Is the Grand Canyon river drying up?

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.

What happens if Lake Mead dries up forever? If Lake Mead were to run out of water, the Hoover Dam would no longer be able to generate power or provide water to surrounding cities and farms. The Colorado River would essentially stop flowing, and the Southwest would be in a major water crisis.

Rainfall doesn't immediately add inches to the nation's largest reservoir. Lake Mead is enormous, and even the storm that dumped 8-10 inches of rain at Mt. Charleston covered a much smaller area than the lake. “We saw Mead's water level tick up a couple tenths of an inch.

Since 1983, years of drought along with high water demand have caused the lake to drop by 132 feet. Today, the lake is at only 30% capacity, its lowest level since it was built in the 1930s. Fortunately, heavy rainfall early in 2023 has relieved the situation a little, but only temporarily.

Lake Tahoe, with its massive 744,600-acre foot storage capacity, should come very close to filling. (The top 6.1 ft. of storage above the lake's rim is used to provide river flows and drought reserves). This is a remarkable rebound for the lake which, in early December, was almost six inches below its natural rim.
