Flagstaff, Arizona. – The US government released a forecast on Wednesday showing a more awkward outlook for rivers servicing 40 million people in the western United States.
The Pioneer Department recently declared the first shortage on the Colorado River. This means that Arizona, Nevada and Mexico will get 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.
Reservoir on the border between Nevada and Arizona is important for the three states in the lower Colorado River, while Lake Powell on the border between Arizona and Utah is in Colorado, New Mexico, Wyoming, and Utah. It is a guide for the upstream area. 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 by persistent droughts in climate change, characterized by warming and dry trends over the last three decades.
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.
Authorities say there is a 22% chance that Lake Mead will fall to an altitude of 1,000 feet (304 meters) above sea level in 2025. Federal officials say downstream states will lose access to water at 895 feet (272 meters). It is called “deadpool”.
The agency that supplies most people in Nevada has built “straws” to draw water from below Lake Mead as the water level drops.
