LAS VEGAS (KLAS) — Lake Powell has been reported to be sitting at 26% of its full capacity, which is its lowest point since it started filling in 1963, according to NASA.

The lake’s elevation level at full pool is 3,700 feet. On Aug. 23, the lake’s surface elevation was measured at 3,533.13 feet, over 166 feet below the full pool.

The lake reached full pool for the first time in 1980.
