Flagstaff, Arizona — US Government Wednesday, More troublesome prospects for the river It serves 40 million people in the western United States.

The Pioneer Bureau recently First shortage on the Colorado RiverThis means that Arizona, Nevada and Mexico will have less water than usual next year. By 2025, Lake Mead, a barometer of the amount of river water acquired by some states, is 66% likely to reach California’s second stage of reduction. The most populous states in the country have the highest rights to river water.

Reservoirs on the Nevada-Arizona border are important for the three states in the lower Colorado River basin, Lake Powell At the Arizona-Utah border, there are guides to the upper reaches of Colorado, New Mexico, Wyoming, and Utah. A small reservoir upstream of Lake Powell discharges water into a huge lake so that hydropower can continue. However, according to the Pioneer Department, the bumps from the release launched this summer are not taken into account in the five-year forecast.

According to agency projections, Lake Powell is 90% likely to reach a level where the Glen Canyon Dam, which prevents it, will not be able to generate electricity in July 2022 if there is another dry winter in the area.

“The latest outlook for Lake Powell is awkward,” Wayne Powell, director of the upstream region, said in a statement. “This highlights the importance of continuing to work with basin states, tribes and other partners to resolve the issue.”

Lake Powell and Lake Mead, the largest artificial reservoirs in the United States, rely primarily on snowmelt.They have been hit hard Sustained drought In climate change characterized by warming and arid trends over the last 30 years.

Both have fallen to historical lows. According to the Pioneer Department, the total capacity of the lake on Wednesday fell from 49% last year to 39%.

Seven states that depend on the Colorado River approved a drought program in 2019 to support the lake by voluntarily providing water. Everyone agrees that more needs to be done, and when both expire in 2026, they are discussing a set of river guidelines and what to replace the overlapping drought plan.

The federal government has also formed a working group.

The Pioneer Department’s five-year forecast aims to help water managers plan for the future with the best available data. The August forecast will determine the water supply to the state.

The agency states that Lake Mead is 22% likely to fall to an altitude of 1,000 feet above sea level in 2025. Federal officials have stated that an 895-foot-downstream state, often referred to as the “deadpool,” will lose access to water.

The agency that supplies most people in Nevada has built “straws” to draw water from below Lake Mead as the water level drops.
