The location pictured below shows the surface area changes of the tank near Bullfrog Marina, roughly 90 km north from Glen Canyon Dam, in between March 2018 and March 2022. Dry conditions and falling water levels are unmistakable in the image caught on 18 March 2022, compared to the 2018 shoreline detailed in the image in yellow.

The drop in water levels comes as hotter temperature levels and falling water levels left a smaller quantity of water streaming through the Colorado River. The peak inflow to Lake Powell occurs in mid-to-late spring, as the winter season snow in the Rocky Mountains melts.
The line chart shows the drastic drop in average water levels in March considering that 2000, when Lake Powell was at around 1120 m elevation. The existing elevation is just a few meters from what is thought about the minimum power swimming pool– the level at which Glen Canyon Dam is able to produce hydroelectric power. If Lake Powell drops much more, it could soon strike a deadpool where water will likely stop working to flow through the dam and onto the close-by Lake Mead.
According to a report compiled by the US Geological Survey in cooperation with the Bureau of Reclamation, Lake Powells storage capacity has actually lost nearly 7% of its possible storage capacity from 1963 to 2018, when the diversion tunnels of Glen Canyon Dam closed and the tank started to fill.
The capability of the tank is stated to be diminishing since of sediments carried by the Colorado and San Juan Rivers. These sediments settle at the bottom of the tank and decrease the total amount of water the reservoir can hold.
Environment change is expected to make droughts more severe in the future. According to the National Oceanic and Atmospheric Administration (NOAA) Spring Outlook for the United States, almost 60% of the continental US is experiencing drought.
These conditions are likely to continue across more than half of the continental United States through a minimum of June, straining water supplies and increasing the danger of wildfires. While these conditions are not new, the firm expects them to possibly intensify in the coming months.
After years of dry spell, water levels in Lake Powell, the second-largest human-made tank in the United States, have actually diminished to its lowest level considering that it was created more than 50 years ago, threatening millions of people who rely on its water supply. The lake offers water to around 40 million individuals, irrigates over 2.2 million hectares of land, and has the capacity to produce more than 4200 megawatts of hydropower electrical energy.
Dry conditions and falling water levels are unmistakable in the image captured on 18 March 2022, compared to the 2018 shoreline laid out in the image in yellow. The line graph shows the extreme drop in typical water levels in March considering that 2000, when Lake Powell was at around 1120 m elevation. If Lake Powell drops even more, it could quickly hit a deadpool where water will likely fail to flow through the dam and onto the nearby Lake Mead.
This Copernicus Sentinel-2 image enables us a larger view of Lake Powell and its diminishing water levels in the middle of the environment crisis. After decades of drought, water levels in Lake Powell, the second-largest human-made reservoir in the United States, have actually shrunk to its lowest level considering that it was produced more than 50 years earlier, threatening countless people who depend on its water system.

After years of drought, water levels in Lake Powell, the second-largest human-made reservoir in the United States, have diminished to their most affordable level given that it was created more than 50 years earlier, threatening countless people who count on its supply of water. Satellite images permit us to take a closer take a look at the diminishing water levels of the lake amidst the climate crisis.
Straddling the border of southeast Utah and northeast Arizona, Lake Powell is a crucial tank in the Colorado River Basin. The Colorado River, which Lake Powell streams through, was dammed at Glen Canyon in the early 1960s. The lake supplies water to roughly 40 million individuals, waters over 2.2 million hectares of land, and has the capacity to produce more than 4200 megawatts of hydropower electrical energy.
In mid-March 2022, Lake Powells elevation dropped to an astonishing 1074 m above water level– the most affordable the lake has been because it was completed 1980. This extreme drop in water levels is recorded in natural-color images caught by the Copernicus Sentinel-2 mission.
