Abstract

Hydrologic data were collected during 1994?96 as part of the U.S. Geological Survey's long-term Volcanic Hazards Monitoring Program of the Long Valley Caldera, Mono County, California, and the Long Valley Hydrologic Advisory Committee monitoring program. Hydrologic data collected include continuous record of ground-water levels in 4 wells; instantaneous measurements of ground-water levels in 53 wells; continuous record of discharge at 2 surface-water sites and 4 springs; continuous record of stage at 1 thermal pool; instantaneous discharge measurements at 3 surface-water sites; ground-water temperature profiles of 5 thermal wells and 1 nonthermal well; continuous record of water temperature in 3 springs; vent gas temperature at 1 fumarole; and chemical and isotopic analyses of water samples collected at 5 wells, 7 springs, and 5 surface-water sites. Precipitation amounts at 3 sites, and water equivalence of snowpack at 3 sites also are included. The data are presented in graphs or tables.
