Colorado River Reservoirs Could Bottom Out By Mid-century

Colorado River Reservoirs Could Bottom Out

From article:

All reservoirs along the Colorado River might dry up by mid-century as the West warms, a new study finds. The probability of such a severe shortage by then runs as high as one-in-two, unless current water-management practices change, the researchers report.

The study's coauthors looked at the effects of a range of reductions in Colorado River stream flow on future reservoir levels and at the implications of different management strategies.

Even under the harshest drying caused by climate change, the large storage capacity of reservoirs on the Colorado might help sustain water supply for a few decades. However, new water management approaches are critical to minimize the chances of fully depleting reservoir storage by mid-century.

"This study, along with others that predict future flow reductions in the Colorado River Basin, suggests that water managers should begin to re-think current water management practices during the ne…
