list of cost benefit ranked water quality best management practices based on concept design.
This project will build off the success of the additional geographic information system (GIS) and water planning expertise the TSA8 added in 2016 to provide consistent mapping, water planning assistance and training to partners. This project will help soil and water conservation districts prepare for the 1W1P process before the planning starts. A unified protection methodology is essential for the 1W1P process to be successful. This project will include: unified GIS mapping and protection model for all nine counties respectively.
This project will continue to protect and improve Valley Creek, a world-class trout stream located in the Valley Branch Watershed District. Stabilizing Ravine 2E, which conveys runoff from a 150-acre watershed directly into the main stem of Valley Creek, will prevent 7 tons of sediment from depositing in the creek and silting over trout spawning sites on an annual basis. It will also reduce the annual total phosphorus load to Valley Creek and the nutrient-impaired Lake St. Croix by 51 pounds per year.
As part of the Minnesota Pollution Control Agency's (MPCA's) watershed monitoring Approach, the Washington Conservation District will collect water quality samples on three lakes in the Lower St. Croix River Watershed in 2019-20; Comfort Lake, Square Lake, and Big Marine Lake. Rural and agricultural land uses are major components of all three lakes' subwatersheds and semi-urban land use is present in the Comfort lake subwatershed.
Brown's Creek Watershed District, City of Stillwater and Oak Glen Golf Course will work together to harvest and reuse stormwater for golf course irrigation, reducing thermal loading to Brown?s Creek, a designated trout stream listed as impaired due to high thermal and total suspended solids loading, and reduce phosphorous loading to Lake St. Croix, impaired for excess nutrients. The primary goals are to reduce phosphorous loading to Brown?s Creek and the St. Croix River/Lake St Croix by 67-124 pounds per year and thermal loading to Brown?s Creek by 0.4 degrees Celsius.
The Olmsted County Soil and Water Conservation District will assist the Minnesota Pollution Control Agency (MPCA) with water quality monitoring and pollutant load calculations at four sub-watershed sites in the Zumbro River Watershed. Approximately 25 grab samples per site between ice-out and October 31 of 2019 will be collected along with field measurements and observations. Samples will be collected using procedures described in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance (SOPG).
