The USGS StreamStats GIS application was used to delineate drainage basins for each of the karst features. In instances where the StreamStats derived basin for a karst feature was negligible, ArcGIS was used to assign the feature a 500-ft radius buffer zone in lieu of a drainage basin. ArcGIS Spatial Analyst extension was used to convert the drainage basins and buffer zones to a 10-meter resolution raster dataset.
