Lessons being learned from Glen Canyon Dam

But it is not just the reservoir’s overuse that is causing it to shrink. More than 160 billion gallons of water evaporate off Lake Powell’s surface every year, enough to lower the reservoir by four inches each month. Another 120 billion gallons are believed to leak out of the bottom of the canyon each year into fissures in the earth — a loss that if tallied up over the life of the dam amounts to more than a year’s flow of the entire Colorado River.

In all, these debits amount to “the largest loss of water on the Colorado River,” Mr. Beard said, enough to supply some nine million people each year.
