Historic Aquifer Water-Level Declines in the Southwest

Historic Aquifer Water-Level Declines in the Southwest: Historic water-level declines in producing aquifers of the arid and semiarid southwestern United States. Water levels have recovered in some areas in response to reduced pumping, optimization, and other management measures. 60 meters is approximately 200 feet, 30 meters is approximately 100 feet, and 15 meters is approximately 50 feet.
