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 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 primary focus of this project is the collection of lake core samples to aid in the completion of lake TMDLs for Dean, Malardi & Fountain lakes. This work will enable completing tasks included in the North Fork Crow River Watershed Restoration & Protection Project (WRPP). Additional data collection is needed to update lake response models. This new data will provide a cohesive and comprehensive data collection for Dean, Malardi and Fountain lakes.
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.
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.
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.
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.
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.
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.
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).
