Title:
Groundwater level targets and baseflow targets used to calibrate a regional groundwater flow model for the Park Falls Unit of the Chequamegon-Nicolet National Forest, Wisconsin
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This dataset consists of targets used to calibrate a regional groundwater flow model. Points include the target name; type of measurement (gage or piezometer); measured value (stream baseflow in cubic feet per day or water level elevation in feet, respectively); the modeled value at the same location; and the residual (measured minus modeled value). The groundwater flow model was created using the analytic element code GFLOW. The methodology and results are documented in an accompanying summary report available from the Wisconsin Geological and Natural History Survey. The groundwater flow model is a two-dimensional regional model and may not be accurate for site-specific applications.
Purpose:
This dataset was produced as part of a project to assess groundwater resources across the Chequamegon-Nicolet National Forest. Groundwater is an important resource for the forest, and a more comprehensive understanding of this resource can help guide land management decisions. Targets, or field measurements of water levels in wells and stream discharge, were used to calibrate a regional groundwater flow model. The difference between the measured and simulated values are useful for evaluating the model performance. The datasets produced as part of this project are divided by location into four groups, corresponding to the four main National Forest Units: Medford, Nicolet, Park Falls, and Washburn/Great Divide. This dataset is located in the Park Falls Unit.

Data_Quality_Information:
Completeness_Report:
The targets in this dataset include measured values of varying quality. The simulated values were exported from a two-dimensional, regional groundwater flow model. Areas near surface water features and areas with local subsurface variability not captured in the model may not be represented well. Model construction and evaluation is documented in the accompanying report.

Source_Contribution:
This dataset provides locations of targets used for calibrating a regional groundwater flow model for the Washburn/Great Divide Unit of the Chequamegon-Nicolet National Forest in Wisconsin. For gage targets, stream discharge measurements were adjusted to represent only baseflow (the groundwater component of flow). The methodology and results are documented in an accompanying summary report available from WGNHS.

Entity_and_Attribute_Overview:
Label: A name assigned to each target used by the U.S Geological Survey. ObsHead: Observed head - The measured water level elevation in feet for piezometer (water level) targets. ModelHead: Modeled head - The model-simulated water level elevation in feet for piezometer (water level) targets. ObsStreamF: Observed baseflow – The measured stream discharge in cubic feet per day for gage (baseflow) targets, adjusted to represent baseflow, the groundwater component of streamflow. ModelFlow: Modeled baseflow – The model-simulated stream baseflow in cubic feet per day. Type: The type of target, either piezometer (water level target) or gage (baseflow target). Residual: Equivalent to the measured target value minus the modeled value.
