Purpose: This dataset was completed in support of the Death Valley Ground-Water Basin regional flow model funded by the U.S. Department of Energy in conjunction with the U. S. Geological Survey and U.S. National Park Service. The proposed model is intended to address issues concerning the availability of water in Death Valley National Park and surrounding counties of Nevada and California and the migration of contaminants off of the Nevada Test Site and Yucca Mountain high-level waste repository.
