Once designed to stabilize water deliveries to the Lower Basin, the Glen Canyon dam is now becoming a liability due to declining water levels caused by record breaking drought. The reservoir is less than a quarter full, and inflows are projected to be among the lowest ever recorded, driven by unusually early heat and a collapsing snowpack. The dam’s infrastructure was never designed to function at such low elevations, and as water levels drop, the systems that releases water downstream has become unreliable and even dangerous to operate.
This vulnerability could disrupt legally required flows under the 1922 Colorado River Compact, which is an agreement that divides the river’s water between the Upper and Lower Basin states. According to the compact, the Upper Basin States are required by law to provide a fixed amount of water flow annually. This has become an increasingly difficult task to fulfill due to the extreme drought.
The Bureau of Reclamation and other federal entities are attempting short-term emergency measures, such as holding back water in Lake Powell and releasing additional water from upstream reservoirs like Flaming Gorge. However, these actions are described as temporary “triage” that shift risk rather than solve it. This could lower levels in downstream reservoirs like Lake Mead and creating new ecological and economic problems. Long-term solutions, including major engineering retrofits to the dam, are being studied but will require years, congressional approval, and significant funding.
Cities across Arizona, with Phoenix leading the charge, are actively preparing for a future with less Colorado River water. Roughly 40% of Phoenix’s water supply comes from the Colorado River, and officials are anticipating bigger federal cuts around the corner. In response, the city is expanding groundwater access, storing water underground, investing in infrastructure to move water across regions, and developing advanced purification systems that can turn wastewater into drinking water. Programs like the Secure Water Arizona Program (SWAP) aim to create cooperative, market-like exchanges between cities to share water more efficiently. Despite decades of preparation and reduced per-capita water use, officials acknowledge that worsening drought conditions, stalled interstate negotiations, and federal policy decisions are pushing the system toward more restrictive measures, including potential Stage 2 drought warnings with conservation requirements and rising costs for consumers.
Smaller communities, however, are far more exposed to these risks. The example of Cave Creek illustrates how dependent some areas are on the Colorado River, with up to 95% of its water supply coming from the Central Arizona Project canal. Proposed federal cuts possibly exceeding 50%, would have immediate and severe consequences. Unlike larger cities, smaller towns often lack accessible groundwater reserves, forcing them to rely on complex and costly solutions such as water exchanges with neighboring cities or long-distance infrastructure projects. These measures may bring short term stability, but long-term solutions are uncertain, expensive, and legally complicated. The situation highlights a growing divide between large urban systems with resources to adapt and smaller communities that are increasingly vulnerable.
Compounding these supply challenges is rising demand and new forms of water consumption, particularly from industrial development. The expansion of large-scale data centers in California represents a significant emerging pressure on regional water systems. Individual facilities can require hundreds of thousands to over a million gallons of water per day for cooling, placing additional strain on already stressed municipal supplies. While some developers propose using recycled or non-potable water, regulatory gaps and limited transparency around water usage have raised concerns among residents and policymakers. These developments highlight a broader issue: water scarcity in the West is no longer just a natural resource problem but an infrastructure and allocation issue, where competing demands from cities, agriculture, industry, and ecosystems must be balanced under increasingly constrained conditions.
What does this mean for CRIT? As challenges across the Colorado River Basin continue to intensify, Tribal Council has been working to ensure CRIT has a seat at the table during critical water negotiations. Through a more than 100-page comment letter submitted by the Tribe’s lead water attorney, John Bezdek, along with the implementation of the Tribe’s Water Code, the Personhood Resolution for the Colorado River, and the Water Resiliency Act, CRIT continues to strengthen and assert protections for the river as one of its oldest stewards.
