LAS VEGAS (AP) - Authorities say levels at Lake Mead are expected to drop this year because of drought conditions.
KLAS-TV reports the western slope of the Rocky Mountains would need at least seven years of normal snowfall to bring southern Nevada out of its 12-year drought.
A Southern Nevada Water Authority spokesman says he expects the Colorado River will end up at just 46 percent of its average flow.
Most of Las Vegas' drinking water comes from Lake Mead. It rose 30 feet last year because of record snow pack in the West. Officials couldn't say how far lake levels would drop this year.
