Model-simulated baseflow in the Great Divide District of the Washburn/Great Divide Unit of the Chequamegon-Nicolet National Forest, Wisconsin

- Abstract:
-
This dataset consists of simulated baseflow and groundwater discharge for each stream segment in a steady-state groundwater flow model. The lines show where streams are represented in the groundwater flow model. Each line segment has attributes for the simulated baseflow and discharge. Baseflow is the groundwater component of streamflow, in cubic feet per second (cfs); discharge is the amount of groundwater flowing into a stream along a given segment, in cfs. Negative values of discharge indicate flux from the stream into the aquifer.
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 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.
This dataset includes the simulated baseflow and groundwater discharge for each stream segment in a groundwater flow model developed for this project. These model results can be used to identify magnitude of baseflow as well as identify streams that are gaining or losing groundwater.
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 Great Divide District of the Washburn/Great Divide Unit.

- Data_Quality_Information:
-
- Completeness_Report:
-
The stream baseflow and groundwater discharge in this dataset were exported from a two-dimensional, regional groundwater flow model. Areas with local subsurface variability not captured in the model may not be represented well. The performance of the model compared to head and baseflow measurements is included in the accompanying report.

Baseflow (attribute ‘BaseflowCFS’) is defined as the groundwater component of streamflow in cubic feet per second.
Groundwater discharge (attribute ‘DischargeCFS’) is defined as the groundwater flux into a stream segment in cubic feet per second. Negative values indicate groundwater is flowing from the stream into the aquifer (losing stream).
