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to the use of surface water that has led to the ecological collapse of Walker Lake, Smith Valley water users have withdrawn groundwater at an unsustainable rate for at least 50 years.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Smith Valley has declined by more than 100 feet (30 m) in the last 50 years and that more than of groundwater have been withdrawn from the valley.
