Water use and shortages 
The West Walker River flows through Smith Valley, and for more than a century the flows of the Walker have been diverted to irrigate farms and ranches. Diversions of the Walker River have contributed to near complete ecosystem collapse of Walker Lake. The primary crops grown in Smith Valley are alfalfa and hay.

In addition to the use of surface water that has led to the ecological collapse of Walker Lake, Smith Valley water users have withdrawn groundwater at an unsustainable rate for at least 50 years. In 2015, the Nevada Department of Water Resources issues Order 1267, limiting the use of supplemental groundwater in Smith and Mason Valleys. The order was subsequently struck down by state district court, as the order's 50% curtailment of all supplemental groundwater rights was found to abridge the priority dates of some supplemental groundwater right owners. In 2022, a study by the Nevada Department of Water Resources indicated that the groundwater table in Smith Valley has declined by more than  in the last 50 years and that more than  of groundwater have been withdrawn from the valley.  During the same time period, the Walker River through Smith Valley has significantly declined in stream efficiency, suggesting that groundwater pumping is leading to more river water leaving the channel to the groundwater table each year.
