Reports show how water concerns are reaching different parts of the West, from city conservation programs in Arizona to tribal water settlements, drought impacts, and ongoing Colorado River negotiations.

In Arizona, cities are encouraging residents to use less water. SignalsAZ reported that Surprise is offering rebates for eligible water-saving improvements. 12News reported that Scottsdale residents can also receive rebates for conservation upgrades. These programs reflect how cities are trying to reduce demand as Colorado River supplies become less reliable.

Tribal water rights remained a major issue. Navajo Times reported that the Diné water settlement has stalled after objections from Colorado, New Mexico, Utah, and Wyoming. The settlement involves the Navajo Nation, Hopi Tribe, and San Juan Southern Paiute Tribe and is tied to water infrastructure and access in northeastern Arizona. The four Upper Basin states raised concerns about how the water could be used or leased in the future.

Drought impacts continued in Arizona. Congressman Eli Crane’s office reported that the U.S. Department of Agriculture issued drought disaster designations for several Arizona counties. Gila Valley Central reported that Graham and Greenlee counties were declared primary disaster areas because of drought. These designations can make assistance available to eligible farmers and producers.

The University of Arizona Water Resources Research Center released a toolkit for domestic well owners. The guide covers well maintenance, water quality, testing, and drought planning. It is especially relevant for rural residents who rely on private wells.

Water demand from data centers also remained part of the discussion. KTAR reported on concerns over whether data centers are draining Arizona’s water. As technology projects expand, their energy use, cooling needs, and long-term water demand are drawing more attention.

Across the West, drought pressure continued. KSL reported that experts are watching specific regions and industries facing severe drought impacts. Cowboy State Daily reported that an irrigation district in eastern Wyoming warned water could run out by early August.

Colorado River negotiations also remained unsettled. KNPR reported on where Southern Nevada stands as the current river management agreement nears expiration. KLAS reported that Colorado’s water commissioner said drought conversations remain difficult. KUTV reported that Upper and Lower Basin states failed to reach an agreement on Lake Powell.

Weather added more uncertainty. Several outlets reported rising odds of a strong El Niño. While El Niño can bring wetter conditions to some areas, it does not guarantee drought relief for the Colorado River system. Snowpack, runoff, and soil conditions will still determine how much water reaches reservoirs.

The reports show water planning happening on several fronts. Cities are offering rebates, rural residents are receiving well guidance, Arizona counties are facing drought designations, tribes are waiting on settlement progress, and Basin states are still negotiating future river rules. (more…)

Arizona cities are pressing for clearer answers on water they stored underground as the state prepares for possible Colorado River cuts.

KJZZ reported that Phoenix-area cities and the Arizona Water Banking Authority are in disagreement over how stored Colorado River water should be distributed during shortages. Since the late 1990s, excess Colorado River water has been stored underground as a backup supply. With new river rules expected and cuts likely for Central Arizona Project users, cities want to know how much water they will be allowed to recover, when it would be available, and what requirements may come with it.

The question is not just how much water exists underground. It is also how the Water Bank decides who gets access and how much should be saved for future shortages. KJZZ reported that Water Bank officials are considering policies that could limit distribution or require cities to show conservation efforts before receiving stored water.

Scottsdale is also adding to its stored-water portfolio. KJZZ reported that the city approved an $8.25 million purchase of water credits from Harquahala Valley through the Central Arizona Project. The credits represent water stored underground for future use. According to KJZZ, the purchase amounts to about 15,000 acre-feet of water and brings Scottsdale’s long-term water credits to just under 300,000 acre-feet.

The purchase shows how cities are looking beyond current deliveries and preparing for uncertainty. Stored credits can help provide backup during shortages, but they still depend on access, recovery, and long-term management.

Drought conditions are also affecting Arizona counties. Congressman Eli Crane’s office reported that the U.S. Department of Agriculture issued drought disaster designations for several Arizona counties. Gila, Pinal, and Yuma counties were elevated to primary disaster status in a later designation, while other counties were listed as contiguous. The designations can help make agricultural assistance available to eligible producers affected by drought.

Groundwater recharge remains part of the broader water planning conversation. Agri-Pulse reported that California lawmakers are again trying to address permitting delays for groundwater recharge projects. The bill discussed in the report would give farmers and water agencies more flexibility to capture high flows and move water underground when wet conditions allow. Supporters say current permitting can be too slow for short windows of available water.

The issue connects to Arizona’s own recharge discussions. Across the West, water managers are looking at ways to store more water underground during wet periods so communities and farms have more flexibility during dry years.

The legal side of western water also continues to grow. The Colorado Sun reported that the U.S. Supreme Court agreed to hear Nebraska’s lawsuit against Colorado over the proposed Perkins Canal. Nebraska says the canal is needed to bring South Platte River water into Nebraska under a 1923 compact. Colorado officials say the state is complying with the compact and will defend its water rights. (more…)

Arizona’s water coverage centered on a practical question: if the Colorado River keeps shrinking, how much backup water is actually available, and who can use it?

KJZZ reported that Phoenix-area cities are asking for clearer answers about Colorado River water stored underground by the Arizona Water Banking Authority. The Water Bank was created in 1996 to store excess Colorado River water underground for use during a shortage. Cities that rely on the Central Arizona Project say they need to know how much of that stored water they can access, when it would be available, and how it would be recovered.

The issue is becoming more urgent as federal officials consider new Colorado River operating rules. Arizona Farm Bureau News reported that Arizona water officials are pushing for the Lower Basin proposal as an alternative to deeper federal cuts. The proposal includes mandatory reductions across Arizona, California, and Nevada, along with additional voluntary savings through 2028.

The Arizona Farm Bureau also reported that the Central Arizona Project is now projecting a 14% shortage in its municipal water pool instead of 20%, partly by using water from Lake Pleasant and wells in Yuma. Even with that smaller projected shortage, cities and farms are still preparing for less water.

Agriculture remains a major part of the discussion. Arizona farmers are watching possible cuts closely because reductions to Colorado River water can affect planting decisions, crop choices, and operating costs. Those changes can also move beyond farms, reaching workers, local economies, and food supply chains.

Arizona is also looking at how to keep more water in the state. KJZZ reported that more than 95% of precipitation that falls in Arizona is lost to evapotranspiration. The reporting was based on the Arizona Tri-University Recharge and Water Reliability Project, which is studying ways to capture more rain, snowmelt, and runoff before it is lost to evaporation or plant use. The project is also looking at how more water can be moved into aquifers through recharge.

That research connects directly to questions about groundwater. As Colorado River supplies become less reliable, cities and rural areas are paying closer attention to underground storage, recharge, and long-term access to stored water.

The Desert Review reported that the Central Arizona Irrigation and Drainage District secured up to 10,000 acre-feet per year of new water supply from the Mojave Groundwater Bank in California. The agreement is another example of Arizona water users looking outside traditional supplies as Colorado River shortages continue.

Lake Powell also remained under pressure. The Guardian reported that the reservoir could fall to unprecedented lows after poor snowpack and limited spring runoff. KUTV and Newsweek reported on a proposal from scientists to move more water from Lake Powell to Lake Mead, arguing that storing more water in Lake Mead could reduce losses and protect downstream supplies. The idea is part of a larger debate over how the two major reservoirs should be managed as both remain low. (more…)

Lake Powell remained one of the biggest concerns. The Colorado Sun reported that low water levels are creating new pressure at Glen Canyon Dam, where federal officials are working to protect dam infrastructure as the reservoir drops. The report focused on cavitation, a problem caused when fast-moving water creates vapor bubbles that can damage dam equipment and concrete surfaces.

The issue shows how falling reservoir levels affect more than water storage. Lake Powell also supports hydropower generation, downstream releases, and dam operations. When the reservoir drops too low, federal managers have fewer options to move water through the system safely and efficiently.

Arizona water users are also watching federal planning closely. The Arizona Daily Star reported that a Colorado River water savings plan could reduce the effect of future cuts on Arizona users. The plan is part of ongoing Lower Basin negotiations as Arizona, California, and Nevada look for ways to conserve water and avoid deeper mandatory reductions.

Those negotiations remain unsettled. Fox 13 Salt Lake City reported that Colorado River governors said they are not at a stalemate, even as the deadline for new river rules gets closer. The current operating guidelines are set to expire after 2026, and the seven Basin states still need agreement on how future shortages will be shared.

For Arizona, Central Arizona Project water remains a major concern. The CAP canal moves Colorado River water to central and southern Arizona, including cities, farms, and tribal users. If future cuts fall heavily on CAP water, impacts would vary depending on each user’s legal priority, water portfolio, and access to stored supplies.

AMWUA reported on the importance of municipal access to stored water credits. Cities have stored water underground for years to prepare for shortages, but access to those credits becomes more important as Colorado River supplies become less reliable. Stored credits can help cities manage short-term gaps, but they are not a permanent replacement for long-term river reductions.

The idea of moving new water into Arizona also received attention. Some proposals have looked at whether abandoned energy pipelines could be used to bring water west. These ideas reflect the search for new supplies, but large importation projects often involve high costs, legal questions, energy demands, and environmental review. (more…)

Recent developments across the Colorado River Basin show how changes in water supply are beginning to affect recreation, agriculture, and future water planning. While the seven Basin states remain divided over how to manage the river, communities are already dealing with the effects of lower flows and looking at new ways to protect their water.

Colorado River negotiators recently made a rare public appearance together, but there was little indication that the states are closer to an agreement. Representatives from the Upper and Lower basins continue to disagree over how future water reductions should be shared and whether the next plan should offer long-term certainty or act as a temporary bridge.

Nevada negotiator John Entsminger said the latest Lower Basin proposal could provide a workable plan for the next few years and help keep the states out of court while discussions continue. Colorado negotiator Becky Mitchell questioned whether returning to negotiations every two years would build stability or simply create another series of temporary fixes.

The negotiators also discussed mediation as a possible next step. One idea would involve choosing three mediators: one selected by the Upper Basin, another by the Lower Basin, and a third selected by the first two. The ongoing disagreement is also making it difficult for Mexico, which receives Colorado River water under international agreements, to prepare for future shortages.

While those larger negotiations continue, uncertainty is reaching businesses that depend directly on the river. KNAU reported that Grand Canyon rafting companies are watching lower water levels near Lees Ferry following a historically dry winter and reduced releases from Lake Powell.

Rafting trips are still operating, and visitors may not notice a major difference today. However, business owners and river guides are concerned about what lower and less predictable flows could mean in the future. One company reported that bookings were down about 25% this year, although it was unclear whether water conditions were the main reason.

The concern shows how Colorado River operations support more than drinking water, agriculture, and hydropower. Releases from Glen Canyon Dam also affect rafting companies, guides, tourism, and communities connected to Grand Canyon recreation.

Arizona is also looking at less traditional ways to increase its water supply. Voice of San Diego reported that a private utility proposed using Arizona funding to help treat wastewater from the Tijuana River. The water would be treated and returned to Mexico, while Arizona could seek part of Mexico’s Colorado River allocation in exchange.

The proposal could initially produce more than 14,000 acre-feet of water each year, with the possibility of increasing that amount through future development. However, the project is still being studied and would involve complicated questions involving water quality, cost, environmental review, and agreements between the United States and Mexico.

Colorado, meanwhile, has taken action to reduce the damage left behind when agricultural water is sold and transferred to cities. A new state law will require farmland in the Arkansas River Basin to be revegetated before irrigation water can be moved to another use. (more…)

As Colorado River negotiations remain stalled, water leaders across the West are looking beyond temporary reservoir protections and considering broader changes to how water is managed. Recent reports show growing interest in mediation, permanent groundwater conservation, less water-intensive agriculture, and stronger tribal participation in state water decisions.

Representatives from the seven Colorado River Basin states recently addressed criticism over their failure to reach an agreement for managing the river after the current operating rules expire. KJZZ reported that negotiators remain divided over how future reductions should be shared between the Upper and Lower basins, despite more than a year of talks and worsening conditions across the watershed.

The negotiators acknowledged the frustration surrounding the process but maintained that the disagreements involve difficult legal, economic, and hydrological questions. Some state representatives have suggested bringing in a mediator to help narrow the divide. Mediation could provide another path toward compromise, but it would not remove the central dispute over who should reduce water use and by how much.

While the states continue debating Colorado River operations, groundwater is becoming another area of concern. KJZZ examined whether Arizona could establish a program to voluntarily purchase and permanently retire groundwater rights, similar to a program being developed in Nevada. Nevada’s approach would pay willing water-right holders to stop pumping permanently in areas experiencing declining aquifers, threats to groundwater-dependent ecosystems, or conflicts between existing users. An assessment of more than 6,000 Nevada wells found that nearly 40% showed significant declines over several decades.

A similar program could offer Arizona another tool for addressing groundwater depletion, especially in rural basins where pumping can exceed natural recharge. However, the cost of purchasing water rights would vary by location, and a voluntary program would require stable funding and clear priorities. Buying back rights would not restore an aquifer immediately, but it could prevent additional pumping and reduce long-term pressure.

Agriculture is also being asked to adapt to shrinking supplies. The Colorado Sun reported that researchers and farmers are testing crops that require less water, including black-eyed peas and drought-tolerant grains. Black-eyed peas can reach strong production with considerably less water than some traditional crops and can withstand heat without showing the same level of stress.

The challenge is not only whether farmers can grow less-thirsty crops, but whether there is a reliable market for them. Farmers must consider processing, transportation, buyers, and prices before replacing established crops. Water conservation will be difficult to sustain if producers are asked to take on the financial risk alone. Researchers say successful transitions will require partnerships among farmers, universities, buyers, and public agencies.

New reporting also provides a clearer picture of agriculture on California tribal lands. The Public Policy Institute of California found that about 15,800 acres are irrigated annually on tribal reservations in the state, representing roughly 0.2% of California’s irrigated acreage and agricultural water use. Most irrigated tribal acreage is located within the Colorado River Basin.

The report found that tribal agriculture generally has a more balanced mix of crops than agriculture statewide, with fewer permanent orchards and vineyards and a greater share of annual crops, pasture, and vegetables. Because annual crops can be changed more easily from year to year, tribal agricultural operations may have more flexibility during drought. However, tribal producers still face challenges involving infrastructure, financing, water access, and unquantified rights.

California lawmakers are also considering a measure that would strengthen the role of tribes in water policymaking. Assembly Bill 2218 passed the State Assembly and would require certain state agencies to consult affected tribes when reviewing water rights and policies. The bill would also recognize historical inequities caused by state actions that excluded tribes from access to and control over water.

Supporters say existing tribal consultation policies are not always legally secure and can depend on executive decisions. The proposed law would provide a stronger requirement for agencies to consider tribal water uses, Indigenous knowledge, and ecosystem restoration when making water decisions. (more…)
