This archive contains data supporting the analysis discussed in the project report. That data contains the groundwater flow model files, basemap coverages, crop land use rasters, and zones of contribution to the springs.

GROUNDWATE FLOW MODELS

These files are found in the base directory of the archive. There are three GFLOW models and associated support files that were used to generate the zones of contribution (ZOCs) to the springs.  
The models are: 
—DoorNorth_101wDavis_ZOCsforSprings.gfl
—KelnerArbter15_DunesLake_ZOCsforSprings.gfl
—Gardner_01_ZOCforSprings.gfl

The models were created by Cobb and Bradbury (2008). They are unaltered with the exception of the DoorNorth_101wDavis_ZOCsforSprings.gfl model. A line sink using lidar elevations representing Davis Spring and the stream from the spring was added to the original model. The only other changes are the additional of the zone of contribution for the study springs into each model. Those ZOCs are easily verified by running the model with forward particle tracking.  No other changes to model parameters or boundary conditions were made. 

BASEMAPS

These coverages are from Door County and the Wisconsin Geological and Natural History Survey. The basemaps are general, representing roads, rivers, Hines Emerald locations, and air photos. Basemaps are available from the Door County portal (http://map.co.door.wi.us/map/).

CropsZOCs

These are raster images downloaded from the USDA CropScape - National Agricultural Statistics Service (NASS) Cropland Data Layer (CDL) Program.  The data used are from 2017 and are clipped to each spring's ZOC.

SpringZOCs

These are the zones of contribution for each of the study springs as derived from the three groundwater models discussed above.  They were used to identify the land area of groundwater recharge to the springs and the land use for the spring.
