Table 13. Existing wells measured during study, Ash Meadows area, Nevada

Well name: Names listed in alphabetical order.

U.S. Geological Survey site identification number: A unique 15-digit number based on a latitude-longitude grid. The first six digits denote degrees, minutes, and seconds of latitude, the next seven digits denote degrees, minutes, and seconds of longitude, and the last two digits denote a unique sequence number within a 1-second grid of latitude and longitude.

Local site number: Alphanumeric identifier based on location of site within hydrographic areas and rectangular subdivisions of public lands.

Land-surface altitude: Datum is sea level. Altitudes are reported to nearest foot and were estimated from U.S. Geological Survey 1:24,000 topographic maps. Altitudes reported to nearest tenth of a foot obtained from leveling surveys.

Well depth: Datum is land surface. Well depths sounded by U.S. Geological Survey personnel or as reported in drilling logs provided to Nevada Division of Water Resources.

Top of open interval: Depth below land surface of uppermost well opening.

Bottom of open interval: Depth below land surface of lowermost well opening.

Type of open interval: P, perforated or slotted casing; X, open hole.

ET (evapotranspiration) unit: DGV, dense grassland vegetation; DMV, dense meadow vegetation; DWV, dense wetland vegetation; MBS moist bare soil; OWB, open-water body; SAV, submerged aquatic vegetation; SGV, sparse grassland vegetation; nd UCL, unclassified. See table 3 for more detailed description of ET units.

Contributing lithologic unit: Lithologic unit(s) present at interval yielding water to the well. Carb. rx., carbonate rock.
