From The Boulder City Review (Celia Shortt Goodyear):
The water at Lake Mead is projected to be at its highest level in years, but the drought is still not over, according to the Bureau of Reclamation.
Lake Mead’s elevation is around 1,092 feet, which is the highest it has been since May 2014, but it is still only 42% full, said Patti Aaron, public affairs officer for the bureau’s Lower Colorado Basin Region.
“Drought isn’t determined by the amount of water in Lake Mead,” Aaron said. “We would need to see at least two to three back-to-back years of above-average hydrology, hopefully more, to say we are out of the drought. There isn’t a set definition of when drought ends.”
There have not been two back-to-back good years since the late 1990s.
Aaron said the higher water levels are due to a wet November and December, causing an above-average inflow into the lake.
“Regarding the rising lake levels, this is part of the normal seasonal trend in which cooler weather reduces water orders from Lake Mead,” she said.
She added that the water level will decline by nearly 20 feet in the spring and summer because water orders will increase before the elevation rebounds later in the year.
The higher water levels are also due to conservation by the lower basin states and Mexico. The Lower Basin Drought Contingency Plan, which took effect on Jan. 1, requires water savings contributions by the United States and Mexico.
Aaron said voluntary conservation activities added about 9 feet to Lake Mead’s elevation last year.
