This project will provide condition monitoring and problem investigation monitoring at the following sites.
Mississippi River: Tributaries include Bassett Creek, Cannon River, Crow River, and Minnehaha Creek.
Minnesota River: Tributaries include Eagle Creek,Riley Creek, and Valley Creek tributary to the St. Croix River
On behalf of the Metropolitan Council, Environmental Financial Group Inc. generated a matrix of water conservation programs with detailed information about the costs and benefits of the programs. Tools were also developed to allow users to calculate potential water savings, estimate program implementation costs, and test the effects of various water conservation programs and rate structures.
This project will finalize HSPF watershed model construction by incorporating internal phosphorus loading in modeled lakes, run a suite of implementation scenarios and generate a GenScn project containing model output. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will deliver all modeling files for baseline and implementation scenarios and provide a GenScn project containing model output.
This project will complete a comprehensive study, following a rational, step-wise process of data analysis, response modeling and comparison to the water quality standards, followed by impairment diagnosis, modeling of improvement and protection options, and development of a WRAP Report and Implementation Plan for Sunfish lake, Thompson lake, Pickerel lake, and Rogers lake.
This project will complete a pollutant source identification and subwatershed information report and support the development of a Draft Restoration and Protection Plan (RAPP). It will also support the devlopment of a Implementation Plan that will identify target areas for BMP implementation for bacteria reductions.
This project will provide the MPCA, CCWD, and all other stakeholders the information and tools necessary to improve the water quality within Coon Creek Watershed District. The improvements will take place using targeted activities throughout the watershed to reduce the primary biological and chemical stressors. In turn, the reduction of these stressors will help to reduce overall loadings of sediment, turbidity, total phosphorus, and E. coli bacteria.
The goal of this project is to develop a phosphorus TMDL for the six impaired lakes in the southwest portion of the Rice Creek Watershed District; Island Lake, Little Lake Johanna, Long Lake, East Moore Lake, Pike Lake and Lake Valentine.
On behalf of the Metropolitan Council, Barr Engineering Company developed maps and supporting information to characterize the relationship between surface waters and groundwater, identifying surface waters most likely to be impacted by groundwater withdrawals in the region. This project also provided guidance on effective resource monitoring strategies and costs for each type of surface water feature.
The goal of this project is to construct, calibrate, and validate five Hydrologic Simulation Program FORTRAN (HSPF) watershed models. The outcome will be HSPF models that can readily be used to provide information to support conventional parameter TMDLs. These models will generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will finalize HSPF watershed model construction and complete the calibration/validation process for the following three watersheds: North Fork Crow River, South Fork Crow River, and Sauk River.
On behalf of the Metropolitan Council, the Minnesota Geological Survey collected information and conducted an assessment of the hydraulic properties and chemistry of selected aquifers in the metro area. This project greatly improves the accessibility of existing data, which were previously available only in scattered paper reports. A robust database of groundwater age, aquifer hydraulic conductivity and groundwater chemistry data was developed to make the information easily accessible to water resource managers.
On behalf of the Metropolitan Council, the Minnesota Geological Survey evaluated the vulnerability of glacial aquifers in the Twin Cities metropolitan area. The project improved upon previous vulnerability assessments by incorporating a substantial amount of new aquifer property information and blending methods previously used by the Minnesota Departments of Health and Natural Resources. The result is a consistent vulnerability assessment across the metropolitan area based on the most up-to-date information available.
This project supports monitoring and assessment activities by MPCA EAO staff and includes lab analysis, equipment, and fieldwork expenses associated with monitoring and assessment activities within the described priority watersheds.
Lake Monitoring: Lakes are monitored for nutrients, clarity and other information to provide the data needed to assess the aquatic recreation use support.
Arsenic occurs naturally in soil and minerals and is commonly found in groundwater throughout much of Minnesota. The occurrence and distribution of arsenic in groundwater is difficult to predict. Research is steadily increasing our understanding of the mechanisms and geologic conditions that determine arsenic occurrence in groundwater. The arsenic concentration in a new well, measured at the time of construction, is sometimes higher or lower, compared to subsequent sampling results.
This project will collect additional water quality and flow data on tributaries on the South Fork Crow River and Buffalo Creek. Further assessment of these reaches will provide a better understanding of what impacts these tributaries have on the impaired South Fork Crow River and Buffalo Creek.
This project will develop a watershed restoration plan that provides quantitative pollutant load reduction estimates and a set of pollutant reduction and watershed management strategies to achieve water quality standards for all impairments within the watershed. It will also an important framework for civic and citizen engagement and communication, which will contribute to long-term public participation in surface water protection and restoration activities throughout the watershed.
This project will support the monitoring of reaches where there are data gaps, incorporate new data and relevant data, continue identification of pollutant sources, complete load duration curves, coordinate and encourage participation in stakeholder meetings. The information gathered during Phase IIB will be utilized towards the development of a Draft Restoration (TMDL) and Protection Plan (Plan).
Upper Mississippi, North Fork Crow River Major Watershed TMDL Project led by CROW with assistance from local partners North Fork Crow River Watershed District (WD); Middle Fork Crow River WD; Wright Soil and Water Conservation District (SWCD).
