Opinion: Native American rights to Colorado River water

… [M]ore than a century ago, states recognized that Native Americans had rights to Colorado River water and, even earlier in 1908, the U.S. Supreme Court said in Winters v. U.S., that when we dedicated land to reservations it included enough water to make them habitable. … All that history is becoming more important because we face a deadline. Political procrastination over decades has pushed nearly every aspect of Colorado River allocation into a series of 2026 federal deadlines. … If the states and other stakeholders, like the Indian Tribes, cannot agree, then the Trump Administration will likely decide for them. … And, remember, the Indian Tribes are still getting only about a third of their water.
–Written by Ken Ransford, member of the Colorado Basin Roundtable.

‘Major milestone’: Rare animal reintroduced to California national park

… Yellow-legged frogs were once one of the most abundant animals in the alpine habitats of the Sierra Nevada. But for the past decade, the Oakland Zoo has been raising individuals from the now-endangered species and releasing them to the wild as a way to boost their numbers in the aftermath of a deadly disease that has decimated 90% of their population. Known as chytridiomycosis, or the chytrid fungus, the disease leads to “devastating effects” and has contributed to the greatest loss of biodiversity ever caused by a pathogen. … After getting swabbed for the disease one last time, they were transported to their final destination: Laurel Lake at Sequoia and Kings National Park.

Top Interior officials reassure tribes Trump administration supports their water rights

This week, the nonprofit Native American Rights Fund hosted its biennial tribal water symposium in partnership with the Western States Water Council. It’s been a tradition since 1991, but this year’s daylong gathering was virtual. The online forum brought together tribal, state and federal stakeholders to focus on Indian water settlements – past and present – and the negotiations needed for them to be ratified by lawmakers on Capitol Hill. Top-ranking Interior Department officials took time to reassure tribes that the Trump administration is behind them – despite recent staffing cuts and Congress clawing back federal dollars.

Copper mines close in on Western Apache sacred site, and the forest protected to mitigate the damage

On the banks of the San Pedro River lies one of the American Southwest’s few remaining old-growth mesquite bosques—a streamside forest in more than 3,000 acres of riparian ecosystem that is one of Arizona’s last intact landscapes. Known as the 7B Ranch, the mesquite forest is vital to the area’s biodiversity. … [J]ust eight miles up the road is another proposed mine, this one pursued by Faraday Copper, for which the Bureau of Land Management has approved exploratory drilling. Now, the San Carlos Apache Tribe and a coalition of environmental groups appealed to the BLM’s Arizona state director to review the agency’s approval of Faraday’s Copper Creek project, citing its impacts to 7B Ranch as a property mitigating the impacts of a mine elsewhere, and for the “serious risks to wildlife, water resources, landscape connectivity, human health, and cultural resources” it poses to the tribe, land and other local communities.

Yurok Tribe gains federal authority to set water quality standards on its reservation

The Environmental Protection Agency has approved the Yurok Tribe Environmental Department’s application for Treatment as a State (TAS), giving the tribe authority to set and enforce water quality standards on the Yurok Reservation in northern California. The designation, based on a 1987 amendment to the Clean Water Act, allows the department to administer federal environmental laws including the Clean Air Act, Clean Water Act and Safe Drinking Water Act within reservation boundaries. The approval applies to 44 miles of the Klamath River and its tributaries, according to a Yurok news release. Under TAS, the tribe may determine beneficial water uses based on local cultural, environmental and community considerations.

EPA grants Yurok Tribe authority to develop water quality standards

The EPA has approved the Yurok Tribe’s request for authority under the Clean Water Act to develop water quality standards for rivers and streams on its lands. “This action recognizes the Yurok Tribe’s capability to protect water resources that are vital to cultural practices, public health, and local ecosystems,” the agency said in a statement. With this approval, the Tribe can establish water quality standards for its Reservation, which will be subject to EPA review and approval before taking effect. These standards will help guide decisions on water protection and management. “The Yurok Tribe will now be able to develop standards that reflect both scientific criteria and the Tribe’s priorities for protecting fish habitat and ceremonial uses,” EPA officials said.

Spreading stories of water one exhibit at a time

The state of Arizona is home to 22 tribal nations — and all of them have a deep connection to water. However, many tribes are being left out of conversations surrounding the topic. Liliana Caughman, an assistant professor in the American Indian Studies program at Arizona State University, is working to change that. Through her lab, the Relate Lab, eight Indigenous scholars are working alongside the Arizona Water Innovation Initiative at ASU and their WaterSimmersive project to create water-related exhibits in rural communities throughout Arizona. … The Indigenous Water Stories Research Cohort is currently working with tribes like the White Mountain Apache Tribe, Colorado River Indian Tribes and Navajo Nation to relay the stories and history of water that come from each.

Tribal water settlement aims to repair generations of exclusion

… Because the Hopi—along with the nearby Navajo and San Juan Southern Paiute—live in remote areas far from major population centers, residents rely on practical solutions to survive with limited access to water. … Now, after years of negotiations, the tribes are seeing their push for long-term solutions gain renewed momentum in Congress. The Northeastern Arizona Indian Water Rights Settlement Act, reintroduced this year with bipartisan support, would resolve decades of legal disputes and devote $5 billion to delivering Colorado River water to the region through a new pipeline, pumping stations and storage systems. … The state also stands to benefit. If passed, the settlement would give tribes the authority to release water to other users—flexibility that could help ease shortages during the ongoing drought.

According to federal data, compared with white households, Native American households are 19 times more likely to lack indoor plumbing. That figure jumps significantly for Navajo residents, who are 67 times more likely than other Americans to live without access to running water. Citing this data, U.S. Sen. Martin Heinrich (D-N.M.) on Tuesday announced he and colleagues from Colorado, Democratic U.S. Senators Michael Bennet and John Hickenlooper, had introduced the Tribal Access to Clean Water Act. … The bill’s components include authorizing the United States Department of Agriculture to make grants and loans for technical and financial assistance, as well as for construction.

Tuesday Top of the Scroll: To fight cancer-causing “Erin Brockovich” toxin, California may give water districts legal cover

Lawmakers are poised to give California’s water districts legal cover from lawsuits as they work to meet strict new state standards for a cancer-causing toxic chemical.  It’s called hexavalent chromium, more commonly known as “chromium-6.” Drinking water with trace amounts of the chemical over long periods has been linked to cancer.  Last year, state water regulators approved a nation-leading drinking water standard for the chemical, which is found naturally in some California groundwater. In other areas, chromium-6 leached into the water from industrial sites.  The regulations are intended to protect more than 5 million Californians from the toxin, including in the Central Valley, Inland Empire and along the coast. Water districts say they plan to comply, but they complain the new rules are going to cost tens of millions of dollars, will jack up their customers’ water bills and could take years to complete.

Indigenous youths finish historic journey down Klamath River with help of Aspen-based nonprofit after dams removed

In a thick forest along the remote northern California coast earlier this month, a group of mostly young Indigenous kayakers pushed off into the clear-emerald waters of the recently undammed Klamath River.  The 13- to 20-year-olds from more than six tribes in the Klamath Basin, along with several instructors, had been paddling for a month, covering over 300 miles.  In just a few hours, they would reach the Pacific Ocean, making the group among the first in over a century to descend the river from its headwaters in southern Oregon to its mouth in northern California. The expedition began in early June after the largest dam-removal project in history was completed last fall to restore salmon populations, improve water quality and support tribe-managed lands.

Colorado senators reintroduce bill to improve water access in tribal communities

Colorado Sens. Michael Bennet and John Hickenlooper have reintroduced a bill to expand access to clean water in tribal communities. The Tribal Access to Clean Water Act aims to increase funding that would critically expand water infrastructure projects through the Indian Health Service, the U.S. Department of Agriculture and the Bureau of Reclamation. … The 2025 version would authorize the USDA to provide grants and loans for water infrastructure in tribal communities, increasing funding for its Rural Development programs by $100 million annually for five years, with $30 million specifically dedicated to technical assistance. It would also boost funding to the Indian Health Service for facility construction, technical assistance and operations, as well as authorize $90 million annually to the Bureau of Reclamation’s existing technical assistance program.

First Descent by tribal youth reaches conclusion at Pacific Ocean

The journey is over. The 310-mile First Descent paddle from the headwaters of the Wood River to Requa, where the Klamath Rivers pours into the Pacific Ocean, ended Friday when a group of teenaged kayakers from tribes living along the the river and its tributaries arrived at a spit at the river’s end. A gathering of relatives, friends and other watched as the kayakers broke through the fog and into view. … Along with congratulating the young paddlers and giving them words of encouragement, a recurring theme was celebrating the removal of four Klamath River dams and the return of salmon. Fittingly, the ceremonies, which moved from the spit to the road in Requa, were adjacent to what was intended to be a fish processing plant but is not operating because of the lack of salmon. Speakers also noted that weeks after the removal of the dams, salmon were seen beyond the John C. Boyle Dam near Keno.

Upper Basin tribes gain permanent foothold in Colorado River talks

Six tribes in the Upper Colorado River Basin, including two in Colorado, have gained long-awaited access to discussions about the basin’s water issues — talks that were formerly limited to states and the federal government. Under an agreement finalized this month, the tribes will meet every two months to discuss Colorado River issues with an interstate water policy commission, the Upper Colorado River Commission, or UCRC. It’s the first time in the commission’s 76-year history that tribes have been formally included, and the timing is key as negotiations about the river’s future intensify. … Most immediately, the commission wants a key number: How much water goes unused by tribes and flows down to the Lower Basin?

Addressing the Colorado River crisis

Sustaining the American Southwest is the Colorado River. But demand, damming, diversion, and drought are draining this vital water resource at alarming rates. The future of water in the region – particularly from the Colorado River – was top of mind at the 10th Annual Eccles Family Rural West Conference, an event organized by the Bill Lane Center for the American West that brings together policymakers, practitioners, and scholars to discuss solutions to urgent problems facing rural Western regions.

Blog: Senate hearing Thursday on tribal access to clean water: it takes more than just a pile of money

The U.S. Senate Indian Affairs Committee is holding an important hearing Thursday on S. 2385, a bill to refine the tools needed to help Tribal communities gain access to something that most non-Indian communities in the western United States have long taken for granted: federally subsidized systems to deliver safe, clean drinking water to our homes. … This is the sort of bill (there’s a companion on the House side) that makes a huge amount of sense, but could easily get sidetracked in the chaos of Congress. The ideal path is for the crucial vetting to happen in a process such as Thursday’s hearing, and then to attach it to one of those omnibus things that Congress uses these days to get non-controversial stuff done. Clean water for Native communities should pretty clearly be non-controversial.

WESTERN WATER IN-DEPTH: Tribes hold key state-appointed posts for first time as their water rises in value

A CAP canal in North PhoenixThe climate-driven shrinking of the Colorado River is expanding the influence of Native American tribes over how the river’s flows are divided among cities, farms and reservations across the Southwest.

The tribes are seeing the value of their largely unused river water entitlements rise as the Colorado dwindles, and they are gaining seats they’ve never had at the water bargaining table as government agencies try to redress a legacy of exclusion.

WESTERN WATER NOTEBOOK: Upper Basin States Seek Added Leverage to Protect Their River Shares Amid Difficult Talks with California and the Lower Basin

The White River winds and meanders through a valley.The states of the Lower Colorado River Basin have traditionally played an oversized role in tapping the lifeline that supplies 40 million people in the West. California, Nevada and Arizona were quicker to build major canals and dams and negotiated a landmark deal that requires the Upper Basin to send predictable flows through the Grand Canyon, even during dry years.

But with the federal government threatening unprecedented water cuts amid decades of drought and declining reservoirs, the Upper Basin states of Wyoming, Utah, Colorado and New Mexico are muscling up to protect their shares of an overallocated river whose average flows in the Upper Basin have already dropped 20 percent over the last century.

They have formed new agencies to better monitor their interests, moved influential Colorado River veterans into top negotiating posts and improved their relationships with Native American tribes that also hold substantial claims to the river.

As Colorado River Flows Drop and Tensions Rise, Water Interests Struggle to Find Solutions That All Can Accept
WESTERN WATER IN-DEPTH: Chorus of experts warn climate change has rendered old assumptions outdated about what the Colorado River can provide, leaving painful water cuts as the only way forward

Photo shows Hoover Dam’s intake towers protruding from the surface of Lake Mead near Las Vegas, where water levels have dropped to record lows amid a 22-year drought. When the Colorado River Compact was signed 100 years ago, the negotiators for seven Western states bet that the river they were dividing would have ample water to meet everyone’s needs – even those not seated around the table.

A century later, it’s clear the water they bet on is not there. More than two decades of drought, lake evaporation and overuse of water have nearly drained the river’s two anchor reservoirs, Lake Powell on the Arizona-Utah border and Lake Mead near Las Vegas. Climate change is rendering the basin drier, shrinking spring runoff that’s vital for river flows, farms, tribes and cities across the basin – and essential for refilling reservoirs.

The states that endorsed the Colorado River Compact in 1922 – and the tribes and nation of Mexico that were excluded from the table – are now straining to find, and perhaps more importantly accept, solutions on a river that may offer just half of the water that the Compact assumed would be available. And not only are solutions not coming easily, the relationships essential for compromise are getting more frayed.

Chuck Cullom, executive director of the Upper Colorado River Commission. With 25 years of experience working on the Colorado River, Chuck Cullom is used to responding to myriad challenges that arise on the vital lifeline that seven states, more than two dozen tribes and the country of Mexico depend on for water. But this summer problems on the drought-stressed river are piling up at a dizzying pace: Reservoirs plummeting to record low levels, whether Hoover Dam and Glen Canyon Dam can continue to release water and produce hydropower, unprecedented water cuts and predatory smallmouth bass threatening native fish species in the Grand Canyon. 

“Holy buckets, Batman!,” said Cullom, executive director of the Upper Colorado River Commission. “I mean, it’s just on and on and on.”

A Colorado River Tribal Leader Seeks A Voice In the River’s Future–And Freedom to Profit From Its Water
WESTERN WATER Q&A: CRIT Chair Amelia Flores Says Allowing Tribe to Lease Or Store Water Off Reservation Could Aid Broader Colorado River Drought Response and Fund Irrigation Repairs

Amelia Flores, chairwoman of the Colorado River Indian Tribes.As water interests in the Colorado River Basin prepare to negotiate a new set of operating guidelines for the drought-stressed river, Amelia Flores wants her Colorado River Indian Tribes (CRIT) to be involved in the discussion. And she wants CRIT seated at the negotiating table with something invaluable to offer on a river facing steep cuts in use: its surplus water.

CRIT, whose reservation lands in California and Arizona are bisected by the Colorado River, has some of the most senior water rights on the river. But a federal law enacted in the late 1700s, decades before any southwestern state was established, prevents most tribes from sending any of its water off its reservation. The restrictions mean CRIT, which holds the rights to nearly a quarter of the entire state of Arizona’s yearly allotment of river water, is missing out on financial gain and the chance to help its river partners.

New EPA Regional Administrator Tackles Water Needs with a Wealth of Experience and $1 Billion in Federal Funding
WESTERN WATER Q&A: Martha Guzman says surge of federal dollars offers 'greatest opportunity' to address longstanding water needs, including for tribes & disadvantaged communities in EPA Region 9

EPA Region 9 Administrator Martha Guzman.Martha Guzman recalls those awful days working on water and other issues as a deputy legislative secretary for then-Gov. Jerry Brown. California was mired in a recession and the state’s finances were deep in the red. Parks were cut, schools were cut, programs were cut to try to balance a troubled state budget in what she remembers as “that terrible time.”

She now finds herself in a strikingly different position: As administrator of the U.S. Environmental Protection Agency’s Region 9, she has a mandate to address water challenges across California, Nevada, Arizona and Hawaii and $1 billion to help pay for it. It is the kind of funding, she said, that is usually spread out over a decade. Guzman called it the “absolutely greatest opportunity.”

Lower Colorado River Tour 2023
Field Trip - March 8-10

This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.

The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

As the Colorado River Shrinks, Can the Basin Find an Equitable Solution in Sharing the River’s Waters?
WESTERN WATER IN-DEPTH: Drought and climate change are raising concerns that a century-old Compact that divided the river’s waters could force unwelcome cuts in use for the upper watershed

Glen Canyon Dam and Lake Powell, a key Colorado River reservoir that has seen its water level plummet after two decades of drought. Climate scientist Brad Udall calls himself the skunk in the room when it comes to the Colorado River. Armed with a deck of PowerPoint slides and charts that highlight the Colorado River’s worsening math, the Colorado State University scientist offers a grim assessment of the river’s future: Runoff from the river’s headwaters is declining, less water is flowing into Lake Powell – the key reservoir near the Arizona-Utah border – and at the same time, more water is being released from the reservoir than it can sustainably provide.

WESTERN WATER IN-DEPTH: A study of tribal water rights could shed light on future Indian water use

Aerial view of the lower Colorado RiverAs the Colorado River Basin becomes drier and shortage conditions loom, one great variable remains: How much of the river’s water belongs to Native American tribes?

Native Americans already use water from the Colorado River and its tributaries for a variety of purposes, including leasing it to non-Indian users. But some tribes aren’t using their full federal Indian reserved water right and others have water rights claims that have yet to be resolved. Combined, tribes have rights to more water than some states in the Colorado River Basin.

Klamath River Basin

Cropland around Upper Klamath Lake in Oregon

The Klamath River Basin is one of the West’s most important and contentious watersheds.

The watershed is known for its unusual geography straddling California and Oregon. Unlike many western rivers, the Klamath does not originate in snowcapped mountains but rather on a volcanic plateau. 

A broad patchwork of spring-fed streams and rivers in south-central Oregon drains into Upper Klamath Lake and down into Lake Ewauna in the city of Klamath Falls. The outflow from Ewauna marks the beginning of the 263-mile Klamath River.

The Klamath courses south through the steep Cascade Range and west along the rugged Siskiyou Mountains to a redwood-lined estuary on the Pacific Ocean just south of Crescent City, draining a watershed of 10 million acres. 

A bounty of resources – water, salmon, timber and minerals – and a wide range of users turned the remote region into a hotspot for economic development and multiparty water disputes (See Klamath River timeline).

Though the basin has only 115,000 residents, there is seldom enough water to go around. Droughts are common. The water scarcity inflames tensions between agricultural, environmental and tribal interests, namely the basin’s four major tribes: the Klamath Tribes, the Karuk, Hoopa Valley and Yurok. Klamath water-use conflicts routinely spill into courtrooms, state legislatures and Congress. 

In 2023, a historic removal of four powers dams on the river began, signaling hope for restoration of the river and its fish and easing tensions between competing water interests. In February 2024, Interior Secretary Deb Haaland announced a “historic” agreement between tribes and farmers in the basin over chronic water shortages. The deal called for a wide range of river and creek restoration work and modernization of agricultural water supply infrastructure. 

Water Development

Farmers and ranchers have drawn irrigation water from basin rivers and lakes since the late 1900s. Vast wetlands around Upper Klamath Lake and upstream were drained to grow crops. Some wetlands have been restored, primarily for migratory birds.

In 1905, the federal government authorized construction of the Klamath Project, a network of irrigation canals, storage reservoirs and hydroelectric dams to grow an agricultural economy in the mostly dry Upper Basin. The Project managed by the U.S. Bureau of Reclamation irrigates about 240,000 acres and supplies the Lower Klamath Lake and Tule Lake national wildlife refuges managed by the U.S. Fish and Wildlife Service.

Klamath River Basin

Water Management

Since 1992, federal mandates to restore populations of fish protected by the Endangered Species Act have led in some dry years to drastic cuts in water deliveries to Klamath Project irrigators.

Water in Upper Klamath Lake must be kept above certain levels for the endangered shortnose and Lost River suckers. Lake levels and Klamath River flows below Iron Gate Dam also must be regulated for the benefit of threatened coho salmon (See Klamath Basin Chinook and Coho Salmon).

Conflict

In 2001, Reclamation all but cut off irrigation water to hundreds of basin farmers and ranchers, citing a severe drought and legal obligations to protect imperiled fish. In response, thousands of farmers, ranchers and residents flocked to downtown Klamath Falls to form a “bucket brigade” protest, emptying buckets of water into the closed irrigation canal. The demonstrations stretched into the summer, with protestors forcing open the irrigation headgates on multiple occasions. Reclamation later released some water to help farmers.

Karuk fisheries workers netting salmon in Klamath River.In September 2002, a catastrophic disease outbreak in the lower Klamath River killed tens of thousands of ocean-going salmon. The Pacific Coast Federation of Fishermen’s Associations sued Reclamation, alleging the Klamath Project’s irrigation deliveries had violated the Endangered Species Act. The fishing industry eventually prevailed, and a federal court ordered an increase to minimum flows in the lower Klamath.

Compromise

The massive salmon kill and dramatic water shut-off set in motion a sweeping compromise between the basin’s many competing water interests: the Klamath Basin Restoration Agreement and the Klamath Hydroelectric Settlement Agreement. The 2010 agreements included:

  • Removal of four hydroelectric dams
  • $92.5 million over 10 years to pay farmers to use less water, increase reservoir storage and help pay for water conservation and groundwater management projects.
  • $47 million over 10 years to buy or lease water rights to increase flows for salmon recovery.

Dam Removals

Congress never funded the two agreements, allowing the key provisions to expire. The restoration accord dissolved in 2016. The hydroelectric pact, however, was revived in an amended version that did not require federal legislation.

The new deal led to the nation’s largest dam removal project ever undertaken.

The Klamath's Copco No. 2 DamCalifornia and Oregon formed a nonprofit organization called the Klamath River Renewal Corporation to take control of the four essentially obsolete power dams – J.C. Boyle, Copco No. 1, Copco No. 2 and Iron Gate – and oversee a $450 million dam demolition and river restoration project.

Taking out the dams will open more than 420 miles of river and spawning streams that had been blocked for more than a century, including cold water pools salmon and trout need to survive the warming climate.  

Demolition crews took out the smallest dam in 2023 and all four dams were taken down by the end of 2024.

The images of yellow heavy machinery tearing into the dam’s spillway gates prompted a cathartic release for many who have been fighting for decades to open this stretch of the Klamath.

“I’m still in a little bit of shock,” said Toz Soto, the Karuk fisheries program manager. “This is actually happening…It’s kind of like the dog that finally caught the car, except we’re chasing dam removal.”
