What happens if the Colorado River dries up completely?
If the water levels dip much lower, the Colorado's northernmost reservoir won't have enough in the tank to both fill Lake Mead downstream and generate any hydropower, which would have devastating effects on the electricity grid in the western US.

Without water from the Colorado River, Arizona's gross state product would drop by more than $185 billion in a year and the state would lose more than 2 million jobs, the 2015 report found.
Colorado River crisis is so bad, lakes Mead and Powell are unlikely to refill in our lifetimes. Boaters are dwarfed by a white bathtub ring around Lake Mead.
Climate change, a rising population, and unsustainable consumption of water in the southwest are threatening the very existence of the Colorado River that's been running through the center of the Grand Canyon for six million years.

The climate crisis has caused the ailing Colorado River basin, a system relied upon by 40 million people in the US west, to lose more than 10tn gallons of water in the last two decades, new research has found.
Electricity would not just be the only thing lost. Without Lake Mead, Las Vegas would lose access to 90 percent of its water sources. If Lake Mead were to reach dead pool, it would technically still be able to supply drinking water to Las Vegas. But there will not be enough water for agricultural activities.
The river is about 30 feet deep in lower reaches of the Grand Canyon; it is not more than 10 feet in the upper reaches above the Grand Junction, Colo. Near Lees Ferry, Ariz., the river's rate of flow is about 8 million gallons per minute (gpm); at the mouth it is about 2 million gpm.
California — with the largest allocation of water from the river — is the lone holdout. Officials said the state would release its own plan. The Colorado River and its tributaries pass through seven states and into Mexico, serving 40 million people and a $5 billion-a-year agricultural industry.
Right now, there is only about 7 million acre-feet flowing into the Canyon in 2022. But levels are still declining, and we are getting closer to the point where Glen Canyon Dam cannot generate electricity, and potentially even worse, where water really can't safely flow through the dam at all.
How long does Lake Mead have left? Lake Mead has been facing a water crisis for many years. The water level in the lake has been dropping due to the increasing demand for water and the decreasing supply. If the trend continues, the lake could run out of water in the next 10 to 15 years.
Mead reaches dead pool at 895 feet. If Lake Powell reaches dead pool, the US Bureau of Reclamation—which declined our interview requests—would be unable to meet its obligation to deliver water downstream to Lake Mead. In which case, 40 million people would be affected.
“Although every drop counts, the reality is that the rain we received from Tropical Storm Hilary and runoff into the tributaries that enter Lake Mead as well as reduced releases from Hoover Dam — due to a decrease in downstream demand — has had some minor impact on the lake's elevation,” according to U.S. Bureau of ...
