Feds Seek Ideas on How to Manage a Drier Colorado River

For many decades, the Colorado River was managed with the attitude that its water levels would remain roughly stable over time, punctuated by alternating wet and dry periods.

But in the face of possibly the river’s driest period in 1,200 years, a new approach is now needed to managing the river’s reservoirs — one that can account for “deep uncertainty” about future climate and runoff conditions, says the U.S. Bureau of Reclamation.
