Table 16. Estimates of annual ground-water inflow from the California portion of Carson Valley.

Inflow source and method Ground-water inflow estimates, in acre-feet per year
Average Low range High range
Ephemeral streamflow1 4,000 2,000 6,000
Precipitation on alluvial fans2 250 200 300
Subsurface inflow from perennial stream drainages3 1,300 1,300 1,300
Total (rounded) 6,000 4,000 8,000

1 Determined from application of unit-area runoff of 0.57 ft/yr (Maurer and others, 2004, p. 17) to 7,100 acres.

2 Determined from application of recharge rates ranging from 0.03 to 0.05 ft/yr (table 7) to precipitation of 6,200 acre-ft/yr, estimated from linear relations distribution (table 5).

3 From table 11, includes subsurface flow from Stutler Canyon, Sheridan, Jobs Canyon, Luther, and Fredericksburg Canyon Creeks. Low and high range not varied.
