Where they agree
- Both outlets report that Lake Mead and Lake Powell’s decline, tied to Colorado River shortages, is putting new pressure on Arizona’s water supply.
- Both indicate that federal cuts to Colorado River allocations are expected or already looming.
- Both cite experts saying the practical response involves infrastructure investment rather than immediate taps running dry.
Where they differ
- 12 News focuses broadly on the historic lows at Lake Mead and Lake Powell and their statewide implications for water and power.
- FOX 10 narrows in on a specific case study, Apache Junction, detailing its total dependence on the river and its concrete infrastructure projects.
- FOX 10 includes direct expert commentary from Kathryn Sorensen on rising prices and from city official Brian Draper on groundwater banks and treatment plant upgrades, details absent from the 12 News piece as provided.
Lake Mead and Lake Powell, the two largest reservoirs on the Colorado River, have dropped to historically low levels, intensifying pressure on Arizona’s water and power supplies as federal officials weigh further cuts to the state’s river allocation. Water experts say the shortage won’t cut off tap water for most residents, but it will make water more expensive as cities invest in new infrastructure to reduce their dependence on the river.
How bad are the reservoir levels, and what’s at stake for Arizona?
Lake Mead and Lake Powell, which store Colorado River water and generate hydropower for the Southwest, have fallen to historic lows. That decline adds to strain on a river system that Arizona depends on heavily for both water and electricity, and it raises the odds of additional mandatory cuts to the state’s share of the river in the near future.
Will Arizona residents run out of water?
No, according to Kathryn Sorensen of the Kyle Center for Water Policy at Arizona State University. She said residents should not expect shortages at the tap, but should expect their water bills to rise, especially in cities that lean most heavily on Colorado River supplies, because those cities will need to pay for costly new infrastructure to shore up alternative supplies.
Which Arizona cities are most exposed, and what are they doing about it?
Apache Junction, in Maricopa County, is entirely dependent on Colorado River water for its supply, making it one of the more vulnerable municipalities. Brian Draper, the city’s deputy water director, said Apache Junction has some cushion: unused groundwater supplies and a bank of long-term storage credits stored underground that can be recovered if demand maxes out the river allocation in coming years.
Beyond those reserves, the city is investing directly in infrastructure. It is expanding a water treatment facility from a capacity of 4 million gallons a day to 10 million gallons a day. It also plans to pilot advanced water purification technology that would treat wastewater to drinking-water standards, once it clears permitting with the Arizona Department of Environmental Quality. Draper said scaling up that kind of treatment would let the city put more purified water back into its system and lower its reliance on the river. Despite the looming cuts, Draper said Apache Junction remains open to new development and business, provided newcomers are mindful of how much water they will use, as the fast-growing city tries to balance growth with water-smart planning.
Why does this matter beyond one city?
Apache Junction’s situation illustrates a broader pattern across Arizona municipalities that rely heavily on the Colorado River. As federal officials move to impose cuts tied to the river’s declining reservoirs, cities face a choice between absorbing higher costs to diversify supply — through groundwater, storage credits, treatment plant expansions, and wastewater purification — or risking tighter constraints on growth and development. The costs of that infrastructure are being passed on to residents through higher water rates, even though outright shortages at the tap are not expected in the near term.
What’s not yet clear
The reporting does not specify exact figures for the reservoir declines, a timeline for when new federal cuts might take effect, or how much water rates are expected to rise. It’s also unclear how many other Arizona cities beyond Apache Junction face the same level of total dependence on Colorado River water, though the sources suggest the pressure extends well beyond a single municipality.
