DENVER (AP) — The outlook for the most important river in the Southwestern U.S. remains grim this summer after April storms failed to produce much snow in the mountains that feed the waterway, forecasters said Monday.

The National Oceanic and Atmospheric Administration said the Colorado River is expected to carry only 43 percent of the average amount of water into Lake Powell, one of two huge reservoirs that store and distribute the river.

It’s the fifth-lowest forecast in 54 years.

“It’s pretty dramatic. It’s a very low runoff season,” said Greg Smith, a hydrologist with the agency.

But officials have said that Lake Powell and its companion, Lake Mead, will be high enough to avoid mandatory cutbacks for water users this year.

The Colorado River serves about 40 million people and 6,300 square miles (16,300 square kilometers) of farmland in United States and Mexico.

Arizona, California, Colorado, Nevada, New Mexico, Wyoming and Utah all use the river or its tributaries, along with 20 native American reservations.

The river is under increasing stress because of rising demand and declining flows. The region has been in a drought for 18 years — long enough that some researchers say it may represent a permanent shift.

Global warming is also contributing to the reduced river flows, scientists said.

Last year’s snowfall was uneven but mostly below average across the mountains that feed the Colorado.

  1. Seems to me instead of spending billions on foreign aid, the US might built vast pipelines to shuttle snow melt from Alaska to the SW. This could be financed by selling off USG owned properties in the West to US citizens in lots not exceeding 2,000 acres. In addition I’d build nuclear reactors which require cooling to be built in Alaska to facilitate both energy production and to help melt snow to provide year round power and water supply. Everyone wins, jobs, infrastructure, energy independence and an improved energy grid.

    Water supplied should be at a charge per 100,000 gallons to be based on maintenance costs of the pipeline and associated infrastructure.
