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. Aridification has led to low soil moisture and reduced runoff efficiencymeaning that even if we get big storms, less of it becomes runoff in the river. Please refer to this discussion of uncertainty for more information. The March 2022 forecast estimates are . The latest report from the US Bureau of Reclamation shows Lake Mead at just over 1,040 feet above sea level in July, having dropped nearly 10 feet in just two months, and is currently at just 27% of its maximum capacity. Sunken boat from second world war and at least three sets of human remains found in largest US reservoir and more could follow. "But, remember, because our reservoirsparticularly Powell and Meadare so low from 23-plus years of drought, it would take many years of above-average snow and runoff to refill the reservoirs. Projected water levels are provided typically on the 15th of each month by the BOR. 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. appreciated. Additionally, if too much rain comes at once, or too much snowpack melts at once due to higher temperatures, it risks running off into the ocean rather than refilling aquifers where we need it. A file photo of Lake Mead. Wet years in the 1990s and 2000s did not refill the lakes it simply kept them from going lower. Horizontal gray lines represent important elevations for operations.

There tends to be plenty of stuff that goes to the bottom and you just wait around, Green said. Projection for end of July 2022 is 1,046.87 feet. 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. The region is already in an unprecedented Tier 1 shortage on the Colorado River, which led to mandatory water cuts that mainly impacted agriculture. Jennifer Pitt, the Colorado River program director with the National Audubon Society, an environmental organization, previously told Newsweek: "To refill the Colorado River reservoirs, you would need three average years of snowfall without any water use. California and Nevada have had extremely heavy rainfall in recent days, during one of the severest droughts the region has ever seen. California snowpack provides 30% of the states water, according to the Department of Water Resources. He also cautioned that the Pacific Ocean is heading into its third La Nina year in a row, which is a very rare event. La Nina, defined by cooler-than-average water in the equatorial Pacific, has a strong influence on weather in the US West. 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.

"Two, many of the current policies that govern Colorado River allocations, including the DCP and other shortage-sharing guidelines, expire in 2026, so the states and federal government are simultaneously beginning a process to develop rules for the next 20 years of Colorado River management that can help mitigate some of these issues. Everyone Practices Cancel Culture | Opinion, Deplatforming Free Speech is Dangerous | Opinion. Projections at Lake Mead show there is a chance as high as 66% that water levels will decline to 1,025 feet by 2025, triggering a Tier 3 Shortage. This means less water will be portioned out to some states in the 2022 water year. The reduction of releases from Lake Powell from 7.48 maf to 7.00 maf in water year 2022 will result 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. How much variance will that be? Echo Bay will operate on two lanes of concrete; one lane of pipe mat extension will be installed at 1,060 feet elevation. These reservoirs were built to store water in wet years in order to mitigate occasional drought. The reduction of releases from Glen Canyon Dam in water year 2022 (resulting in increased storage in Lake Powell) will not affect future operating determinations and will be accounted for as if this volume of water had been delivered to Lake Mead. There might actually be some archaeological relics, Green said, adding that a nearby museum has artifacts from the Puebloan people, who lived in the area about a thousand years earlier. "There's been a good start to the snowfall season, but it is way too early to know what runoff will look like," she said. The NPS recognizes the important role that launch ramps and marinas play in the economies of gateway communities and the numerous businesses that operate in the parks, and robust civic and stakeholder engagement will be a part of longer-term planning. The current water elevation for end of March is 1,063.11 feet. Now, keep in mind: That 1,007-foot prediction is in whats called the minimum probable forecast, not the comparably rosiermost probable forecast that Reclamation typically uses to declare shortages and take other official actions. Launch ramp access on Lake Mohave will remain stable. But she also pointed more generally to the Southwests worsening drought, which has increased the amount of water agriculture is pulling from the Colorado River.
