Three photographs shared on social media present a troubling pattern in Lake Mead over the previous 40 years.
After years of drought, Lake Mead, positioned in Nevada and Arizona, reached considerably decrease ranges final summer season, however water ranges have since begun to recuperate on account of above-average rainfall and snowmelt all through the summer season. Nonetheless, three photographs shared on X, previously Twitter, on Saturday afternoon present that Lake Mead nonetheless has a protracted technique to go in restoration.
Earlier than and after | Hoover Dam 1983-2023: Up to date pictures present water stage rise for annually (2023 ongoing) As of as we speak, Lake Mead is at its highest annual stage at 1,066.29 ft above sea stage – about 34% and 162 ft beneath sea stage The ocean is a whole pool,” X Mojo Adventures account to publish Subsequent to the photographs.
The primary picture exhibits Lake Mead at 1,225 ft in 1983, only a few ft wanting the reservoir’s full 1,229 ft. The second picture of the identical location is 20 years later and exhibits Lake Mead at 1,154 ft in 2003. The third picture reveals that the reservoir dropped one other 88 ft to 1,066 ft over the following 20 years.

Regardless of the startling pattern, Lake Mead’s situation is far improved in comparison with 2022. The lake has gained almost 23 ft since this time final yr, when ranges have been at 1,043 ft. On the time, specialists have been involved that the reservoir would attain a useless pool before anticipated. Lifeless pond happens when water ranges are so low that they will not circulate downstream. If the lake reaches a useless pond, the agricultural results shall be felt by hundreds of thousands of individuals. The hydroelectric energy supplied by Hoover Dam would even be negatively affected by the useless pool occurring at an elevation of 895 ft.
Lake Mead’s enchancment over the previous yr has sparked an optimistic outlook. Nonetheless, specialists stated Newsweek A full restoration is unlikely given drought tendencies and the quantity of water used from the Colorado River, which feeds the reservoir.
Jennifer Pitt, director of the Nationwide Audubon Society’s Colorado River Program, beforehand stated: Newsweek Full restoration can solely be achieved if a three-year common snowfall happens with out water from the reservoir getting used.
Final yr, there was above-average snowfall within the space, which means snowmelt from close by mountain ranges supplemented the lake all through the spring and aided its restoration. Nonetheless, extra enchancment is required.
Water discount efforts are underway, and states within the decrease Colorado River basins, corresponding to Nevada and Arizona, are seeing obligatory water shutoffs. Earlier this yr, Nevada, Arizona and California agreed to chop off a further 3 million acre-feet of water in trade for a fee from the federal authorities.
Regardless of the efforts, UC Davis Professor Jay Lund beforehand stated Newsweek That people ought to scale back their use of water, even when it means fallowing agricultural fields.
“We could also be fortunate with the climate, however the thought of the system recovering may be very troublesome except water use on this basin is diminished,” Lund stated.
