An active weather pattern over much of the Midwest and Southeast brought with it ample rain over many areas, with some places recording more than 5 inches for the week. Dry conditions were noted in the Northeast, West, and southern Plains where flash drought conditions were impacting vast portions of Texas, Oklahoma, Arkansas and into the lower Mississippi River valley. Monsoonal moisture continued to be spotty over much of Arizona and New Mexico, reaching into portions of west Texas as well as southern Colorado and Utah. Temperatures were near normal to slightly above over most of the U.S., with cooler-than-normal temperatures over portions of the West, Northeast, and Mid-Atlantic and above-normal temperatures over most of Texas, Oklahoma, Arkansas, and southern Missouri…
Most of the region had warmer-than-normal temperatures for the week, with most areas 1-3 degrees above normal. Heavy rains through western North Dakota, central and eastern South Dakota, northwest and central Nebraska, and northeastern Kansas helped with some dryness in the areas. The scattered nature of the rains left many dry, though, as summer thunderstorms were hit or miss in the region. Some improvements were made in Nebraska and central Kansas as well as on the plains of Colorado and Wyoming this week where the short-term wetness helped to alleviate concerns. Degradation took place over central Wyoming, southern South Dakota and western Kansas where longer-term dryness has been in place and most of these areas have missed out on earlier precipitation events. Exceptional drought was removed in southeast Colorado and extreme drought was reduced this week. Southeast Kansas is an area where abnormally dry and moderate drought expanded this week, as they are on the northern fringe of a flash drought that has been developing over the last 4-5 weeks…
Cooler-than-normal temperatures prevailed from the Pacific Northwest into much of California and western Nevada, where temperatures were 1-3 degrees below normal. Much of the rest of the region was normal to slightly above normal for the week. Above-normal rains fell in portions of Oregon and Washington as well as in Montana. Monsoonal moisture continues in New Mexico and Arizona, but it is widely scattered in nature compared to earlier in June. The rains did allow for some improvement in areas of New Mexico, where extreme and severe drought were reduced, and western Arizona, where severe drought was reduced. Severe drought was improved in southwest Colorado and much of the drought area of Montana had a full-category improvement. Moderate drought and abnormally dry conditions were adjusted in Washington to show a mix of improvements and some expansion of moderate drought. Extreme and exceptional drought was expanded over central Nevada and exceptional drought was expanded to include more of the San Joaquin Valley in California…
The region was mainly dry outside of some monsoonal moisture that made it into portions of West Texas and the panhandle. Portions of southwest Mississippi into southern Louisiana also benefited from above-normal precipitation this week. Some of the warmest temperatures in the country were observed in the region this week with many places having multiple days of triple-digit heat. Temperatures were 5-10 degrees above normal over much of the region as flash drought has developed. With the rapidly developing situation, without relief from the heat or precipitation, drought will continue to intensify rapidly. There were many changes to the drought intensity of the region this week, with only areas of west Texas and the panhandles of Texas and Oklahoma showing any improvements. Almost all of eastern Oklahoma, northern Texas, and Arkansas had a full-category degradation this week. Further degradation took place over central and southern Texas as well as portions of northern and western Louisiana. Coleman County, Texas had its driest January-to-June period on record going back to 1895. Other counties that had the driest first six months of the year were Bosque, Hamilton, Coryell, Wilson, Karnes, and Bee counties in Texas and Calcasieu Parish in Louisiana. There has been an uptick in the number of cattle sales taking place as water and feed demands are being impacted by the drought…
Over the next 5-7 days, it is anticipated that the monsoonal moisture will continue to bring rains throughout the Four Corners region. Active weather over the Midwest, Gulf Coast and Southeast will again bring widespread precipitation. Precipitation in the central Plains and northern Rocky Mountains will be minimal and dry conditions will continue to dominate the West as well as much of the southern Plains. Temperatures during this period will be well above normal over the western half of the U.S. with temperatures 6-9 degrees above normal while cooler-than-normal temperatures will be common over the eastern half with departures of 1-3 degrees below normal.
The 6-10 day outlooks show that the vast majority of the country has above-normal chances of recording temperatures that will be warmer than normal. The greatest probability of above-normal temperatures will be over the central to southern Plains. Alaska has above-normal chances of having cooler-than-normal temperatures during this time. The best chance of above-normal precipitation is over the Southwest and Southeast while much of the rest of the country will likely have below-normal precipitation, with the greatest chances in the Pacific Northwest and southern Plains.
They’re seeking opportunity, fairness, and a voice in decision making after a century of exclusion
Mid-morning in early September 2020, leaders from eight tribal nations met with Arizona state legislators, water engineers and policy experts via Zoom. One by one, each recounted their tribe’s history and efforts to secure water for their citizens. Half of the tribes in Arizona have unresolved claims to water. Of the 30 federally recognized sovereign tribal nations in the U.S. segment of Colorado River Basin, the vast majority, 22, are in Arizona.
Meeting that day was the Arizona Governor’s Water Augmentation, Innovation and Conservation Council, a committee of state legislators and water policy experts convened to plan for Arizona’s share of diminishing resources in the Colorado River Basin.
Not quite a year later, in August 2021, federal officials issued the first-ever shortage declaration on the river, resulting in substantial cuts to Arizona’s share of Colorado River water. The state has been working with some of the tribes with resolved, adjudicated water rights to help make up for low water levels.
On that September morning in 2020, two things had become clear: First, tribes like the Navajo Nation, Pascua Yaqui Tribe, and Yavapai-Apache Nation have found a couple of conditions in Arizona’s policy toward negotiating Indian water settlements unacceptable, thus their water rights remain unsettled. And second, tribal nations had been collaborative partners to surrounding communities and were, and continue to be, positioned to play an increasingly pivotal role throughout the basin as more tribal water rights are settled and basin-wide water supplies continue to decline.
Tribes have played a pivotal role in leasing water to support other water users and states as they cope with water shortage, for example. But with so many tribes who still have unsettled water rights and Colorado River flows declining, big questions remain for the 40 million people spread throughout the basin in seven U.S. States and Mexico—many of those questions center around the tribes.
Everyone in the basin can hear the clock, ominously dripping time like a leaky faucet. Drip: There is less water than ever before with the basin ensnared in a 22-year megadrought, the worst in the past 1,200 years, according to a recent study published in the journal Nature Climate Change. Drop: Without swift action to conserve water under the growing pressure of demand, the basin may be hurtling toward a water crisis. Drip: The basin’s existing water shortage management framework is set to expire in 2026 so negotiations to craft the next framework are underway; will tribal nations be included in those negotiations? Drop: How will water shortages affect the tribal nations in the Colorado River Basin and what role will those tribes play as all water users cope with shortage?
Generally, the Colorado River Basin’s tribes have some of the senior-most water rights on the river, based on federally “reserved” water rights with priority dates aligned with the dates reservations were established, some as early as 1865.
But even today, 12 of the basin’s tribes (most in Arizona) have unresolved water rights claims, and eight of those 12 have unquantified rights—meaning the amount of water they have a right to is not yet determined. Simply securing those water rights remains a time-consuming and arduous endeavor, in costly settlement negotiations amidst a scrum of other water users staking claims.
The water held by the basin tribes who have legally quantified water rights amounts to no small sum: 22 tribal nations retain 3.2 million acre-feet of water, or an estimated 22% to 26% of all annual water supplies in the basin, according to a 2021 brief from the Water and Tribes Initiative. This amount will likely increase over the years once more tribal water claims are resolved.
Even for tribes with settled or adjudicated water rights, some can’t access the full extent of that water because of lack of infrastructure or funding, or both. In total, just under half, or 1.5 million-acre-feet, of settled or adjudicated tribal rights have not yet been put to use by the tribes.
When adding together that unused water and unquantified water, and considering that tribes plan to fully develop and use their water, other water users in the basin wonder how it will look to integrate expanded tribal water use with existing water uses as water supplies continue to dwindle.
Lack of Representation
In one blinding instant, a flashbulb floods the adobe-walled room, illuminating a row of stoic men: seven state water commissioners standing behind then-Secretary of Commerce Herbert Hoover who sat at a desk. In front of them lies the 1922 Colorado River Compact, the formative agreement to carve up flows of the Colorado River. Within the Palace of the Governors in Santa Fe, N.M., these men divided the river into an upper and lower basin, apportioning the rights to consume 15 million acre-feet of water—their estimation of average annual river flow at the time—between the seven U.S. basin states: Colorado, New Mexico, Utah and Wyoming of the upper basin, and Arizona, California and Nevada of the lower basin, with the opportunity for lower basin states to develop an additional 1 million acre-feet from tributaries below Lee Ferry, Ariz.
The compact ushered in a new era of water management for the Colorado River Basin. But now, 100 years later, when facilitator of the Water and Tribes Initiative, Daryl Vigil, peers at this photograph of Hoover and the state water commissioners, he sees an “all monochromatic photo of older white gentlemen” who made no plan for apportioning any share of water to Native American tribes.
Since the beginning of U.S. tribal water law, sovereign tribal nations in the basin have been excluded from cornerstone water management decisions despite having senior title to water. Native American water rights were first officially recognized in 1908, over a decade before the Colorado River Compact was signed, with the U.S. Supreme Court’s Winters v. United States decision. The court found that when the federal government “reserved” territories known as reservations, it too had “reserved” sufficient water to fulfill the purposes of the reservations—these water rights are considered established at the date when the reservation was created, making them senior to all uses that came later. But having the right to reserved water didn’t mean that the tribes had access to actual “wet” water or the legal representation to quantify their water rights.
When the 1922 compact was signed, tribes were surviving a multitude of disastrous living conditions and forced assimilation produced by federal Indian policy, established after U.S. violent colonial expansion. Indigenous peoples weren’t recognized as U.S. citizens until 1924, tribal governance wasn’t federally recognized until 1934, and Native Americans couldn’t vote in every state until the 1960s. “We were surviving here on government rations in 1922 when the Law of the River was created,” says Vigil.
A 1928 survey entitled “The Problem of Indian Administration” found that 26 Western Native American reservations and their economic bases were crumbling under management of the U.S. Department of the Interior (DOI), asserting that colonialism largely destroyed their ability to hunt, gather and fish.
The report recommended educating tribes to effectively use their land and water rights, saying that administrators “should be given the duty of seeing that the Indians secure their rightful share of water.” This recommendation was not enough. Assigning concrete legal title to tribal water succumbed to federal delay—a defining feature of water rights disputes for all tribal nations.
Tribes gained some ground when, in 1963, tribal water policy and Colorado River policy intersected in the U.S. Supreme Court’s Arizona v. California decision. Lengthy litigation led up to the decision, with Arizona filing suit in the U.S. Supreme Court to determine how much Colorado River water it could use. To answer that question, the U.S. found it had to assess what reserved water rights were needed for some of the tribes in the lower basin. A special master for the case determined the future needs of each reservation by assessing the amount of practicably irrigable acres and reserving water to irrigate that land rather than considering the reservations’ populations. In his proposed decree, which was upheld by the Supreme Court, the special master entered a quantified water right for five reservations on the mainstem of the Colorado River, granting 905,496 acre-feet of water for 135,636 irrigable acres.
After the case established the standard of quantifying the tribal reserved water right as looking at the amount of water required to irrigate the irrigable acreage on the tribal land, the push to quantify more tribal water rights ensued. But Supreme Court rulings “grew more negative,” according to a presentation from DOI. In 1989, DOI adopted the policy to resolve Indian water disputes through settlement rather than litigation, creating the Secretary’s Indian Water Rights Office. To reach agreement, Indigenous nations must negotiate their rights within a massive tangle of other users staking claims to water within the state where their reservation is located, which can take decades. Once all parties concur, Congress must approve the agreement by passing legislation to fund any tribal water infrastructure projects.
As federal tribal water policy evolved, so too did Colorado River policy. After the 1922 compact, a series of layered agreements—including Arizona v. California and other court decisions, congressional acts, legal settlements, treaties and compacts—known collectively as the “Law of the River” have come to govern the way water is managed and divided throughout the basin.
The latest layers of the Law of the River have been implemented since 2000, in response to years of drought. In 2007, the U.S. Secretary of the Interior adopted the Interim Guidelines for Lower Basin Shortages and Coordinated Operations for Lake Powell and Lake Mead. The Interim Guidelines outline a method to balance the amount of water available between the upper and lower basins. In 2019, upper and lower basin Drought Contingency Plans (DCPs) were developed as additional frameworks to address water shortages and water-saving rules.
The upper basin continues to “equalize” the contents of Lake Powell and Lake Mead per the 2007 guidelines, and continues to pursue water augmentation activities such as cloud seeding. It is also exploring the possibility of developing a demand management program in which water saved or not used in the upper basin could be stored in Powell as a 500,000 acre-foot drought pool, though the Colorado Water Conservation Board put a “hard pause” on Colorado’s demand management investigation in March 2022. For the lower basin, the DCP, a Binational Water Scarcity Contingency Plan with Mexico, and the 2007 guidelines lay out cuts in water deliveries from the Colorado River, triggered by projections of Lake Mead storage elevations. The interim guidelines already outlined cuts but the DCP added additional delivery reductions for the lower basin states and Mexico to absorb. The greatest cuts to lower basin water use will come from Arizona and California but the entire lower basin, including Mexico, will share in scarcity.
When these guidelines and plans were crafted, all but the Lower Basin DCP received little to no tribal input. These plans will expire in 2026, and negotiations for the next phase of shortage-sharing agreements are just beginning.
Vigil, who is also water administrator for the Jicarilla Apache Nation from New Mexico, joined the Water and Tribes Initiative in 2017 to facilitate tribal discussions, protect water rights, and unify tribal interests within the Colorado River Basin. Their tribal leader forums helped spur a coalition of the tribes in the basin to call for inclusion in water framework negotiations.
When new guidelines are developed to govern river management beyond 2026, how will they affect existing tribal water rights or unresolved water claims? “Those are questions that are not yet clear to the Ute Mountain Ute Tribe and probably other tribes,” says Leland Begay, water attorney for the Ute Mountain Ute Tribe, which has adjudicated water rights in Colorado but has not yet resolved its water rights in New Mexico and Utah.
Settled Water Rights for the Colorado Ute Tribes
During the hot summers of his childhood, Lyndreth Wall of the Ute Mountain Ute Tribe would take refuge on Ute Mountain in southwestern Colorado, herding livestock at his grandparents’ sheep camp. They spoke only Ute to him, which he picked up fast, at least conversationally. In those days, the 1970s, the water on Ute Mountain was delicious. “The tribe took care of the water there,” Wall says. But his home tap water in Towaoc tasted like metal. It was “disgusting,” he says, and could make you sick. In White Mesa, their western tribal community in Utah, the water was worse—contaminated by radioactive waste.
For young Wall, his neighbors, family and livestock, the journey to procure drinkable water would be a 30- to 120-mile round trip excursion from Towaoc to Cortez or Mancos, even Durango, Colo. Wall remembers his parents packing buckets in their family pickup—the Wall’s buckets mixed with those of neighbors. This supply would last a few days before they would need more.
Today, more Ute Mountain Ute tribal members have water for drinking and irrigation thanks to the 1986 Colorado Ute Indian Water Rights Final Settlement Agreement, followed two years later by a federal settlement act, and by amendments in 2000, all of which they share with the Southern Ute Indian Tribe. The settlement places the Colorado Ute tribes among the four tribes in the upper Colorado River Basin that have completed water rights settlements, which also means that the State of Colorado is no longer negotiating any tribal settlement agreements.
For the Ute Mountain Ute Tribe, the settlement meant access to Dolores Project water, an entitlement to Animas-La Plata Project water, and rights to over 27,000 acre-feet of water from rivers that flow near or through their reservation. Most years, the Ute Mountain Ute Tribe can access their 25,100 acre-foot water storage allocation from the Dolores Project’s McPhee Reservoir in southwestern Colorado. Water from McPhee began to flow to the Ute Mountain Ute Tribe in 1994 delivering clean drinking water to the tribe for the first time in their history and supporting the development of a hotel, travel center and casino, which provide vital tribal employment and income. The tribe’s new irrigation water from the Dolores Project, up to 23,300 acre-feet per year, supported the development of the highly productive 7,700-acre Ute Mountain Ute Farm and Ranch Enterprise and Bow and Arrow corn mill.
For the Southern Ute Indian Tribe, the settlement wasn’t quite as momentous. “We have seven sources of water, seven rivers, that run to the tribe, so the tribe had been accessing those waters pre-settlement,” says Kathy Rall, head of the water resources division for the Southern Ute Indian Tribe. Before the settlement, the tribe didn’t have quantified rights to that water, Rall says. “Those rights were hammered out and solidified through the settlement,” she says. The Southern Ute Indian Tribe also received an allocation of Animas-La Plata Project water—but the infrastructure was never built for either tribe to access that water.
“Ever since [the Animas-La Plata Project] was constructed, we’ve never used a drop of it, yet we have a certain percentage, not only to us, but also our sister tribe, the Southern Ute,” says Wall, who is now a tribal councilman for the Ute Mountain Ute Tribe. The project allocated more than 60,000 acre-feet per year of municipal and industrial water to the Ute Mountain Ute Tribe and the Southern Ute Indian Tribe, but a series of obstacles has made this water inaccessible.
The settlement authorized the construction of Lake Nighthorse, just south of Durango, to store Animas-La Plata water for tribal water uses. The project was envisioned to bring water for irrigation, municipal and industrial uses to the tribes and non-tribal water users. But environmental and fiscal concerns resulted in the project being downsized.
A lawsuit halted the construction of Lake Nighthorse’s Ridges Basin Dam in 1992. Groups including the Environmental Defense Fund, Sierra Club, and the Taxpayers for the Animas River argued the dam’s cost was an undue burden for taxpayers and that its construction would threaten the Colorado pikeminnow fish population, which was federally listed as endangered at the time. Christine Arbogast, lobbyist for the Ute Mountain Ute Tribe, Southern Ute Indian Tribe, and neighboring water districts and municipalities, remembers a meeting where an environmental advocate said that with the amount of funding required to build the reservoir project, they could supply the tribe with bottled water for life. “That was the kind of mentality on the side of the environmental community,” says Arbogast.
As project proponents tried to advance Lake Nighthorse, part of the permitting requirement was to propose alternatives to the project. To address the endangered fish issues, the U.S. Fish and Wildlife Service approved an alternative that would allow for reservoir construction but with certain requirements, including a new San Juan River Basin Recovery Implementation Program. The recovery program would go on to manage the river to recover the endangered Colorado pikeminnow and the razorback sucker while allowing water development to continue.
To carry out the Animas-La Plata Project, a 2000 settlement amendment restricted the water in Lake Nighthorse to municipal and industrial use, excluding irrigation. Now referred to as “Animas-La Plata Lite” there was no longer any plan to construct the irrigation canals that would have connected Lake Nighthorse to the tribes and even neighboring water districts and municipalities that were counting on these water supplies throughout the negotiations. The tribes scrapped their plans to expand farmlands as a result. “It was heartbreaking to every single one of them, including the tribes, when we had to make the decision to shelve the irrigation component in order to get this settlement,” Arbogast says.
Some positive outcomes resulted from the settlement, including quantified and adjudicated water rights for the Southern Ute Indian Tribe, access to Dolores Project water for the Ute Mountain Ute Tribe, and funding for both tribes, Rall says. But ongoing lack of access to water stored in Lake Nighthorse and the inability to use that water, if accessed, for irrigation, was “disastrous” she says.
When the project was downsized to the “lite” version “we just kind of said, ‘OK, we’re going to get what we get,’” Rall says. “The tribe went, ‘If we don’t settle now, who knows what we’ll end up with.’”
The settlement means that the tribes’ water allocations are protected, which “does offer the tribes a measure of security in their water rights,” says Amy Ostdiek, head of the Colorado Water Conservation Board’s Interstate and Federal Section. “But there are still critical needs in terms of infrastructure and access to clean drinking water.”
As the settlement stipulates, the moment the tribes begin to use water from Lake Nighthorse, they will each inherit an annual bill of around $800,000 in operations and maintenance costs for the dam and pumping facilities that the federal government is currently footing. At the moment, there is still no infrastructure to deliver the water to the tribes, and the tribes are not prepared to take on those costs, so they haven’t used any of their water. This may change due to the $2.5 billion earmarked in the 2021 Infrastructure Investment and Jobs Act for completion of authorized Indian water rights settlements. Both Colorado Ute tribes are pursuing that funding, with full support from the State of Colorado, according to the Colorado Water Conservation Board (CWCB), but whether they will receive it remains to be seen. Information sessions on the bill between tribal nations and DOI are ongoing.
“We’re trying to find alternatives and ways that we can utilize our water in [Lake] Nighthorse. We want it and it seems like we’re having a water war,” says Wall. “What’s rightfully ours is ours by God. We need to continue to save it for the future of our tribe.”
Water or Land, Not Both
Settling and quantifying tribal water rights claims isn’t just beneficial to tribal nations. The state in which a reservation is located and other water users there benefit from the certainty of knowing how much water is allocated to the tribes so they can make plans to live within and stretch their own share or to work together to send water where it’s most needed.
But Arizona is home, at least partially, to 11 of the 12 tribal nations in the basin who still have unresolved claims to Colorado River water—resulting in uncertainty for the state and the tribes. Many tribal leaders are frustrated by the state’s unprecedented condition for tribes to secure their water rights: In exchange, tribal nations must surrender their right to freely enter fee lands into trust, an essential administrative program of the Bureau of Indian Affairs that lets tribes recover their ancestral homelands. Instead, tribes would need congressional approval to have the Interior Secretary take lands into trust.
“We just believe that the congressional process is a more equitable forum for the discussion of those lands into trust,” says Tom Buschatzke, director of the Arizona Department of Water Resources. He cites the importance of hearing from local communities that could be impacted when the tribes bring additional ancestral homelands into trust and ensuring “politically elected leaders get to make the decision.”
That stipulation is a nonstarter for many tribes, and puts them in a precarious position, weighing their right to re-acquire their ancestral homelands against securing water for their people.
“That’s something we will never agree to,” Yavapai-Apache Nation Chairman Jon Huey told the Governor’s Water Augmentation Innovation and Conservation Council during that September 2020 meeting. The Yavapai-Apache Nation plans to bring land into trust, re-acquiring its homeland to build housing for the growing tribal population.
Already, leaders from the Navajo Nation, Tonto Apache Tribe, Yavapai-Apache Nation, and Pascua Yaqui Tribe in southern Arizona have worked for decades with the state and other water districts to reach a settlement. For example, the Navajo Nation has been in recurring negotiations since 1993.
Tribes also object to a condition proposed by Arizona officials that they waive their right to object to future off-reservation groundwater pumping.
Despite hearing from leaders like Huey, the state has not changed its position. Buschatzke says these conditions are just part of the “give and take” nature of settlements. “Some things you give more of, some things you give less of,” he says. “And the whole package has to fit together for both sides at the end of the day in a way that they can live with it and in a way that they believe, hopefully, that they’re better off with the package than they are without the package.”
DOI remains dedicated to facilitating settlement discussions and is aware of the tribal concerns toward Arizona’s anti-fee-to-trust policy. “We are working from the federal perspective closely with tribal partners and with non-federal entities like the State of Arizona to bring these issues to conclusion and resolution,” says Tanya Trujillo, assistant secretary for water and science at DOI, who has been part of these tribal settlement discussions.
Working Together in Shortage
Despite some of the barriers to settlement, Buschatzke concedes that settlements provide certainty for tribes and other water users, as well as a way to work collaboratively. And now more than ever, the need to collaborate with tribes has hit harder than in the past.
The upper basin states are subject to fluctuations in hydrology, which determine the amount of Colorado River water available for their use. While the 1922 compact allocated the consumptive use of 7.5 million acre-feet of water per year to each the upper and lower basins, the upper basin regularly uses less Colorado River water than agreed to—about 4 million acre-feet per year since 1990. That’s, in part, because the upper basin hasn’t fully developed reservoirs to store extra water in times of plenty and to use its full allocation. Per the compact, upper basin states cannot deplete the river at Lee Ferry, the dividing point between the upper and lower basins, below a certain amount. That non-depletion requirement means the upper basin will likely shoulder the burden of declining flows into the future, and may have to continue to use less water.
Lower basin states rely on supplies stored in Lake Mead, the basin’s largest reservoir, which reached a historic low of just 35% of capacity in August 2021. As Mead’s water level has receded, the lower basin has begun to take cuts to the amount of water it’s drawing from the reservoir, as outlined in the 2019 Drought Contingency Plans. The first big cuts are coming from Arizona—this year it will take 18% less Colorado River water, coming almost entirely from the Central Arizona Project (CAP), slashing its CAP water use by about 30%. The CAP pipes Colorado River water to Phoenix and Tucson, and to irrigators and tribal nations in central and southern Arizona. Agricultural water users will be the first to feel these water reductions, with CAP agricultural water deliveries, mostly in Pinal County, reduced by 65%.
If Lake Mead levels continue to fall, deliveries to lower basin states will continue to be reduced, eventually affecting all lower basin states and Mexico. In February 2022 the U.S. Bureau of Reclamation projected that the reservoir level could likely drop by another 30 feet or so over the next two years, reaching new shortage tiers and triggering more cuts to lower basin states.
Tribes play a critical role in all of this: As Colorado River water supply diminishes, and as more tribes settle their water rights, those tribal water rights could comprise a larger percentage of available senior Colorado River water resources. Take the Colorado River Indian Tribes, consisting of four tribes, the Mohave, Chemehuevi, Hopi and Navajo, with a reservation along the Colorado River at the border between Arizona and California. These tribes hold rights to more than 700,000 acre-feet of mainstem Colorado River water, with more than 660,000 acre-feet of that water in Arizona. These are the most senior water rights in the lower basin, making them the most secure in times of shortage.
Starting in 2016, the Colorado River Indian Tribes entered a short-term pilot project with Reclamation, in which they were compensated for fallowing more than 1,500 acres of farmland so that water could be left in Lake Mead. Those pilot project numbers were upped in 2018. The following year, in 2019, the tribes worked with the State of Arizona on a much larger agreement, as part of the Drought Contingency Plan, committing to fallow farmland and forego water deliveries to the tune of 150,000 acre-feet over three years to help maintain levels in Lake Mead. In exchange for this contribution of water, the tribes are paid $38 million. Now, the tribes are looking to be able to lease their water—something that wasn’t authorized in the Arizona v. California opinion that established their water rights. A bill introduced to the U.S. Senate in December 2021 could allow the tribes to lease part of their water allocation to individuals, businesses, municipalities, governments and others for off-reservation uses to provide additional drought relief and protect natural habitats in Arizona.
A January 2022 agreement on the Colorado River in New Mexico does just that. The Jicarilla Apache Nation, New Mexico Interstate Stream Commission and The Nature Conservancy announced a new deal to lease up to 20,000 acre-feet of water per year from the Jicarilla Apache Nation to the stream commission to support threatened, endangered and vulnerable fish and to increase water security for New Mexico. The tribal nation subcontracts some of its other water to users outside the reservation, providing a valuable source of income.
The Colorado Ute tribes and the State of Colorado are wondering whether a similar agreement or lease deal could put their unused Animas-La Plata Project water to work, says Peter Ortego, general counsel for the Ute Mountain Ute Tribe. (Ortego also serves on the Water Education Colorado Board of Trustees.) “The tribes have been eager to see solutions to these problems and the state has been helpful in working with us to find a consumptive use for that water,” says Ortego.
Talks are preliminary and confidential, and the tribes’ settlement legislation is somewhat narrow, Ortego says, specifying that the tribes water can be leased but must be used for municipal or industrial needs within Colorado. Because Lake Nighthorse is in the southwest corner of the state, so close to the border with New Mexico, that doesn’t leave room for a lot of Colorado users to step in and lease water. However, some nearby communities are running short on water and could benefit from the supplies stored in Lake Nighthorse, if an agreement is reached. “I think we’re starting to understand now that if we can all work together to utilize that water, it will be best for the entire region,” Ortego says. “The ultimate goal is to basically keep water in Colorado to help Colorado meet its other obligations.”
More of this water sharing and leasing work could be coming. “We are very open to more discussions with tribes about what additional opportunities may exist,” says Trujillo, who has met with tribes on their ability to contribute water and receive compensation. “I think there is a lot of interest from several different angles to try to do more of that.”
Tribes Unifying in Negotiations
When he became water administrator for the Jicarilla Apache Nation, Vigil began to see how excluded tribal nations were from river management decisions.
No tribes were invited to provide input to the 2007 Interim Guidelines, which dictate reservoir operations in the event of water shortages. The guidelines were negotiated by representatives from each basin state, federal agencies, and with Mexico through the International Boundary and Water Commission—tribal water use was the responsibility of the state that the tribe resided in, so the tribes were treated as stakeholders within the states, not as sovereigns themselves. In 2012, when Reclamation completed the basin-wide Colorado River Basin Water Supply and Demand Study, tribes called attention to the fact that there was no meaningful inquiry into tribal water. It was only after pressure on Reclamation that the agency funded the Colorado River Basin Ten Tribes Partnership Tribal Water Study, which, in 2018 assessed water supplies for a coalition of 10 tribal nations in the upper and lower basins that had previously come together in 1992 to push for more tribal voices in basin water management. The study was not comprehensive of all basin tribes but gave a stronger sense of tribal water supplies. In developing the 2019 DCP, which outlined water-saving plans between the seven U.S. basin states and Mexico, Reclamation consulted with only a few lower basin tribes.
This neglect from state and federal agencies prompted the creation of the Water and Tribes Initiative in 2017. Aiming to support tribes and give them a stronger voice in water management discussions in the region, various leaders formed the initiative, including tribal representatives, policy experts, researchers, conservation groups, state and federal officials and others, co-convened by Vigil and Matt McKinney, co-chair of the University of Montana’s Natural Resources Conflict Resolution Program. “Why wouldn’t you include 30 [tribal] sovereigns who own 25% of the volume of the Colorado River?” says Vigil. “Why wouldn’t you include 30 tribal sovereigns who have been here for millennia?”
As water managers begin to plan, negotiate and draft the next river management framework that will be implemented as the Interim Guidelines and DCP expire in 2026, many tribes are actively trying to gain a seat at the negotiating table. Twenty of the basin tribes have formed an ad hoc group for all 30 of the tribes in the basin called the Colorado River Basin Tribal Coalition. As the most substantive negotiations in developing the next river management framework are likely to unfold over the next two years, the coalition is calling to work together with federal agencies and states as soon as possible. While the next set of guidelines will not affect the status of settled tribal water entitlements, many tribes are concerned that they could affect unresolved water claims, which could still take decades to settle, and their ability to plan for their future.
Rebecca Mitchell, director of the CWCB, has been meeting with the Ute Mountain Ute and Southern Ute Indian Tribes to develop a sovereign-to-sovereign framework, a process for tribes and the State of Colorado to engage on equal ground throughout water management negotiations.
“The scope of the interim guidelines will be limited to operations of the major reservoirs, so it is important to recognize that we cannot resolve all of the issues in the basin throughout that negotiation process,” Mitchell wrote in a statement via email. “Still, it will be imperative to include tribal nations in the process.”
That relationship between the Colorado Ute tribes and state has been great, says Rall with the Southern Ute Indian Tribe. “[Mitchell] is trying to lead the way for other states to do the same, hoping that other states will enter into sovereign-to-sovereign agreements with their tribes to have a seat at the table.”
For Leland Begay with the Ute Mountain Ute Tribe, early involvement in Reclamation’s next framework for managing water shortage is going to be critical for tribes to determine their future—to participate in decisions they were excluded from in years past. “In the past, there’s been a lot of shortcomings on behalf of the Bureau of Reclamation in engaging with tribes at an early stage,” says Begay. “This is an opportunity for Reclamation to meaningfully engage with tribes on how the interim guidelines impact tribes and their water rights and their land.”
It’s difficult not to view the Colorado River Compact in a global colonial context. When the compact was signed in 1922, European colonial powers were still carving up African territories, exploiting resources like copper or rubber. The U.S. empire carved up the Colorado River, splitting it among seven states, dispossessing tribes from their natural relationship with the river, with no plan to deliver them water. While the historical Law of the River can’t be removed from this context, its next era could be one where federal, state and local agencies work collaboratively with tribal nations.
Vigil has a gentle, impassioned cadence when he speaks. The river, he says, has given him a calling, a voice. Tribal nations in the basin are in a much better position today to advocate for their water interests, but it took years—a whole century really—to reach this point. It’s left him wondering: Where are we headed if we don’t start to build a collaborative framework that includes tribes?
While he talked, Vigil would occasionally chuckle or laugh in disbelief, especially about the history of tribal water rights. “I think [the laughter] is a, you know, it’s a Native thing. It’s like a way to deal with the absurdity and like the massive amount of grief that comes with having to acknowledge this and where we’re at. Like every single time.”

Colorado’s water leaders have released an updated blueprint detailing how the state will manage and conserve water supplies as climate change and population growth strain the system in unprecedented ways…
In the years since, continued warming, poor snowpack and low river flows have devastated available water supplies for farmers and ranchers. The reservoirs on the Colorado River, which starts in the mountains of Colorado and supplies more than 40 million people in the West with water, have hit critically low levels in the last year. The emergency has prompted the federal government to step in and demand the use of less Colorado River water…
The new analysis in the draft version of the new Colorado Water Plan, which was written by a team overseen by the Colorado Water Conservation Board, finds that cities, towns and industries in Colorado could be short 230,000 to 740,000 acre-feet of water annually by the year 2050 — enough water, depending on different drought and climate scenarios, to supply between 500,000 and 1.5 million homes. As the state faces warmer temperatures and less water, analysis in the draft plan finds that statewide water use in towns, cities and industries will climb between 35 percent and 77 percent by 2050…
The plan calls on leaders of Colorado’s nine river basins — known as roundtables — to identify local needs and projects that the Colorado Water Conservation Board can fund. Right now, about 1,800 such projects have been identified, a running list in various stages of readiness that comes with a hefty price tag: about $20 billion in funding to be fully completed. Some of the proposed projects include building new reservoirs and expanding old ones, watershed improvements, environmental restoration projects and infrastructure improvements.
