Recent data show a snowy start to 2023 for the Colorado River basin, with heavy winter precipitation in the Rocky Mountains projected to boost spring spring runoff into Lake Powell to 117% of an average year’s flows.

But scientists say that while this winter’s snow may provide a temporary boost to major reservoirs, it will not provide enough water to fix the Southwest’s long-term supply-demand imbalance, as the beleaguered river continues to grapple with climate change and steady demand.
