Maybe you’ve heard that Lake Mead is on the rise again. It’s up a little more than it was a year ago, about 20 feet higher than where it was at this time last year. They released more from Lake Powell upstream in April. Plus, we had a very snowy winter. Snowmelt from the western slopes of the Rocky Mountains feeds the Colorado River. But everyone who lives in Las Vegas or Northern Nevada knows that this all just a mirage. One wet winter does not overturn more than 20 years of drought.
