English: Recent torrential rains have replenished the water levels of this aquatic gem once known as “the turquoise solitaire of Azerbaijan.” At its greatest extent, Lake Urmia once covered a surface area of 5,000 square kilometers (2,000 square miles).

The image above shows Lake Urmia (also Orumiyeh or Orumieh) on April 12, 2019. The image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Officials report that the lake’s surface area reached roughly 3,000 square kilometers (1,200 square miles) in April 2019—expanding its volume nearly two-fold from a year ago.

The fresh pulse of water came from intense rains during the fall of 2018 and spring 2019. In late March and early April 2019, 26 of Iran’s 31 provinces were affected by deadly flooding from the rain and the seasonal melting of snow cover in the mountains.
