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.
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.
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.
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 The Metro Model 2 is a modern and comprehensive groundwater model of the Twin Cities area, but it is currently out-of-date.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.
