| Ground-water recharge | ||
| Ground-water inflow from Carson Range, Pine Nut Mountains, and Eagle Valley, and recharge from precipitation on alluvial fans eolian sand, and gravel deposits | 122,000 – 40,000 | 238,000 |
| Ground-water recharge from runoff of the Carson River | 110,000 | 110,000 |
| Secondary recharge of pumped ground water | 13,000 – 6,000 | 13,000 – 6,000 |
| Total | 35,000 – 56,000 | 51,000 – 54,000 |
| Ground-water discharge | ||
| Ground-water evapotranspiration from phreatophytic and riparian vegetation and non-irrigated pasture grasses | 111,000 | |
| Ground-water discharge to streamflow of the Carson River | 115,000 | |
| Net ground-water pumping | 318,000 – 21,000 | |
| Total | 44,000 – 47,000 | |
