Environmentalists warn that the Grand Canyon could dry up without dam repairs

A coalition of environmental teams warned Wednesday that the federal authorities should shortly put together plans to revamp the water pipes on the Glen Canyon Dam to maintain the Colorado River flowing by means of the Grand Canyon as water ranges behind the dam proceed to drop.

Lake Powell is barely 1 / 4 full, its floor is now 3,536 ft above sea stage—46 ft under the extent for hydroelectric manufacturing—and plummets after early summer season snow rushes from the Rocky Mountains. Two extra dry winters may push the reservoir past that time, in response to forecasters, and ultimately dam managers might must open bypass tunnels simply over 100 ft deep to maintain the river flowing.

If it involves that, river advocates and their new warning warn, these tunnels will show inadequate to launch as a lot of the water that the Southwest is determined by to go by means of the Grand Canyon and restock Lake Mead annually.

“This method wants resilience and it wants it now,” stated Eric Balkin, whose Glen Canyon Institute has partnered with the Utah Rivers Board and Nice Basin Water System in a brand new report urging motion.

Ground buoys are ashore in Wahweap Bay on February 3, 2022, near Page.  Lake Powell was at 26% of its capacity, 168 feet below its full height of 3,700 feet above sea level at the time.

Lake Powell’s elevation has decreased greater than 160 ft because it was primarily full on the flip of this century, and its tempo has accelerated in recent times. Rolling again what the retailers are designed to deal with will jeopardize the supply of water wanted to irrigate farms and provide cities completely from Phoenix and Las Vegas to Los Angeles and Tijuana.

The teams’ quest is to steer the US Bureau of Reclamation, which manages the dam, to review find out how to preserve the river’s circulation, their evaluation suggests, if local weather change and overuse of the system push the system to its breaking level within the coming years. Their most well-liked alternate options are to both broaden the capability of the bypass tunnels or construct new tunnels on the base of the dam to permit the river to circulation even when Lake Powell empties.

Company on the lookout for methods to take care of power manufacturing

Of their first speculation – the necessity to act to forestall hydroelectric loss – they’ll discover settlement from many angles. The Bureau of Reclamation, the state of Arizona and the group representing hydroelectric clients for the dam say twenty years of drought within the space pose an imminent risk to regular operations in Glen Canyon.

“Given the present uncertainties dealing with the Colorado River system, in addition to the engineering uncertainties concerned in shifting water by means of the present Glen Canyon Dam infrastructure at traditionally low ranges, it could be prudent to completely examine all cheap choices for making infrastructure adjustments. A dam that enhances its means to soundly transport massive quantities of water,” stated Arizona Water Assets Director Tom Buchatzky.
