Damn Dam Damage Could Affect Lake Mead Water Levels
As of the writing of this article, the water level at Lake Mead stands at 1,074.18 feet and slowly but surely sinking. While higher than the last two years, it pales compared to the years prior. Well, news of Glen Canyon Dam damage upstream on the Colorado River is giving us a sinking feeling in Southern Nevada.
The Bureau of Reclamation released the result of inspections on the Glen Canyon Dam, which helps hold back Lake Powell. Those inspection show an issue with the pipes that are part of the “river outlet works”. In April of 2023, those pipes sent millions of gallons of water rushing down the Colorado River at once to help build up the beaches that were eroding around the river.
The pipes are showing evidence of a phenomenon called “cavitation”. That cavitation can create shock waves that could do some severe damage to the machinery at the dam.
How Does Glen Canyon Dam Damage Affect Southern Nevada
What does the Glen Canyon Dam damage matter to us? After all, it is 270 miles east of Las Vegas. Why worry?
Well, things unfortunately get complicated when it comes to water coming downstream. We’ve gotten occasional deluges of water coming down the Colorado River. Those waves came down thanks in part to large water release events from Lake Powell. That water went down those damaged pipes.
According to the executive director of the Utah Rivers Council “the archaic plumbing inside Utah’s Glen Canyon Dam is the most urgent water problem facing the 40 million people of the Colorado River Basin.” Yikes.
Right now, Lake Powell sits at 3,558 feet. If it dips below 3,490 feet, Glen Canyon Dam cannot generate power. Experts suggest that continuous water output through the pipes is not suggested and instead the water should seek alternate routes. The problem is those alternate routes would no longer be available under 3,490 feet.
In the short term, Lake Powell is not expected to drop beneath its current level through February 2026. But time is of the essence to assure that the dam can deliver transfers of water downstream to the dry Lake Mead.
Damn, dam.
