The Toshka Lakes, endorheic bodies of water in southern Egypt filled by overflow from nearby Lake Nasser, reached their lowest levels in the 2010's. Heavy rainfall and flooding upstream saw the revival of the lakes in the 2020's. This satellite imagery from JPSS observes the shrinking and growth of the lakes over the last fourteen years. Details: This animation contains the day land cloud product from the JPSS weather satellites. It spans the fourteen-year period from 11:05 UTC on 2012-04-08 to 11:14 UTC on 2026-04-08.
