Will snow melt raise Lake Mead?

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. That elevation will likely change as more conservation agreements are signed.

“While the amount of precipitation received from the recent storms in the lower basin and from tributary inflows helps, the greatest source of water for Lake Mead is still from snow melt and flows from the upper basin — especially from good winter snowpack from the west slope of the Rocky Mountains,” Hendrix said.

The water levels for Lake Mead are projected to reach slightly over 1,065 feet by January 2024, according to the Bureau of Reclamation, in large part due to an extremely wet winter that eased the effects of the longstanding drought. In October 2022, the water levels were at a historic low, at roughly 1,046 feet.

How long does Lake Mead have left? Lake Mead has been facing a water crisis for many years. The water level in the lake has been dropping due to the increasing demand for water and the decreasing supply. If the trend continues, the lake could run out of water in the next 10 to 15 years.

“Although every drop counts, the reality is that the rain we received from Tropical Storm Hilary and runoff into the tributaries that enter Lake Mead as well as reduced releases from Hoover Dam — due to a decrease in downstream demand — has had some minor impact on the lake's elevation,” according to U.S. Bureau of ...

Lake Mead water levels up after snowy winter, former Hurricane Hilary. Lake Mead water levels were at record low levels last summer but snow over the winter and former Hurricane Hilary helped restore some water to the basin.

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.

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.

Rising temperatures due to climate change have sapped more than 10 trillion gallons of water from the Colorado River over the last two decades, enough water to completely fill Lake Mead from top to bottom, according to a recent study from researchers at UCLA.

Since 1983, years of drought along with high water demand have caused the lake to drop by 132 feet. Today, the lake is at only 30% capacity, its lowest level since it was built in the 1930s. Fortunately, heavy rainfall early in 2023 has relieved the situation a little, but only temporarily.

Most of our rainwater travels untreated through gutters, storm drains, channels, washes and eventually into the major source of our drinking water - Lake Mead. All storm drains lead to lake mead. Stormwater that falls in the Las Vegas Valley picks up pollutants and travels untreated to Lake Mead.

The amount of water that melted off and made its way into the river system was enough for the Bureau of Reclamation to release far more water from Glen Canyon Dam at Lake Powell this year, which means more water flowing downstream into Lake Mead.

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.

The Bureau of Reclamation's most recent projections show Lake Mead dropping to 1,033.4 feet in elevation by the end of 2023, about 14 feet lower than the reservoir's current level. That projection is about 12 feet higher than the 2023 end-of-year mark in the bureau's forecast from December.

This could be catastrophic for the southwestern U.S as we know it, as the Hoover Dam, which forms the lake, is also integral to irrigating water throughout the region. Lake Mead's water is not just used for consumption, but for agriculture, and hydropower. If water runs out, the Hoover Dam could stop functioning.

Lake Mead's water level continues to fall to historic lows, bringing the reservoir less than 150 feet away from “dead pool” — so low that water cannot flow downstream from the dam. The loss of water entirely from this source would be catastrophic.

The last time Lake Mead was at maximum capacity, reaching an elevation of about 1,220 feet near the dam, was in 1983 and 1999, NASA notes.
