Lake Mead, the largest reservoir in the United States, has hit its lowest water level since it was first filled nearly 90 years ago. This decline underscores the ongoing crisis affecting the Colorado River system. Federal data showed that water levels at Lake Mead dropped to 1,040.4 feet (317.1 meters) above sea level last Friday. This measurement slightly fell below the 1,040.58 feet (317.27 meters) recorded on July 28, 2022. The reservoir is located at the Arizona-Nevada border near Las Vegas.
The record comes after a winter that yielded the worst snowpack on record in the Colorado River Basin. Snowmelt contributes to the river, serving as a crucial resource for farmers, industries, wildlife, and over 40 million people across seven U.S. states, tribal nations, and Mexico. Recently, federal officials put forward a short-term plan to prevent further crisis in the waterway. This intervention came after states dependent on the river — California, Colorado, Arizona, Nevada, New Mexico, Wyoming, and Utah — failed to reach a long-term sharing agreement. Under the proposal, water cuts would be shared among California, Nevada, and Arizona.
Years of overuse, drought, and rising temperatures have significantly diminished both Lake Mead and Lake Powell, the second-largest reservoir in the country. Presently, they are at their lowest levels in nearly seventy years. To safeguard the hydropower capabilities of the strained system, federal officials announced on Thursday that they would not release cool water from Lake Powell’s Glen Canyon Dam in northern Arizona. The decision aims to protect a threatened native fish species whose habitat lies between the two reservoirs.
Drought conditions in 2022 exposed human remains and forced officials in Las Vegas to utilize deeper reservoir sources to ensure a continued water supply for millions.
