Metro Model 2 Datasets

Datasets and models are still under development and will not be considered final until the Metropolitan Area Master Water Supply Plan has been fully approved by the Metropolitan Council and the Minnesota Department of Natural Resources. On March 26, 2009, the Master Plan was provisionally approved by the Metropolitan Area Water Supply Advisory Committee. The conditional approval allows for a 6-month period in which to evaluate how the plan’s implementation affects local water appropriation permitting decision. The committee will reconvene in October 2009 to hear a report on the results of plan implementation and any recommended changes. Following this meeting, the plan is expected to be fully approved. No changes are expected to be made to the Metro Model 2. However, datasets and models will not be considered final until that time.

This website was last updated on July 6, 2009 and provides the datasets used to support the March 26, 2009 version of the Metropolitan Area Master Water Supply Plan.

Model Support Files – Zipped ArcGIS features, layer files (.lyr), and metadata (.xml)

• CalibrationTargets.zip (740 KB), ArcGIS point features of static water level, aquifer test, and baseflow calibration targets. Dataset includes model residuals.
• GeologyGrids.zip (2.412 MB), ArcGIS raster for use defining model layer surface elevations.
• GWVmaps.zip (4.595 MB), Groundwater Vistas map files for use as a spatial reference when using the model. Other ArcGIS features may also be imported to Groundwater Vistas as reference maps.
• HeadContours.zip (810 KB), ArcGIS line features of head contours for model layers 1-9 in the calibrated Groundwater Vistas model.
• HeadDEMs.zip (1.517 MB), ArcGIS rasters representing head for model layers 1-9 in the calibrated Groundwater Vistas model.
• Kvalues.zip (1.846 MB), ArcGIS polygon feature defining the hydraulic conductivity value assigned to each cell in all 9 layers of the Groundwater Vistas model.
• Kzones.zip (1.811 MB), ArcGIS polygon and raster features defining hydraulic conductivity zone boundaries for each geologic unit included in the Groundwater Vistas model. Polygon shapefiles include hydraulic conductivity zone numbers but not hydraulic conductivity values. A raster file represents average sand content (%) of Quaternary sediments, which was used to delineate hydraulic conductivity zones that unit.
• LakesRivers.zip (2.207 MB), ArcGIS line and polygon features imported to the Groundwater Vistas model as MODFLOW river boundary conditions.
• Leakage.zip (312 KB), ArcGIS raster defining the flux between model layers for each active cell in the calibrated Groundwater Vistas model.
• ModelActiveArea.zip (16 KB), ArcGIS polygon feature defining the extent of active model cells within the Groundwater Vistas model domain.
• ModelGrid.zip (1.975 MB), ArcGIS polygon feature defining the cell geometry of the Groundwater Vistas model domain.
• Recharge.zip (1.799 MB), ArcGIS raster and polygon files defining estimated recharge across the model domain, as calculated using daily soil-water balance method, and the final model-calibrated value of recharge.
• Withdrawals.zip (93 KB), ArcGIS point feature defining the location and average daily 1995-2005 rate of groundwater withdrawals in the calibrated Groundwater Vistas model.

 

Underlying Datasets – Zipped MS Word and Excel files

• StreamFlow_LateSeason_Jun07.zip (549 KB), MS Excel workbook summarizing low flow data collected at locations throughout the Twin Cities eleven-county metropolitan area. This dataset supported the development of model baseflow calibration targets.
• AquiferTests_WHPP_Dec08.xls (52 KB), MS Excel workbook summarizing aquifer test data collected through review of community wellhead protection plans submitted to the Metropolitan Council. This dataset supported the development of model transmissivity calibration targets.
• Lake_GWinteraction_Dec08.xls (20 KB), MS Excel workbook summarizing groundwater-lake interaction studies in the Twin Cities metropolitan area. This dataset supported the development of lake flux calibration targets.

Predictive Model Scenarios – Zipped Groundwater Vistas and ArcGIS files

• Reg_2030.zip (40.3 KB), zipped, Groundwater Vistas model files and ArcGIS raster files describing future aquifer conditions assuming traditional water supply sources are used to meet projected 2030 water demand.
