The plan charts a course for the basin’s next 10 years that could lead to significant water cuts in the Lower Basin and opens up the door for more frequent negotiations…

“The basin is experiencing increased aridity due to climate variability, and long-term drought and low-runoff conditions are expected in the future,” wrote the Bureau of Reclamation in the summary. “These conditions will exacerbate the now widely recognized imbalance between water supply and demand in the basin. Robust and flexible guidelines are needed to manage the Colorado River system and its resources under a broad range of potential future hydrologic conditions.”

[…]

The two reservoirs are currently governed by guidelines established in 2007 that are set to expire this year, and many agree the plan has failed to protect the Colorado River system…The final proposal does not provide specifics for how water will be distributed across the basin, with the Bureau of Reclamation describing it as a “framework” that identifies key triggers and ranges for developing future operating guidelines at Lake Powell and Lake Mead. It sets up a plan to negotiate 2-year operating plans for the reservoirs through 2036…The final statement provides a range of alternatives, including the Bureau of Reclamation’s “preferred” option. Each alternative sets guidelines for how it will reduce or increase annual consumptive water use allocations from Lake Mead to the Lower Basin states; store and deliver water saved through conservation efforts; manage and deliver surplus water; manage activities and make cuts above Lake Powell; and more.
