Title | Riverine Lakes and Impoundments Simulated in the Twin Cities Metropolitan Area Groundwater-Flow Model
Abstract | This dataset contains polygons of riverine lakes simulated in the Twin Cities metropolitan area groundwater flow model version 3. Currently this model is underdevelopment and changes are expected to be made to this dataset as the model is finalized.
Purpose | This dataset was developed to be used to build a regional groundwater flow model for the Twin Cities Metropolitan Area

Section 2 | Data Quality
Attribute Accuracy | There are no known deficiencies
Logical Consistency | There are no known deficiencies
Completeness | This data reflects data based on model calibration completed in 2013.
Horizontal Positional Accuracy | Horizontal position accuracy is estimated to be +/- 100 meters.
Vertical Positional Accuracy | The vertical position accuracy is estimated to be +/- 5 meters. The elevation listed in the attributes 'Model_Stag' reflects data from a 10m digital elevation model.
Lineage | Datasets of land use developed for a regional recharge model were used to define the riverine lakes to include in this dataset. Land use data included data from the Metropolitan Council and the USGS 2006 National Land Cover Database (NLCD). The data for the recharge model was sampled to a 90m x 90 m grid. That resolution is preserved in this dataset, hence the jagged edges to many of the features. This was done to maintain a more robust connections between the recharge model and the groundwater flow model.

Overview | Model_Stag: The stage of the open water body. All values are in meters. Stage values were determined using a 10 m NED elevation model. The minimum value from the 10 m NED elevation model within the area of the water body was set as the stage. Kz_aw: Area weighted vertical hydraulic conductivity of all river boundary cells that intersect the polygon. Kz_mode: Mode of vertical hydraulic conductivity of all river boundary cells that intersect the polygon Bottom: Bottom elevation of feature. All values set as Model_Stag - 1m. Value are in meters. Thick: Thickness of bed sediments used to calculate conductance. For simplicity, all values set at 1m.
