The DNR is working with local communities and an interagency team to define, prioritize, and establish groundwater management areas in Minnesota. Groundwater management areas will have increased data collection and monitoring that allow the state and local communities to understand water supplies, uses, limitations, and threats to natural resources that depend on groundwater. This information will support detailed aquifer protection plans that ensure equitable and sustainable groundwater and drinking water use for the future.
Continued TMDL project to support next phases associated with completion of TMDL's for ten lakes in the Carnelian Marine Saint Croix Watershed District (CMSCWD). Ten lakes are; East Boot, Fish, Goose, Hay, Jellum’s, Long, Loon, Louise, Mud and South Twin.
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.
TMDL project in the Chisago Lakes Lake Improvement District that will develop a watershed based plan and provide strategies for water quality and aquatic ecosystem management, restoration, and protection within Sunrise River Watershed. This project will also aid in understanding the Phosphorus loading to Lake St. Croix.
The VLAWMO watershed covers approximately 25 square miles in the northeast metropolitan area in northern Ramsey County and a small portion of Anoka County, Minnesota. It encompasses the City of North Oaks and portions of the Cities of White Bear Lake, Gem Lake, Vadnais Heights, Lino Lakes, and White Bear Township. This project will gather and organize existing data, support the continuation of modeling and TMDL allocations along with an additional stakeholder meeting. It will also provide the completion of a draft and final TMDL report.
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.
The goal of this project is to refine the segmentation, extend the simulation period, and recalibrate an existing Hydrologic Simulation Program FORTRAN (HSPF) watershed model for the Rum River Watershed.
The consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
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.
As the Metropolitan Council updated the Twin Cities Metropolitan Area Master Water Supply Plan, stakeholders asked the Council to consider the sustainable limits of the region’s water sources. The Council’s most important analytical tool is a regional groundwater flow model (Metro Model 3), which can be used to quantify the long-term regional impacts caused by hundreds of independent groundwater appropriations.
The purpose of the project is to collect data to represent the ambient condition of the lakes and streams of the Rum River Watershed within Mille Lacs, Isanti and Sherburne Counties that is needed to determine if thresholds set to protect designeated uses, such as aquatic recreation and aquatic life, are being met .
This project will apply the Sunrise River watershed computer model generated under previous projects to selected scenarios of land-cover and land-management changes. The watershed model calibrated to conditions in the late 1990s will form the initial baseline against which all other model runs will be contrasted. Scenarios to be run will include changes in future land cover, agricultural practices, urban practices, and natural resource management.
State law charges the Metropolitan Council (Council) with developing and maintaining a base of technical information needed for sound water supply decisions (Minnesota Statutes 473.1565). The Council’s primary tool to provide this information is the Metro Model 2, a regional groundwater model capable of predicting the impacts of planned water demand on aquifers and connected lakes and streams. The Metro Model 2 is a modern and comprehensive groundwater model of the Twin Cities area, but it is currently out-of-date.
Regional recharge modeling with the Twin Cities daily soil water balance (SWB) model has been a fundamental part of the Metropolitan Council’s groundwater flow modeling effort and supports the Metropolitan Area Master Water Supply Plan. The SWB model is used to evaluate the impact of planned and potential land use and climate on recharge in the eleven-county metropolitan area, and supports the ongoing update of the regional groundwater flow model.
This project delineates and maps watersheds (drainage areas) of lakes, rivers, streams, and wetlands for the state of Minnesota and provides watershed maps in digital form for use in geographic information systems. These maps become the basis for clean water planning and implementation efforts.
The DNR's Regional Clean Water Specialists and Area Hydrologists work with other state agencies and local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. A statewide coordinator works with the DNR and external partners to ensure funds are spent in the most effective and efficient manner to meet the State's clean water goals.
The DNR provides technical support to watershed managers and landowners regarding drainage issues. Drainage experts are using a state of the art computer model to look at cumulative impacts of drainage and land-use practices and determine the benefits of site-specific best management practice. This work is with multiple partners and at multiple scales.
