It will provide cost share funding to organizations and associations who voluntarily construct medium sized water quality best management practices (BMPs) in Dakota County.
The Winona County Soil and Water Conservation District (SWCD) developed this project to help reduce the amount of pathogens and nutrients generated by livestock from reaching surface waters and groundwater by targeting feedlots located in areas that are highly susceptible to groundwater pollution and sinkhole formation.
This project will use the Dakota County Soil and Water Conservation District's existing Conservation Initiative Funding program to provide technical assistance and monetary incentives for targeted, medium-sized projects such as raingardens, bioinfiltration, biofiltration, bioswales, shoreline stabilizations, and other best management practices (BMPs). Project proposals will be solicited from faith based organizations, homeowner associations, school organizations, lake associations, and others that own or manage large areas of land.
The Vermillion River Watershed Joint Powers Organization, in partnership with the City of Burnsville, is planning an overall improvement in the Alimagnet Lake subwatershed that consists retrofit two existing stormwater ponds that drain to Alimagnet Lake, a nutrient impaired water, with iron-enhanced sand filter benches. It is estimated that a significant amount of phosphorus reduction will be achieved by implementing this project, bringing Alimagnet Lake closer to state water quality standards.
As part of the Dakota County Transportation Department's highway 78 road reconstruction project, the Vermillion River Watershed Joint Powers Organization is partnering with Dakota County to install a nitrate treatment practice on a tributary to the South Branch Vermillion River adjacent to the road. The South Branch Vermillion River subwatershed is the highest nitrate loading subwatershed in the Vermillion River Watershed and is a significant contributor to contaminated drinking water in the eastern portion of the watershed.
South Creek is a tributary to the Vermillion River and a DNR-designated trout stream. Currently, the creek is not meeting state water quality standards for sediment, temperature and dissolved oxygen The Vermillion River Watershed Joint Powers Organization and the City of Lakeville propose to retrofit an existing stormwater pipe with a hydrodynamic separator to reduce the sediment load reaching South Creek and the Vermillion River. One hydrodynamic separator will be installed and is estimated to reduce sediment loads to South Creek and the Vermillion River by 4 tons per year.
The Vermillion River Watershed JPO is partnering with Dakota County and the City of Lakeville to enhance stormwater management along County Road 50. A treatment train approach with an iron-enhanced sand filter at the tail end to remove dissolved phosphorus will be implemented to treat a drainage area including a portion of the upstream neighborhoods that currently receive little to no stormwater treatment. The practice is anticipated to reduce 20 pounds of phosphorus annually from reaching Lake Marion, a water resource with high recreational value targeted for protection.
South Creek, a tributary to the Vermillion River and a DNR-designated trout stream. Currently, the creek is not meeting state water quality standards for sediment, temperature and dissolved oxygen and it flows through a large stormwater basin in the City of Lakeville. The Vermillion River Watershed Joint Powers Organization, in partnership with the city, propose to create a new channel for the creek in order to separate it from the pond. The result would be significantly cooler temperatures, increased dissolved oxygen, and less sediment-laden water in South Creek.

The City of Waconia will implement its 2012-13 Storm Pond Cleaning Project and 2012 Improvement Project which includes removal and disposal of more than 2,200 cubic yards of PAH contaminated sediment from 3 stormwater ponds. The contaminated sediment will be disposed of in the Waste Management industrial landfill located in Burnsville, MN.
The purpose of this project is to project the ground water aquifer serving the City of Long Prairie through assisting low income landowners in the replacement of 12 sub-surface treatment systems that have been documented as failing to protect groundwater within the Long Prairie Drinking Water Supply Management Area. Although the primary driver is ground water protection, replacing these failing systems will also protect surface water of which Lake Charlotte is in close proximity.
The St. Cloud Waste Water Treatment Facility (SCWWTF) is currently conducting long term planning for future biosolids management. The most likely path forward includes dewatering of the digested biosolids, which will produce a supernatant stream with significant phosphorus and ammonia loads that would be returned to the liquids treatment portion of the WWTF. Returning these nutrient loads to the liquids train would result in increases to effluent concentrations, increases in power consumption, or both.
This project willl complete a final TMDL document that will be submitted to EPA for approval. Document will include Lake Osakis, Clifford Lake, Faille Lake, and Smith Lake impairments. A final technical memorandum describing the elements of the model framework and any deviations from the recommended construction methodology will be also be provided with the submission of the watershed models.
This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed.

Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
After 6 years of intensive baseline monitoring at 5 edge-of-field sites, 1 intermittent and 3 in-stream sites in 3 sub-watersheds representing the geomorphic regions of the Root River, the second phase of the project is well prepared for the implementation of BMPs. Continued monitoring will be used to measure the effectiveness of the BMPs for the next 6 years. In preparation for BMP implementation, extensive planning was completed using LiDAR terrain analysis and the Tomer Framework to prioritize practices.
This monitoring effort will focus on collecting chemistry and field data information from six sample locations on Hay Creek, Wells Creek, Bullard Creek and Gilbert Creek in Goodhue County and Miller Creek in Wabasha County within the Mississippi River-Lake Pepin Watershed (MRLP). These streams are typically cold water streams which outlet directly to the Mississippi River or Lake Pepin. This monitoring effort is to assist with the 10-year watershed-monitoring schedule that the Minnesota Pollution Control Agency has placed on major watersheds across the State.
This project will support construction of three watershed framework models built using the Hydrologic Simulation Program FORTRAN (HSPF). These executable models will simulate hydrology at the subbasin scale. An HSPF model will be built for each of these major watersheds: Crow Wing River, Redeye River, and Long Prairie River.
This project will continue HSPF watershed model construction beyond the initial framework development. The consultant will add representation of point source discharges to the model. The consultant will also compile flow data for the purposes of calibration and validation. Finally, an initial hydrologic calibration will be performed and submitted for approval.
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.
King Park, a city-owned park in Lakeville, consists of baseball fields, a park building, and a parking lot. A portion of Dodd Blvd, a driveway, and the parking lot drain to a stormwater pond at the north end of the park where water is retained, treated, and reused to irrigate two ball fields. This stormwater reuse project was constructed by the Vermillion River Watershed Joint Powers Organization (VRWJPO) and the City of Lakeville in 2010 to meet VRWJPO and city goals.
