Trend of "Aridification" of Southwest Continues

Steadily Diminishing Annual Snowpack

After dry winter, Colorado River forecasters look for 6th-driest runoff year,
AZ Central, April 4, 2018.

"...sixth-driest runoff season into Lake Powell since the government erected Glen Canyon Dam there 55 years ago."

"...a projected April-July runoff season supplying just 43 percent of what Lake Powell receives in an average year."

"The worst year on record was 2002, when the reservoir collected less than 1 million acre-feet."

"The U.S. Bureau of Reclamation currently projects that Lake Mead, filled by releases from Lake Powell, will stay high enough to avoid mandated cutbacks next year but could be on the verge of shortage levels by 2020."
