Table 4. Summary of model results for 14 perennial watersheds in Carson Valley, water years 1990–2002, and comparison with estimates from Maurer and Berger (2007).
[Values in inches are volumes in acre-feet, divided by watershed area, in acres, multiplied by 12. Watershed No. ending in “u” is ungaged; watershed No. ending in “g’ is gaged watershed. Locations of watersheds are shown in figure 3. Measured or reconstructed mean annual runoff: From Maurer and others (2004, p. 14); measured for gaged watersheds; reconstructed for ungaged watersheds. Relative difference in runoff: Computed from values in acre-feet as (simulated−estimated/estimated)*100. Estimated mean annual precipitation: From Maurer and Berger (2007, p. 29). Estimated mean annual ET: Multiply reported ET rate, in feet, by watershed area to obtain ET volume in acre-feet. Estimated mean annual ground-water inflow: From Maurer and Berger (2007, p. 32). Ground-water inflow: Defined as ground-water inflow to basin-fill aquifers of Carson Valley. Abbreviations: acre-ft, acre-feet; ET, evapotranspiration]

1 About 600 acre-ft from Stutler Canyon is assumed to supply streamflow to Sheridan Creek, and is not available as ground-water inflow to basin-fill aquifers of Carson Valley. Remaining 1,000 acre-ft assumed to supply ground-water inflow to basin-fill aquifers of Carson Valley.
2 Estimates from Maurer and Berger (2007) are for the combined watersheds of Stutler Canyon and Sheridan Creeks.
3 Values of relative difference for subtotal and total are actually average values, rather than subtotals.
4 Includes 1,000 acre-ft from Stutler Canyon.
