Upper Colorado River Leaders Wade Into Arizona Dispute
States in the Upper Colorado River Basin are telling downstream neighbor Arizona to get its act together.
Commissioners for the Upper Colorado River sent a letter late last week to Arizona Department of Water Resources Director Tom Buschatzke. In the letter, they specifically criticized a water management strategy of the Central Arizona Water Conservation District (CAWCD).
Here’s what the upper basin doesn’t like: the CAWCD aims to keep Lake Mead at a so-called “sweet spot.” If the level of the lake stays in that range, then under current agreements, more water comes down from Lake Powell.
The Commissioners’ letter expressed deep concern that CAWCD “intends to disregard the basin’s dire situation at the expense of Lake Powell and all other basin states.” Don Ostler, executive director of the Upper Colorado River Commission, said bluntly in an interview. “That kind of manipulation is unacceptable to the Upper Basin.”
The letter echoed an argument long made by Buschatzke.
“It raises important questions about actions taken by Central Arizona Water Conservation District that threaten to blow up the collaborative effort that we have been enjoying on the Colorado River for the last 20 years,” he said.
A statement from the CAWCD, in part, said, “We are surprised and disappointed to have received a letter from the Upper Colorado River Commission questioning CAWCD’s intentions in leaving water in Lake Mead. We have been reaching out to our partners in the Upper Basin, hoping to clarify apparent misunderstandings, and to facilitate in-person, collaborative discussions aimed at finding solutions that will benefit the communities and environment served by this mighty river.”
CAWCD also reminded people of the water the agency has conserved on behalf of Lake Mead, “at a significant cost to CAP water users in terms of water and water rates.” CAWCD runs the Central Arizona Project canal system, which delivers water to the Phoenix and Tuscon areas.
The Upper Colorado River Commissioners also urged Arizona to get its internal house in order so all seven states and Mexico can plan for long-term drought.
“The seven Colorado River Basin states and Mexico are connected at the hip in this river,” Ostler said. “And what is going on with regards to one state, its failure to make progress, is having an effect on all seven states.”
Buschatzke and Gov. Doug Ducey are trying to get big-ticket water legislation through the state Capitol this year. But time is running out on the legislative session.
