A new study led by Northern Arizona University researchers warns that climate change could significantly reduce water flow from the headwaters of Western U.S. rivers. Analyzing 75 years of streamflow data from 115 basins across 11 Western states, the research finds that groundwater-fed streamflow (base flow) has declined since 1950 and could drop by 45% to 65% by the end of the century under current climate trends. The study attributes this decline to rising temperatures, reduced snowpack, and shifting precipitation patterns, which alter the timing and volume of water available. Researchers note that peak base flow is occurring earlier in the year, leading to lower groundwater contributions during critical late summer months when water demand is highest. The findings highlight growing concerns about the sustainability of water supplies for both human communities and ecosystems.
