How Colorado River Basin tribes are managing water amid historic drought

Excerpt from this story from Grist:

Amid historic drought in the Colorado River Basin, the Gila River Indian Community is taking a drastic step to protect their own water resources. In a statement last week, Governor Stephen Roe Lewis announced the tribe—located just south of Phoenix—would stop voluntarily contributing water to an important state reservoir. “We cannot continue to put the interests of all others above our own when no other parties seem committed to the common goal of a cooperative basin-wide agreement,” the statement reads.

Since 2021, Lake Mead, a crucial water supply for the region, has been boosted by voluntary water contributions from the Gila River Indian Community and the Colorado River Indian Tribes. The Colorado River is a crucial source of water in the West, supplying water to 40 million people across seven states and Mexico. For years, tribes and communities in those states have received river water based on a complex allocation system, but last week, the federal government announced historic water cuts that will force Arizona, the most impacted state, to reduce water withdrawals from the Lake Mead reservoir by 21 percent next year. Lake Mead’s levels are currently at a historic low of about 27 percent capacity.

By contributing their water to Lake Mead at affordable rates, the Gila River Indian Community was essentially subsidizing Arizona’s water supply while sacrificing an opportunity to sell that water at higher rates or put it to use on the reservation for agriculture or other industry. Now, facing cuts and other communities not willing to make sacrifices for the collective good, Gila River is putting its foot down. According to the statement, the lack of progress toward a sustainable water management plan left the tribe with no choice but to store the water independently rather than supporting the state water supply. “We are aware that this approach will have a very significant impact on the ability of the State of Arizona to make any meaningful commitment to water reductions in the basin state discussions,” Lewis said in the statement.

Meanwhile, the Colorado River Indian Tribes, which has also been contributing some of its water to help keep Lake Mead’s levels up, has opted to continue storing water in the reservoir. In a press release, chairwoman Amelia Flores reiterated her tribe’s commitment to an ongoing fallow and farming plan for their water allotments in response to the cuts. In other words, Colorado River Indian Tribes is sticking to a plan that forfeits the opportunity to maximize their agricultural and water revenues. “We recognize that the decades-long drought has reduced the water availability for all of us in the Basin,” Flores said. “We continue to conserve water and develop ways to use less water as we adjust to higher temperatures, more wind and less precipitation.”

These two decisions illustrate the difficult choices facing the thirty federally recognized tribes in the Colorado River Basin. Because tribes are sovereign governments, their water rights are determined with the federal government, rather than via the state, like cities and towns. Water rights allow tribes to maintain agricultural self-sufficiency, restore and steward the land, and support their communities. But to actually use their water, tribes face a unique set of challenges including inadequate infrastructure that limits some from accessing their water allocations. And for tribes still fighting to have their rights recognized, the ongoing shortage may make their battle even harder. As the region prepares for the cuts, tribes are working to ensure they have a voice during ongoing water management negotiations.
