1 inch = 2 billion gallons. Over seven days (Aug. 20-27), the lake gained about 13 and a half inches – 27 billion gallons. The increase at Lake Mead is because releases from Glen Canyon Dam – 280 miles upstream on the river – have increased.

The increase at Lake Mead is because releases from Glen Canyon Dam — 280 miles upstream on the river — have been increased. While Hoover Dam is releasing water at 7,712 cubic feet per second (cfs) over the past week, it has been getting water released from Glen Canyon Dam (Lake Powell) at 12,635 cfs.
One year later, Mead's elevation is inching back up. A combination of historic winter snowpack and new federal agreements to pay cities, farmers and tribes to conserve water are expected to raise Mead to a high point of 1,070 feet in February 2024, according to the most recent federal data.
What happens if Lake Mead dries up forever? If Lake Mead were to run out of water, the Hoover Dam would no longer be able to generate power or provide water to surrounding cities and farms. The Colorado River would essentially stop flowing, and the Southwest would be in a major water crisis.
Electricity would not just be the only thing lost. Without Lake Mead, Las Vegas would lose access to 90 percent of its water sources. If Lake Mead were to reach dead pool, it would technically still be able to supply drinking water to Las Vegas. But there will not be enough water for agricultural activities.
But that heavy rainfall likely had little effect on Lake Mead's water levels. The reservoir sat at about 1,063.4 feet in elevation when the rains started on Friday. By Monday night, it had ticked up to 1,063.8.
Lake Powell and Lake Mead are unlikely to refill for another 50 years - and would need SIX consecutive years of deadly atmospheric rivers to replenish.
The Lake Mead problem could be resolved by draining Lake Powell and storing the water in Lake Mead. More than 5% of the water in the Colorado River evaporates off the surface of Lake Powell - which never should have been built.
Record snowfall in the West wasn't enough to alleviate drought impacting Lake Mead. The record snowfall in the West wasn't enough to permanently alter the course of the drought impacting Lake Mead. FOX Weather's Robert Ray reports on the ongoing water issues and the Colorado River.
Lake Powell and Lake Mead - the nation's largest reservoirs - are unlikely to refill for another 50 years and would need six consecutive years of deadly atmospheric rivers to replenish, experts say.
As crazy as it sounds, engineers say the idea is technically feasible. It would involve building a system of dams and pipelines to move the water uphill across multiple states over the Continental Divide. Gravity would then work in our favor to drop the water down to the Colorado River watershed.
Investments to enhance system conservation and improved hydrology have led to significant improvements for Lake Mead this year, the federal government announced Tuesday, after the lake hit historic lows last year and the remains of several bodies were found.
Mead reaches dead pool at 895 feet. If Lake Powell reaches dead pool, the US Bureau of Reclamation—which declined our interview requests—would be unable to meet its obligation to deliver water downstream to Lake Mead. In which case, 40 million people would be affected.
Powell's physical elevation is projected to be 3,574.30 feet on December 31, 2023. With intervening flows between Lake Powell and Lake Mead of 1.32 maf in CY 2023, Lake Mead's physical elevation is projected to be 1,065.42 feet on December 31, 2023.
As much as we clearly wanted it to, Hurricane Hilary couldn't help with that. Its rain didn't reach into the Rockies to sate those soils. And while Hilary drenched areas near Lake Mead, it gained less than a foot of elevation in the days after the storm (it is a big lake, after all, which takes a lot of water to fill).
Rain runoff into the tributaries that eventually feed into Lake Mead contributed about 112,000 acre-feet more water than what the bureau projected, which accounted for about 1.6 feet of the reservoir's rise, Helms said.
LAS VEGAS (KLAS) — Television and social media videos of raging floodwaters after Tropical Storm Hilary lead the public to ask, “Does all that water help?” The answer is complicated, but officials say Hilary's direct effect on Lake Mead was “minor” and had more to do with reduced demand than anything else.
If the water levels dip much lower, the Colorado's northernmost reservoir won't have enough in the tank to both fill Lake Mead downstream and generate any hydropower, which would have devastating effects on the electricity grid in the western US.
The water elevation in Lake Mead is around 1,040 feet above sea level. At 950 feet, Hoover Dam will be at its lowest point to be able produce power, according to the US Bureau of Reclamation.
The vast reservoir's water level has dropped more than 170ft (52m) since 1983, the same year the Colorado River flooded the dam's spillways. Over-extraction, extreme heat and decreased snowmelt have burdened the Colorado River Basin and nearly 40 years later, Lake Mead is down to about 27% of its capacity.
