If water use in the Middle Rio Grande Basin continues at its current pace, hydrological resources in the region will become steadily scarcer, concludes a newly completed five-year study by U.S. and Mexican researchers. The $4.9 million study, funded by the U.S. Department of Agriculture, gauges the sustainability of surface water and groundwater use along the Rio Grande from New Mexico’s Elephant Butte Reservoir south to the junction of Mexico’s Rio Conchos and the Rio Grande.
