This project will be a complete TMDL report for the Biota and Bacteria (E. coli) impairments for the Ann River Watershed. The water bodies associated with these impairments will then be removed from the MPCA’s impaired waters list, and implementation activities to restore the water bodies will begin.
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 spatial and temporal revisions , recalibration and validation of 7 watershed HSPF models. These fully functioning calibrated validated executable models will simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, dissolved oxygen, biochemical oxygen demand, and algae at the 12-digit HUC subbasin scale (or finer).
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 Snake River Watershed Management Board (SRWMB), working in concert with other local governmental units in within the watershed, will assist the MPCA, the project consultant, and other members of the Snake River Watershed Total Maximum Daily Load (TMDL) technical team in the completion of tasks associated with this TMDL project. SRWMB, with assistance from members of the technical team (Kanabec Soil and Water Conservation District (SWCD), Pine SWCD, Aitkin SWCD, and Mille Lacs SWCD) will provide the services to complete this TMDL project.
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 extend the existing HSPF models through 2012 in the Chippewa Watershed (07020005) and Hawk-Yellow Medicine Watershed (07020004) to incorporate recent monitoring data to support current MPCA business needs and sediment source investigations.
Construct, calibrate, and validate three Hydrologic Simulation Program FORTRAN (HSPF) watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs).
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.
This project will complete spatial and temporal revisions of 6 Hydrologic Simulation Program FORTRAN (HSPF) models, the recalibration and validation of 7 watershed HSPF models, and the revision of the drainage network and point source representation of the Pomme de Terre HSPF model.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models, which simulate flow and pollutant transport, need to be refined to be consistent with the most recent external sources of land use, hydrologic response, and surface flow attributions. The primary goal of this work is to refine the hydrologic calibration in the Minnesota River basin.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models simulate sediment erosion and transport, however these models periodically need to be adjusted to be consistent with the most recent sources of information regarding sediment distribution and loading rates. The goal of this project is to refine the sediment source partitioning and simulation in the Minnesota River basin using all relevant available sources of information.
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.
The goal of this project is to refine the nutrient and algae simulation in the Minnesota River basin using all relevant available sources of information. The outcome of this work order is a revised Hydrological Simulation Program – FORTRAN (HSPF) watershed model application for the Minnesota River basin that correctly represents nutrient sources and algae.
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.
