Topic: Colorado River

Overview April 24, 2014

Colorado River

Colorado RiverServing as the “lifeline of the Southwest,” and one of the most heavily regulated rivers in the world, the Colorado River provides water to 35 million people and more than 4 million acres of farmland in a region encompassing some 246,000 square miles.

From its headwaters northwest of Denver in the Rocky Mountains, the 1,450-mile long river and its tributaries pass through parts of seven states: Arizona, California, Colorado, New Mexico,  Nevada, Utah and Wyoming and is also used by the Republic of Mexico. Along the way, almost every drop of the Colorado River is allocated for use.

The Colorado River Basin is also home to a range of habitats and ecosystems from mountain to desert to ocean.

A $10 billion data center is slated for Horseshoe Bend

Developers in Arizona are planning to build a $10 billion data center next to Horseshoe Bend, an iconic viewpoint along the Colorado River. The 500-acre parcel, located a mile from Horseshoe Bend, was previously protected for outdoor recreation. … A petition to stop the data center’s construction has already netted over 1,800 signatures as of this publication. The document cites concerns over water consumption and contamination, pollution, and an “unsightly blight that will detract from the scenic beauty.” … These servers generate immense heat, and keeping them cool requires a large amount of water, the bipartisan think tank Environmental and Energy Study Institute writes.

Thursday Top of the Scroll: Cox, other governors summoned to DC for Colorado River talks

Governor Spencer Cox said he and his fellow governors of states along the Colorado River have been summoned to Washington D.C. to try to negotiate an agreement. ”I will be going back to D.C., I think towards the end of next week; all the governors are going to be getting together with the Department of Interior to have a discussion there,” Gov. Cox said. … FOX 13 News reached out to the governors offices in several states to see if they intended to participate in the talks. Wyoming Gov. Mark Gordon’s office confirmed he would attend. So did Nevada Gov. Joe Lombardo’s office. … Utah’s governor also expressed support for an idea to pay California to build more desalination plants along the Pacific Coast in exchange for Colorado River water shares upstream.

Big storms needed to make up for Colorado’s record low snowpack

Colorado’s snowpack is at a record low, and the longer that continues, the harder it will be to make up the deficit before the end of winter, water managers say. … This year, the state has about 58% of its normal snowpack — the lowest on record for this time of year. … The northwestern combined basin is part of the larger Colorado River Basin, which spans the Western Slope and extends across six other states and into northern Mexico. If critically dry conditions continue, one of the basin’s massive reservoirs, Lake Powell, could drop so low that it would not be able to generate hydroelectric power by December, according to the Bureau of Reclamation.

Will floating solar solve Utah’s energy and water shortages?

A novel idea to both conserve water and generate power surfaced on Capitol Hill earlier this month. Rep. Hoang Nguyen, D-Salt Lake City, joined representatives with Utah-based Water Wise Solar Solutions, advocating for floating solar panels across Utah water bodies. The panels could help slow evaporation on lakes and reservoirs while also supplementing the grid with some much-needed electricity, Nguyen said. … The company seeks not just to conserve water with solar panels, which could shade waterbodies from the summer heat, but to conserve land for other economic and environmental uses other than sprawling solar farms.

Colorado River talks: States are still at odds but working toward a 5-year plan

With just weeks to decide how to share the Colorado River’s shrinking water supply, negotiators from seven states hunkered down in a Salt Lake City conference room. … The states moved forward on a deal for two-and-a-half days, then went back by almost as far as they’d come, [Utah chief negotiator Gene] Shawcroft said. … Shawcroft reiterated Tuesday what he and his counterparts from the other Colorado River states have said in recent months: They don’t have a deal, but they do have a commitment to keep talking and meet their upcoming February deadline.

Has a gas station near you closed? This California law may be why

… As of Jan. 1, California is mandating that underground fuel tanks have two protective shells to prevent soil or groundwater contamination. The single-walled cylinders at the Bay Farm station are considered archaic and possibly hazardous, prone to leaks like the one that recently caused a major road closure in Burlingame. … According to the State Water Resources Control Board, California has fewer than 650 single-walled tanks left in the ground. … In due time, state water board leaders assure that all of California’s underground gas supply will be doubly secured, their outer layers girded for earthquakes, extreme weather or natural deterioration.

Bennet, Neguse continue calls for review of Uinta Basin Railway project over concerns of potential for oil spills

U.S. Sen. Michael Bennet and Rep. Joe Neguse are continuing their calls for a comprehensive review of the Uinta Basin Railway, a project that would ship crude oil along the headwaters of the Colorado River. … Bennet, Neguse and environmental groups have raised concerns that the project could increase the risk of a train derailing and spilling oil into the Colorado River headwaters. … “These trains would run for over 100 miles directly alongside the headwaters of the Colorado River — a vital water supply for nearly 40 million Americans, 30 tribal nations, millions of acres of agricultural land, and a main driver of our state’s recreation and tourism industries,” the lawmakers wrote.

Tuesday Top of the Scroll: Colorado River states face last-ditch effort to agree on shortages

Negotiators for the seven states that share the shrinking Colorado River met in Salt Lake City but could not agree on a deal to split up the water, Arizona’s lead negotiator said. … Talks that ran through most of the week don’t seem to have improved the outlook for a water pact. “I didn’t see enough progress,” Arizona Water Resources Director Tom Buschatzke said on Friday, Jan. 16, “or any major progress” suggesting a deal is imminent.

Much of the West is having its warmest winter on record — and it’s fueling a snow drought

… A lack of snow — known as a snow drought — grips much of the West as a result of the unusually high temperatures, even as winter reaches the midway point. Snow cover was less extensive than any Jan. 14 on record across the West, according to satellite-based measurements. … In California, the snowpack is proportionally worse below 6,500 feet than atop mountain peaks. While most Sierra ski resorts are at high elevations, low-elevation snow is critical for the ecosystem and water resources because it accounts for a larger area. … Drought conditions, while much improved in California, plague a third of the West, according to the U.S. Drought Monitor. The most extreme drought is concentrated in the headwaters of the Colorado River, which drains into Lake Powell and Lake Mead.

One Colorado River option doesn’t require state input. And it could still crash the system.

… As Colorado River rules near expiration, the federal government published Jan. 9 a long-anticipated menu of options for how to replace them and manage the overstressed river basin going forward. … But only one of the possible management plans shows what the Bureau of Reclamation currently has the legal authority to do without approval from the seven basin states, according to the report. And the state negotiators have been at an impasse for nearly two years. That option, called the basic coordination alternative, calls for moderate water cuts in the driest years and would only work for the short term, according to the 1,600-page draft report, called an environmental impact statement, or EIS.

Colorado River states have just weeks to strike a deal. Here’s why it’s so hard for them to agree.

… The seven basin states only have until February 14 to come up with a plan for how to manage the river in dry times. The current guidelines expire at the end of the year. If they test their luck and fail to reach an agreement, they risk the Interior Department making a plan for them or years of litigation. The seven state negotiators are meeting for four days in Salt Lake City this week as they work to hash out a deal before that deadline. … The bureau released a draft environmental impact statement on Friday that lays out a series of pathways to manage the river system and its major reservoirs. If the states reach a deal, the bureau says it will insert that plan as the preferred way forward. … If states can’t agree, the federal government will choose an alternative itself.

Low reservoir levels main cause of toxic algae in Blue Mesa

… A study released in December by scientists at the U.S. Geological Survey and the National Park Service said the main driver for recent toxic harmful algal blooms in Blue Mesa [in Gunnison County, Colo.] is low reservoir levels, which create shallow and warm conditions favorable for algal growth. … This year’s low snowpack and dismal projections mean there could be more releases from Blue Mesa in the future and, therefore, increased potential for more harmful algal blooms. In December, officials from the U.S. Bureau of Reclamation said releases from the three reservoirs — known as the Colorado River Storage Project Act reservoirs or the Upper Initial Units — are one of the tools the federal agency could use to prop up levels at Lake Powell to protect the ability to make hydropower at Glen Canyon Dam.

Feds publish possible playbook for managing dwindling Colorado River supply

The federal agency overseeing the water supply for tens of millions of people in the West has published a list of options for how it might manage the drought-stricken Colorado River in the future. The five proposals range from taking “no action” to a scenario that might result in water cuts to the lower basin states of California, Nevada and Arizona. One alternative developed in partnership with conservation groups would incentivize states and water users to proactively conserve the river. But the Interior Department is not identifying a preferred option, and the scenarios outlined in hundreds of pages of documents will only move forward if all seven states that depend on the water fail to agree on their own conservation plan soon.

Forever chemicals and pharma drugs found in Grand Canyon

The Grand Canyon is one of the world’s most famous waterways, and its stretch of the Colorado River and its tributaries are protected. But a new study has discovered that some of the canyon’s water systems may contain pharmaceutical drugs and forever chemicals. … Monument Spring, which feeds into the Colorado River, showed traces of multiple pharmaceutical medications, including an antibiotic, antifungal, antidepressant, and a diabetic drug. The amounts are small, but experts say the findings indicate wastewater from a nearby treatment plant is somehow seeping back to the canyon and the Colorado River, a major water source for plants, animals, and humans in the region.

Monday Top of the Scroll: Colorado River plan could bring sweeping water cuts to California

The 1,600-page report marks a pivotal moment in negotiations among seven states, 30 tribal nations, Mexico, and a host of stakeholders who rely on the river’s dwindling supply. … California, which draws 4.4 million acre-feet annually from the Colorado River, faces potential cuts of up to 3.9 million acre-feet per year under some scenarios, according to the Bureau’s analysis. That could hit Southern California cities and Imperial Valley agriculture hardest.

The western US is in a snow drought, raising fears for summer water supplies

… Utah is in a snow drought and it’s not alone: Much of the vast, mountainous West is missing its lifeblood — fueled by record-hot temperatures so far this winter. California’s Sierra Nevada Mountains, only recently pasted with heavy snow from atmospheric river storms, are the exception. And while this is an immediate problem for businesses and active outdoors fans, experts are also worried about bigger implications in the near future. If the trend continues, it could deepen the West’s long drought, aggravating already contentious negotiations about allocating water along the Colorado River.

Wednesday Top of the Scroll: Deadlocked Colorado River negotiators to meet, ’sequestered’

Top water officials from the seven Colorado River Basin states will return to the negotiating table next week, reportedly in sequestered fashion, to try to make headway over how to cut water use. Starting Monday, the negotiators will meet for four days in Salt Lake City, sources said, and two people familiar with the long-stalled talks say attendance will be sharply or at least unusually limited. Federal officials are convening the seven-state meeting after a missed deadline in November in the long stalemate over how to deal with the oversubscribed, dwindling river. The U.S. Interior Department, which typically runs the negotiating sessions, has told the states it wants an agreement among them by Feb. 14.

At Lake Powell, engineering is outpacing Colorado River policy

Arizona’s Lake Powell is in trouble. U.S. Bureau of Reclamation modeling shows the reservoir dropped roughly 36 ft between December 2024 and December 2025, a decline that is no longer a warning but an operating condition engineers are designing around. The drop is compressing the margin between routine operations and hard infrastructure limits at Glen Canyon Dam as negotiations over post-2026 Colorado River operating rules remain unresolved. … Basin representatives have asked Reclamation to evaluate protecting Lake Powell elevations near 3,490 ft and to study infrastructure modifications that would allow releases below that level. Any such work would represent a new class of climate-driven capital investment at one of the federal government’s most critical water and power assets.

Despite Calif. rains, America’s largest reservoir remains in peril

… Data from the U.S. Bureau of Reclamation shows that the water elevation at Lake Mead’s Hoover Dam was 1,062.24 feet at the end of December. That’s the lowest it’s been during this time of the year since 2022, when it was 1,044.82 feet. Before that, levels were the lowest in 1936, when the region experienced a severe drought. Lake Mead stored 8.59 million acre-feet of water on Dec. 31, according to USBR data. The lake can store about 26 million acre-feet of water, meaning it was only about 33% full at the end of the year.

No buyers for San Diego water … yet

San Diego arrived in Las Vegas this week ready to sell off some of its excess water at negotiations over the dwindling Colorado River between the states, tribes and farmers who use it. They left without a deal in place. Dan Denham, the San Diego County Water Authority’s general manager, has been hinting there’s willing buyers of San Diego’s expensive desalinated ocean water in the state of Arizona. Arizona is first in line to have their Colorado River supply cut off during water shortages. That very scenario is what the annual Las Vegas negotiations were set up to prevent.

Shoshone pact secures Colorado flows through Grand County

When the Colorado Water Conservation Board voted unanimously last month to approve the $99 million purchase of the Shoshone water rights from Xcel Energy, Western Slope communities called it a “once-in-a-lifetime” deal. In Grand County, the decision lands closer to home. For people living at the headwaters of the Colorado River, it’s a promise that water will keep flowing west, offering a safeguard for ranchers, recreation businesses and the river itself. … By securing them permanently for instream flows, the Colorado River District and its partners ensured that water will continue downstream even if the aging plant shuts down.

Takeaways from Colorado River Water Users Association conference

… The single most important gathering of Colorado River Basin officials came and went — with no significant announcements regarding the often frustrating yet crucial seven-state negotiations for how to divvy up the river over the next 20 years. … Experts said at the three-day Colorado River Water Users Association conference that if meaningful conservation doesn’t happen in states both upstream and downstream, leaders in the West could be headed for remarkably hard decisions about the future. Governors and negotiators from the seven states have an open invitation to the nation’s capital, where Interior Secretary Doug Burgum has indicated he would like to have a joint meeting. Nevada Gov. Joe Lombardo asked Burgum this month to schedule it for January.

December water forecast a sobering backdrop to Colorado River conference

… On Monday, the U.S. Bureau of Reclamation released its monthly report, which projects a two-year hydrology outlook for the operation of the nation’s two largest reservoirs: Lake Powell and Lake Mead. … With the slow start to winter in the Upper Basin (Colorado, New Mexico, Utah and Wyoming), the report showed a drop in Lake Powell’s projected 2026 inflow of 1 million acre-feet since the November forecast. Under the “minimum” possible inflow, Lake Powell would fall below the surface-elevation level of 3,490 feet needed to generate hydropower by October 2026 and stay there until spring runoff briefly bumps up reservoir levels in summer 2027; but the water level would again dip below 3,490 in the fall of 2027.

Stewards of Colorado’s sweetest crops on high alert as invasive mussels gain ground in water supply

… On [peach farmer Rob] Talbott’s farm, water pumps move almost 200 gallons per minute to the thirsty crops on his 145 acres. This year, a new threat is approaching that water system. And it’s microscopic. Invasive zebra mussels have now infested at least 135 miles of the Colorado River, from the Utah border to Dotsero in western Colorado. That includes the stretch that meanders alongside Talbott’s orchards in Palisade. And if these tiny pests flow into his narrow irrigation pipes and tubes, they threaten to mature and block his most precious farming ingredient. These mussels rapidly multiply. A single female lays up to 30,000 eggs. And when they reach adulthood, their sharp shells can wreak havoc on water infrastructure.

Mexicali farmers threaten to use their Colorado River water, putting Tijuana’s supply in jeopardy

If Mexicali farmers can’t cut a deal with Mexican President Claudia Sheinbaum’s administration, the city of Tijuana’s at risk of losing its water supply from the Colorado River.  For generations, these farmers – known as Irrigation District 14 – sold river water the Mexican government ceded to them for agricultural production to coastal cities like Tijuana and Ensenada. The Colorado River flows through Mexicali, but because of this deal, it’s diverted over 100 miles the coast via an aqueduct. But Mexico’s president has taken a hard stance on how the country’s constitution defines ownership of water: It belongs to the nation and cannot be privatized.

Colorado River deal could make or break crucial wetland habitats

The rusty observation tower at the edge of this wastewater-fed marsh offers an osprey-eye view of two possible futures for the parched and overworked Colorado River. To one side, the marsh spreads across more than 20 square miles of pools and islands choked with cattails and phragmites. … On the tower’s other side, boundless flats of sand and cracked mud spread to the horizon across what was, prior to the river’s damming a century ago, one of Earth’s great green estuaries. … The challenges are tremendous all along the Southwest’s most critical river, one that supplies water to 40 million people and feeds millions more.

California water managers advise multipronged approach in face of climate change

State water management officials must work more closely with local agencies to properly prepare California for the effects of climate change, water scientists say. Golden State officials said in the newly revised California Water Plan that as the nation’s most populous state, California is too diverse and complex for a singular approach to manage a vast water network. On Monday, they recommended expanding the work to better manage the state’s precious water resources — including building better partnerships with communities most at risk during extreme drought and floods and improving critical infrastructure for water storage, treatment and distribution among different regions and watersheds.

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?

Utah looks to other states for more water under new bill

A much-anticipated water bill brought by one of the most powerful lawmakers on Capitol Hill became public Thursday. Senate President Stuart Adams’s SB 211, titled “Generational Water Infrastructure Amendments,” seeks to secure a water supply for decades to come. It forms a new council comprised of leadership from the state’s biggest water districts that will figure out Utah’s water needs for the next 50 to 75 years. It also creates a new governor-appointed “Utah Water Agent” with a $1 million annual budget that will “coordinate with the council to ensure Utah’s generational water needs are met,” according to a news release. But combing through the text of the bill reveals the water agent’s main job will be finding an out-of-state water supply. … The bill also notes the water agent won’t meddle with existing water compacts with other states on the Bear and Colorado rivers.

Atmospheric rivers bring rain and snow, but will they feed the Colorado River?

The attention is on Southern California right now, but an atmospheric river’s path will extend inland with potential flooding — and possible drought relief. If you’re watching the weather, it’s still a little early to tell whether these storms will go where they can hope Las Vegas the most. That’s anywhere in the Upper Colorado River Basin, where there’s a chance they could produce snow to help the river that supplies 90% of the water used in Southern Nevada. … The paths of this year’s atmospheric rivers are unlike the ones that slammed the Sierras last year. Those storms carried snow straight east through Northern Nevada and Utah, feeding the Rocky Mountains with snowpack levels that reached 160% of normal by the end of winter.

Commentary: Water regulation in Arizona has now devolved into a game of chicken

Water regulation in Arizona has devolved into a game of chicken. The governor and farmers are rivals revving their engines, hoping their opponent will flinch first. Caught in the middle is Gila Bend, a groundwater basin south of Buckeye, where the state could decide to impose its most stringent form of regulation, whether folks like it or not. Both sides are using Gila Bend as a bargaining chip to win support for competing legislative proposals. But to what end?

Colorado Senate favors limiting nonfunctional turf

Colorado legislators in 2022 passed a bill that delivered $2 million to programs across the state for removal of turf in urban areas classified as nonfunctional. By that, legislators mean Kentucky bluegrass and other thirsty-grass species that were meant to be seen but rarely, if ever, otherwise used. Now, they are taking the next step. The Colorado Senate on Tuesday, Jan. 30 voted in favor of a bill, Senate Bill 24-005, that would prevent thirsty turf species from being planted in certain places that rarely, if ever, get foot traffic, except perhaps to be mowed.

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.

For as long as he can remember, Rob Sowby has heard people call Utah the second-driest state in the nation. Over the years, that claim has become nearly inescapable, echoed by everyone from state departments, city governments and water conservancy districts to national news outlets without a clear citation for what data it’s based on. … Now a Brigham Young University civil engineering assistant professor focused on sustainable water supplies, he decided to get to the bottom of it. Using precipitation data, he found that Utah is actually the nation’s third-driest state, behind Nevada and Arizona.

Upper Colorado River States Add Muscle as Decisions Loom on the Shrinking River’s Future
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.

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.

The Colorado River threading its way through a desert canyon near Lee Ferry, Arizona. Practically every drop of water that flows through the meadows, canyons and plains of the Colorado River Basin has reams of science attached to it. Snowpack, streamflow and tree ring data all influence the crucial decisions that guide water management of the iconic Western river every day.

Could “Black Swan” Events Spawned by Climate Change Wreak Havoc in the Colorado River Basin?
WESTERN WATER NOTEBOOK: Scientists say a warming planet increases odds of extreme drought and flood; officials say they’re trying to include those possibilities in their plans

Runoff from what some describe as an "epic flood" in 1983 strained the capacity of Glen Canyon Dam to convey water fast enough.  The Colorado River Basin’s 20 years of drought and the dramatic decline in water levels at the river’s key reservoirs have pressed water managers to adapt to challenging conditions. But even more extreme — albeit rare — droughts or floods that could overwhelm water managers may lie ahead in the Basin as the effects of climate change take hold, say a group of scientists. They argue that stakeholders who are preparing to rewrite the operating rules of the river should plan now for how to handle these so-called “black swan” events so they’re not blindsided.

A Rancher-Led Group Is Boosting the Health of the Colorado River Near Its Headwaters
WESTERN WATER SPOTLIGHT: A Colorado partnership is engaged in a river restoration effort to aid farms and fish habitat that could serve as a model across the West

Strategic placement of rocks promotes a more natural streamflow that benefits ranchers and fish. High in the headwaters of the Colorado River, around the hamlet of Kremmling, Colorado, generations of families have made ranching and farming a way of life, their hay fields and cattle sustained by the river’s flow. But as more water was pulled from the river and sent over the Continental Divide to meet the needs of Denver and other cities on the Front Range, less was left behind to meet the needs of ranchers and fish.

“What used to be a very large river that inundated the land has really become a trickle,” said Mely Whiting, Colorado counsel for Trout Unlimited. “We estimate that 70 percent of the flow on an annual average goes across the Continental Divide and never comes back.”

150 Years After John Wesley Powell Ventured Down the Colorado River, How Should We Assess His Legacy in the West?
WESTERN WATER Q&A: University of Colorado’s Charles Wilkinson on Powell, Water and the American West

We have an unknown distance yet to run, an unknown river to explore. What falls there are, we know not; what rocks beset the channel, we know not; what walls ride over the river, we know not. Ah, well! We may conjecture many things.

~John Wesley Powell

Explorer John Wesley Powell and Paiute Chief Tau-Gu looking over the Virgin River in 1873.Powell scrawled those words in his journal as he and his expedition paddled their way into the deep walls of the Grand Canyon on a stretch of the Colorado River in August 1869. Three months earlier, the 10-man group had set out on their exploration of the iconic Southwest river by hauling their wooden boats into a major tributary of the Colorado, the Green River in Wyoming, for their trip into the “great unknown,” as Powell described it.

With Drought Plan in Place, Colorado River Stakeholders Face Even Tougher Talks Ahead On The River’s Future
WESTERN WATER IN-DEPTH: Talks are about to begin on a potentially sweeping agreement that could reimagine how the Colorado River is managed

Lake Mead, behind Hoover Dam, shows the effects of nearly two decades of drought. Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.

Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.

Imported Water Built Southern California; Now Santa Monica Aims To Wean Itself Off That Supply
WESTERN WATER SPOTLIGHT: Santa Monica is tapping groundwater, rainwater and tighter consumption rules to bring local supply and demand into balance

The Santa Monica Urban Runoff Recycling Facility (SMURRF) treats dry weather urban runoff to remove pollutants such as sediment, oil, grease, and pathogens for nonpotable use.Imported water from the Sierra Nevada and the Colorado River built Southern California. Yet as drought, climate change and environmental concerns render those supplies increasingly at risk, the Southland’s cities have ramped up their efforts to rely more on local sources and less on imported water.

Far and away the most ambitious goal has been set by the city of Santa Monica, which in 2014 embarked on a course to be virtually water independent through local sources by 2023. In the 1990s, Santa Monica was completely dependent on imported water. Now, it derives more than 70 percent of its water locally.

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.

Domino Effect: As Arizona Searches For a Unifying Voice, a Drought Plan for the Lower Colorado River Is Stalled
EDITOR'S NOTE: Finding solutions to the Colorado River — or any disputed river —may be the most important role anyone can play

Nowhere is the domino effect in Western water policy played out more than on the Colorado River, and specifically when it involves the Lower Basin states of California, Nevada and Arizona. We are seeing that play out now as the three states strive to forge a Drought Contingency Plan. Yet that plan can’t be finalized until Arizona finds a unifying voice between its major water players, an effort you can read more about in the latest in-depth article of Western Water.

As Colorado River Levels Drop, Pressure Grows On Arizona To Complete A Plan For Water Shortages
WESTERN WATER IN-DEPTH: A dispute over who speaks for Arizona has stalled work with California, Nevada on Drought Contingency Plan

Hoover Dam and Lake Mead

It’s high-stakes time in Arizona. The state that depends on the Colorado River to help supply its cities and farms — and is first in line to absorb a shortage — is seeking a unified plan for water supply management to join its Lower Basin neighbors, California and Nevada, in a coordinated plan to preserve water levels in Lake Mead before they run too low.

If the lake’s elevation falls below 1,075 feet above sea level, the secretary of the Interior would declare a shortage and Arizona’s deliveries of Colorado River water would be reduced by 320,000 acre-feet. Arizona says that’s enough to serve about 1 million households in one year.

A Colorado River Raft Trip Offers a Firsthand Lesson in the Power of Nature
ON THE ROAD: Writer Gary Pitzer offers a sense of the Grand Canyon that was first explored by John Wesley Powell

Writer Gary Pitzer at the Grand CanyonMost people see the Grand Canyon from the rim, thousands of feet above where the Colorado River winds through it for almost 300 miles.

But to travel it afloat a raft is to experience the wondrous majesty of the canyon and the river itself while gaining perspective about geology, natural beauty and the passage of time.

Beginning at Lees Ferry, some 30,000 people each year launch downriver on commercial or private trips. Before leaving, they are dutifully briefed by a National Park Service ranger who explains to them about the unique environment that awaits them, how to keep it protected and, most importantly, how to protect themselves.

They also are told about the pair of ravens that will inevitably follow them through the canyon, seizing every opportunity to scrounge food.

Despite Above-Average Snowfall in the Rockies, Lower Colorado River Likely to Remain in Drought
Experts will update you on the latest conditions and forecasts during our three-day tour

Since 2000, the Colorado River Basin has experienced an historic, extended drought causing reservoir storage in the Colorado River system to decline from nearly full to about half of capacity. For the Lower Basin, a key point has been to maintain the level of Lake Mead to prevent a shortage declaration.

A healthy snowfall in the Rockies has reduced the odds of a shortage this year, but the basin states still must come to terms with a static supply and growing demands, as well as future impacts from climate change.

The dramatic decline in water levels in Lake Mead and Lake Powell is perhaps the most visible sign of the historic drought that has gripped the Colorado River Basin for the past 16 years. In 2000, the reservoirs stood at nearly 100 percent capacity; today, Lake Powell is at 49 percent capacity while Lake Mead has dropped to 38 percent. Before the late season runoff of Miracle May, it looked as if Mead might drop low enough to trigger the first-ever Lower Basin shortage determination in 2016.

The article – delayed to include the latest information from Babbitt’s Dec.

Can California Make the 4.4 Plan Work?
March/April 2003

With passage of the original Dec. 31, 2002, deadline to have a Quantification Settlement Agreement (QSA) in place for the Colorado River, California suffered a cutback in the surplus Colorado River flows it had relied upon by years. Further negotiations followed in an attempt to bring the California parties to an agreement. This issue examines the history leading to the QSA, the state of affairs of the so-called 4.4 Plan as of early March, and gives readers a clearer crystal ball with which to speculate about California’s water future on the Colorado River.

Salton Sea

As part of the historic Colorado River Delta, the Salton Sea regularly filled and dried for thousands of years due to its elevation of 237 feet below sea level.

The most recent version of the Salton Sea was formed in 1905 when the Colorado River broke through a series of dikes and flooded the seabed for two years, creating California’s largest inland body of water. The Salton Sea, which is saltier than the Pacific Ocean, includes 130 miles of shoreline and is larger than Lake Tahoe.

Quantification Settlement Agreement

Lining the All-American Canal

The Quantification Settlement Agreement (QSA), signed in 2003, defined the rights to a portion of Colorado River water for the San Diego County Water Authority, Coachella Valley Water District, Imperial Irrigation District and the Metropolitan Water District of Southern California.

The QSA responded to California consistently using more than its annual Colorado River entitlement of 4.4 million acre-feet. Additionally, the water needs of six other Colorado River Basin states had grown, making the river’s shared use increasingly crucial.

Colorado River Water and Mexico

The Mexican Water Treaty of 1944 committed the U.S. to deliver 1.5 million acre-feet of water to Mexico on an annual basis, plus an additional 200,000 acre-feet under surplus conditions. The treaty is overseen by the International Boundary and Water Commission.

Colorado River water is delivered to Mexico at Morelos Dam, located 1.1 miles downstream from where the California-Baja California land boundary intersects the river between the town of Los Algodones in northwestern Mexico and Yuma County, Ariz.

Colorado River Delta (in Mexico)

The Colorado River Delta is located at the natural terminus of the Colorado River at the Gulf of California, just south of the U.S.-Mexico border. The desert ecosystem was formed by silt flushed downstream from the Colorado and fresh and brackish water mixing at the Gulf.

The Colorado River Delta once covered 9,650 square miles but has shrunk to less than 1 percent of its original size due to human-made water diversions.

Colorado River Water Use 4.4 Plan

California’s Colorado River Water Use Plan (known colloquially as the 4.4 Plan) intends to wean the state from its reliance on the surplus flows from the river and return California to its annual 4.4 million acre-feet basic apportionment of the river.

In the past, California has also used more than its basic apportionment.  Consequently, the U.S. Department of Interior urged California to devise a plan to reduce its water consumption to its basic entitlement.

Colorado River 2007 Interim Guidelines And Drought Contingency Plans

In 2005, after six years of severe drought in the Colorado River Basin, federal officials and representatives of the seven basin states — California, Arizona, Nevada, New Mexico, Colorado, Utah and Wyoming — began building a framework to better respond to drought conditions and coordinate the operations of the basin’s two key reservoirs, Lake Powell and Lake Mead.

The resulting Interim Guidelines for Lower Basin Shortages and the Coordinated Operations for Lake Powell and Lake Mead (Interim Guidelines) identified the conditions for shortage determinations and details of coordinated reservoir operations. The 2007 Interim Guidelines remain in effect through Dec. 31, 2025.

“In the West, when you touch water, you touch everything.” – Rep. Wayne Aspinall, D-Colorado, chair, House Interior and Insular Affairs Committee, 1959-1973

Rapid population growth and chronic droughts could augur dramatic changes for communities along the lower Colorado River. In Arizona, California and Nevada, a robust economy is spurring communities to find enough water to sustain the steady pace of growth. Established cities such as Las Vegas and Phoenix continue their expansion but there is also activity in smaller, rural areas on Arizona’s northwest fringe where developers envision hundreds of thousands of new homes in the coming decades.

Jul/Aug 2005

With interstate discussions of critical Colorado River issues seemingly headed for stalemate, Secretary of the Interior Gale Norton stepped in May 2 to defuse, or at least defer, a potentially divisive debate over water releases from Lake Powell. In a letter to governors of the seven Colorado River Basin states, Norton preserved the status quo of river operations for five months, giving states and stakeholders a chance to move back from the edge before positions had hardened on two key issues: (1) shortage guidelines for the Lower Basin and (2) Upper Basin/ Lower Basin reservoir operations, particularly at Lake Powell. But Norton served notice that she wants discussions on those two issues to continue, possibly outside of the annual operation plan (AOP) consultation process, which at least one observer described as unwieldy.

The Colorado River: Coming to Consensus
Mar/Apr 2002

The situation is true anywhere: when resources are stretched, tensions rise. In the arid Southwestern United States, this resource is water and tensions over it have been ever present since the westward migration in the 18th Century. Nowhere in this region has the competition for water been fiercer than in the Colorado River Basin. Whether it is more water for agriculture, more water for cities, more water for American Indian tribes or more water for the environment – there is a continuous quest by parties to obtain additional supplies of this “liquid gold” from the Colorado River. Sometimes the avenue chosen to acquire this desert wealth is the court system, as exemplified by the landmark Arizona v. California dispute that stretched for over 30 years.
