California Power Rates and Colorado River Water Levels Both Face Pressure

Pacific Gas & Electric customers in California may face annual electricity rate increases of several hundred dollars while water supplies from the Colorado River also face pressure. Lake Powell, the reservoir on the Utah-Arizona border, reached its lowest recorded level for early summer after winter precipitation failed to refill the lake.

Federal projections indicate the reservoir could drop to the minimum power pool level as soon as next year, at which point Glen Canyon Dam would stop generating hydroelectric power.

Powell regulates releases into Lake Mead, the source that supplies water to Southern California cities, the Imperial and Coachella valleys, and roughly 40 million people across the western United States. California receives about 4.4 million acre-feet of Colorado River water each year.

The reservoir currently holds 23 percent of capacity and sits more than 170 feet below full level, with projected inflows at roughly half the historical average. Officials from California, Arizona, and Nevada have proposed conserving up to 3.2 million acre-feet through 2028 using mandatory reductions and voluntary programs tied to reservoir levels.

A 2025 UCLA study found that water bills in Los Angeles County have risen nearly 60 percent over the past decade, exceeding inflation and adding pressure on lower-income households. Proposed conservation steps could require hundreds of thousands of acre-feet in cuts for California, payments to farmers to leave land fallow, and additional mandates.

Even a wet winter would provide only temporary relief without addressing the long-term gap between supply and demand, federal water managers stated in recent projections.
