Potentiometric-surface altitude contours for the shallow groundwater system in the Lower Gunnison River Basin, Colorado

This dataset consists of contours showing the generalized altitude of the potentiometric surface for the shallow groundwater system in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Potentiometric-surface altitude was contoured from values in the raster dataset potalt. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Water Conservation Board.
