Lake Powell Water Level Hits Historic Record Low
Tap title to read story
Lake Powell's water surface level has dropped to a historic low of 3,517.24 feet, falling beneath the previous record mark set in April 2023. Newly released satellite data from the NASA-USGS Landsat 8 Operational Land Imager confirms the ongoing contraction of the major Western reservoir amid compounded regional drought conditions. The updated hydrologic metrics provide precise comparative evidence of the shrinking shoreline near Glen Canyon Dam. The Bureau of Reclamation and associated monitoring entities track the reservoir level changes as the water footprint continues to recede from previous multi-year markers.
