The Daily Sentinel –
Last winter’s big snowpack has helped ease the impacts that long-term drought has had on water storage in the Colorado River watershed, but reservoir storage levels are still low enough that provisions of a new drought contingency plan in Lower Basin states already are kicking in.
Some water officials and conservationists say the triggering of plan components reflects the fact that a single bountiful water year is far from enough for storage to recover from a mostly dry period dating back to 2000, and recently adopted drought planning measures are needed to prepare for the very real possibility that drier years will return. Those measures involve Upper Basin states including Colorado.
The reductions that the Lower Basin drought contingency plan already is requiring show that in its first year, the plan “is already working,” Chuck Cullom, Colorado River programs manager for Arizona’s Central Arizona Project, wrote in a blog on that entity’s website.
The Central Arizona Project is a water provider that will see its supplies reduced by 192,000 acre-feet next year under the plan’s provisions. That is the entire part of the state of Arizona’s Colorado River water allocation that the state instead will leave in Lake Mead under the plan, as a result of projected water levels in that reservoir at the start of next year.
