Scientists finally know where the Colorado River’s missing water is going
Our take
Recent research has shed light on the puzzling water shortfall in the Colorado River, revealing that the issue stems from a lack of spring rain. For years, water managers have struggled to understand why the river delivers less water than anticipated, despite promising snowpack levels. The findings indicate that warmer and drier springs have led to increased plant consumption of snowmelt, compounded by sunny conditions that enhance growth and evaporation.
For years, water managers have been puzzled as the Colorado River kept delivering less water than expected—even when snowpack levels looked promising. New research reveals the missing piece: spring rain, or rather, the lack of it. Warmer, drier springs mean plants are soaking up more snowmelt before it can reach rivers, fueled by sunny skies that boost growth and evaporation. In fact, this shift explains nearly 70% of the shortfall, tying the mystery directly to the long-running Millennium drought.
