Water-Resources Investigations Report 01-4239

Ground-Water Discharge Determined from Measurements of Evapotranspiration, Other Available Hydrologic Components, and Shallow Water-Level Changes, Oasis Valley, Nye County, Nevada

Table 9. Summary of annual changes in spring discharge at spring and channel measurement sites, Oasis Valley discharge area, Nevada, 1997-99

[Site locations are given in table 8. Discharge measurements affected by local precipitation or short-term flooding are not included in annual fluctuation. Discharge reported to the nearest gallon per minute except where noted. Dash is non-applicable entry. Abbreviation: gal/min, gallons per minute]

Method of spring discharge measurement: C, current meter; E, estimated; F, Parshall flume; V, volumetric; Z, culvert computation.
