As the drought has gone on for so long, despite the rain giving respite to Lake Mead's water levels, it will take a lot more wet weather to fix the problem. Lake Mead doesn't just rely on rainfall for its water, but snowpack that flows down through the mountains. The ongoing drought in the western United States has been one of the driest stretches seen in the U.S. in the past 1,200 years. The lake's water levels have risen slightly. The park is actively evaluating the long-term implications of ongoing historic drought on recreational infrastructure and analyzing the most accurate scientific data available to make the best decisions possible. The lake is now at 28 percent its usual capacity, while during the summer it was only at 27 percent. A Tier 3 shortage would impact the amount of . Let us know via science@newsweek.com. The reservoirwhich stretches across Nevada and Arizona, on the Colorado Riveris relied upon by 25 million people living in the region. "We also have two important decisions coming up. One of the towns final residents left in 1938 when waters reached his front door, according to the Deseret News. The Lake hadn't reached such a low level since it was constructed in the 1930s. Importantly, the Bureau of Reclamations studies are based on historical data from the 1990s a much wetter period in the West, said Eric Kuhn, a retired former manager of the Colorado River Water Conservation District. Updated The region is already in an unprecedented Tier 1 shortage on the Colorado River, which led to mandatory water cuts that mainly impacted agriculture. The May forecast also includes about half of the water needed to carry out the 500-plus plan, which was supposed to keep Lake Mead just above its last major defense point of 1,020 feet if we voluntarily saved 500,000 acre-feet of water, over and above whatever mandatory cuts we must make based on the level of shortage the lake has reached, each year for five years. A side by side comparison shows the changes in Lake Mead's water levels since 2000 to 2022. And Lake Mead today, Jan. 31 2023. Lake Mead's water levels, despite having increased in the wake of massive rainfall across the western states, are still much lower than they were this time last year. 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 . Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion. Notably, exceptional drought the worst designation expanded in California from nearly zero coverage to 11% of the state. At 1,050 feet, a Tier 2 shortage is declared, further decreasing the amount of water Arizona, Nevada and Mexico can use from the Colorado River. All rights reserved. However, as of January 11, Lake Mead was still only at 28 percent of its full pool level. The U.S. Drought Monitor has changed Nevada's status 0 percent in an exceptional drought, due to the rainfall. The monthly, two-year forecast from the U.S. Bureau of Reclamation has once again been revised down, with lake levels hitting a new potential low of 1,007 feet of elevation in November 2023.. Order your guide, either as an ePub ebook for your Kindle or as a PDF version. Recent rainfall and an increase in the snowpack on the Colorado Rocky mountains has made more water available for reservoirs like Lake Mead and its neighbor Lake Powell. A forecast from the Bureau of Reclamation released on August 31 show the two and five year projections at the lake. - Hundreds of firefighters scrambled Monday to prevent a wildfire engulfing an area of rare giant sequoia trees in California's Yosemite National Park. Its been sad to watch the lake drop, the islands appear, the bathtub ring, the marina being moved out further and further.. ), they also limit the amount of groundwater that is stored within the landscape," Daniella Rempe, a hydrologist and geomorphologist at the Jackson School of Geosciences, University of Texas in Austin, previously told Newsweek. Which lets just call it now is highly unlikely. Water levels in Lake Mead reached the lowest they have ever been last July, at 1,040.8 feet. Reach Allhands at joanna.allhands@arizonarepublic.com. Lake Mead is the largest reservoir in the U.S., formed by the Hoover Dam on the Colorado River. #ColoradoRiver #drought pic.twitter.com/g2F9lCXbfw. Water level status projections from the BOR's March 2022 Most Probable Inflow 24-Month Study: The current water elevation for end of March is 1,063.11 feet. Results from CRMMS run with ESP are referred to as CRMMS-ESP. But even though the water levels have risen, this isn't likely to help the lake in the long term. As of December 1, the water levels stood at 1,042.97 feet. In the worst-case-scenario, the. Firefighters put out hot spots from the Washburn Fire in Yosemite National Park, California, July 11, 2022. From there, the Bureau projected the water levels could keep declining, before reaching the low point of 1,024.47. Boaters are being advised to check the status of their preferred launch destination(s) on theparks websiteand consider planning their trips to avoid high-traffic times. Our commitment to understanding the impacts of climate change on park resources, infrastructure, operations, and visitor experiences is central to ensuring the safe, responsible and long-term use and enjoyment of all Lake Mead has to offer. The state saw a particularly wet monsoon season at the end of July and into August, meaning the river filled slightly. You will find things in the lake. The full Colorado River system supplies water to 40 million people in seven western states as well as Mexico, and irrigates more than 5 million acres of farmland from Wyoming to the Gulf of California. In August, Reclamation will make two model runs: One that, as the May 24-month study does, projects lake levels as they are, and one that projects lake levels as if that extra water were in Mead. This means less water will be portioned out to some states in the 2022 water year. But the recent projections show it will take a lot more than rainfall to change the dire outlook for the lake. After three months of rising levels, Lake Mead is then projected to drop for seven consecutive months, when it will be at 1,023.71 feet. CNN The water level in Lake Mead the nation's largest reservoir dropped below 1,050 feet elevation for the first time last week, a critical milestone that signals more stringent. While July is typically a dry time of year in the region, 2022 was a particularly low point for Lake Mead. But even that rosier prediction is8 feet lower than last month, thanks in part to another meh runoff season and recent, unprecedented actions that were taken to keep the upstream Lake Powell on life support. The current water elevation for end of March is 1,063.11 feet. Lake Mead is currently operating under a federally declared water shortage and its allocation of water for 2022 has been cut by 21,000 acre feet to 279,000 acre feet . If water levels keep declining, it could mean bad things for surrounding cities and communities that rely on Lake Mead for water. The combination of dry soils, a third La Nina and critically low reservoirs levels is a major concern.. By January 18, Lake Mead's water levels have risen to 1,045.76 feet. The lake's water levels have risen since December, but are forecast to reach an all-time low later in the year. A grueling drought in the American west has depleted the lake, a crucial water source for 25 million people, drying out tributaries, threatening hydropower production and closing boat ramps at the popular recreation site. Hot records are outpacing cool by more than 10-to-1 this year as Europe, US brace for dangerous heat. Projection for end of April 2022 is 1,057.14 feet. Water levels at Lake Mead are projected to drop earlier than expected this summer, based on forecasting from the Bureau of Reclamation. Previous Bureau of Recreation (BOR) projections anticipated this lake level drop happening in May, but the most recent projections suggest it will occur sooner. The sudden rainfall which has swept the region has even changed Nevada's drought status, which usually remains pretty static. It would take several years of much-above average snowpack (unlikely given the warming temperatures), combined with drastically less water usage to let Lake Mead begin to fill again.". The Las Vegas region cut per-person use by 47% between 2002 and 2020, to about 112 gallons, while its population grew by 52%. A Warner Bros. It puts Mead a few inches above the trigger elevation of 1,045 feet in August, when the . Sun 31 Jul 2022 05.00 EDT Last modified on Sun 31 . The disruption in society will beunprecedented. Dr. Joellen Russell, a climate scientist and professor at the University of Arizona and member of the group Science Moms, told Newsweek: "Lake Mead is more than 180 feet below its "full level" and hasn't been close to full since 1999. REGISTRATION DOES NOT IMPLY ENDORSEMENT, APPROVAL, OR RECOMMENDATION BY THE STATE. Lake Mead is a not natural body of water, Green points out. The new projections also estimate that the level will drop again to 1,040.83 feet in March 2023. Inside were the remains of a man who officials say was shot between the mid-1970s and the early 1980s. Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion. Exploring the National Park System by RV is one of the quintessential approaches to visiting national parks, monuments, national recreation areas, and other park system units that combined represent what Wallace Stegner defined as the best idea America ever had. Projection for end of April 2022 is 1,057.14 feet. The latest forecast would suggest that California, Arizona, Nevada and Mexico would see even more significant cuts to their Colorado River water starting in January, and without a couple of blockbuster winters with lots of rain and snow more severe cuts the following year that would stretch into household and industrial use. The lingering drought is the overriding reason that the lake's water level will fall again in 2022, but it's . Managing for both short-term emergencies and long-term sustainability makes this situation particularly difficult.". Callville Bay launch ramp is open on one lane of pipe mat and will likely close in April 2022 or when the lake level drops below 1,062 feet elevation. But the Lake's water levels have risen slightly recently, from 1,044 feet at the end of 2022, to 1,045 feet at the beginning of 2023. The legal framework is really complicated, but it's urgent to change it right now before the risk increases and there's no water for everyone and everything dependent on water from Lake Meadfarms, birds, major cities, really all life in the Southwest.". Reclamation only includes about half because thats all the agreements that have been signed. The reservoir relies on rainfall and winter snowpack to replenish its water levels. This is due to recent heavy rainfall and winter storms that swept across Nevada and the neighboring states. Good question. Meaning that once the buffer on Mead is gone, its gone. There is some opportunity for the Colorado River to pick up more inflow between Lake Powell and Lake Mead, from springs and small creeks in the Grand Canyon but drought and climate change have been reducing these flows, as well. "Today the water uses allowed by law are more than the river gets in an average year, so until the rules are changed it is unlikely the reservoirs will fill.". It is formed by the Hoover Dam, which was first constructed between 1931 and 1936. 2. "It has gotten warmer and drier, and the rules haven't changed fast enough to stop the decline.

South Coves launch ramp is closed, but primitive launching is still available approximately 0.5 mile to the south of the concrete launch ramp. The reduction of releases from Lake Powell from 7.48 maf to 7.00 maf in WY 2022 resulted in a reduced release volume of 0.480 maf that normally would have been released from Glen Canyon Dam to Lake Mead as part of the 7.48 maf annual release volume, consistent with routine operations under the 2007 Interim Guidelines. The 5-Year Probabilistic Projections are generated using the Colorado River Mid-term Modeling System (CRMMS) in Ensemble Mode. If the forecast indicates Lake Meads water level will be below 1,050 feet come January 1, the Southwest will move into the second tier of unprecedented water cuts that will deepen the impacts for cities, industry and tribal water users. The colored region, or cloud, for the scenario represents the minimum and maximum of the projected reservoir elevations. They are typically updated every January, April, and August, while probabilistic results for the 2-year period are updated every month. Highest congestion at launch ramps typically occurs on weekends, so weekday visits are encouraged when possible to enjoy the lake with fewer crowds. Launch ramps at Temple Bar and Boulder Harbor will remain closed. . Its a point we want to avoid (that is, if we can). 2. Lake Meads plummeting water level has become more apparent over the past year. The Lake hadn't reached such a low level since it was constructed in the 1930s. More human remains were discovered at Lake Mead, California is in a water crisis, yet usage is way up. Experts believe only a change in water policy can contribute to saving the lake. Lake Mead's water levels could reach an all-time low in 2023, projections from the Bureau of Reclamation show. Koebele said there are policies being put in place such as the Drought Contingency Plan. Elizabeth Koebele, an associate professor of political science at the University of Nevada, Reno, told Newsweek: "This is a Colorado River problem what I call a "system problem" and we'd be remiss to think of it otherwise. How much variance will that be? Did you encounter any technical issues? The Colorado River reservoirwhich has been rapidly drying up due to the ongoing megadrought gripping Nevada and neighboring statescould reach lows of 1,024.47 feet by November, a study released by the Bureau on January 19 said. However, the section containing Lake Mead is still within the "severe drought" category. Water levels in Lake Mead reached the lowest they have ever been last July, at 1,040.8 feet. At Tier 3 something the forecast suggests is possible starting in January 2024 water cuts could be deep enough to extend beyond agriculture and impact household and industrial water use.

Whatever buffer we may have had (or thought we had) at Lake Mead, it is quickly disappearing. While Lake Mead National Recreation Area in Nevada is open for business, declining water levels could create problems for those hoping to launch power boats this year, according to the National Park Service. Since the beginning of December, the reservoir's water levels have steadily increased. Although these are only estimates, the lake has been in a dire state for years, meaning it is likely that water levels will drop further than they already have in the coming year.
