Colorado River will reach record lows after worst ever Rockies snowpacks

According to a federal forecast issued on Thursday, Colorado River flows will reach record lows in Lake Powell this summer after the lowest ever snowpacks were recorded in Colorado, Utah, and Wyoming.

According to the Colorado Basin River Forecast Center, a March heatwave "prematurely" melted any snow that fell during a warm and dry winter. This will result in Colorado River flows to Powell being only 13% above average from April to July.

This would be the lowest spring-summer runoff since 1963, when the reservoir was created. It supplies water to 40 million people in cities like Los Angeles, Phoenix, and Las Vegas.

Cody Moser said, "There's no good news this winter" in a webcast.

Scientists attribute the U.S. Southwest's megadrought to climate change. The scientists have attributed this to rising temperatures in the region, which has caused aridification, and a fall in stream levels.

The seven states in the Colorado River?Basin that rely on the river will be affected by low flows.

The U.S. Bureau of Reclamation began to reduce the amount of water released from Lake Powell in order to prevent it from falling too low to allow hydroelectric production.

The seven states of the river basin have been in talks for a long time to come up with a deal on water sharing this year. If they fail, then the federal government will intervene. It operates Powell Reservoir and other reservoirs along?the river.

Nevada, Arizona, and California - the states in the lower basin - offered on Friday to reduce their water consumption.

Eric Kuhn is a water researcher who expected state and local governments would impose additional outdoor restrictions in order to deal with?any possible water shortages this year.

Kuhn, former Colorado River water manager in the state of Colorado, said: "I do not see anyone who is going to shut off water inside houses or fire hydrants."

Phoenix has called for voluntary conservation measures in order to deal with the likely water shortages. Los Angeles limits outdoor sprinkler watering to three days per week.

A strong El Nino system that is forecast could improve flows in the lower basin, with heavy monsoon rains. This weather phenomenon is a result of warm Pacific water and causes wetter conditions in southern United States. Andrew Hay, New Mexico (reporting; Aurora Ellis, editing)
