CAPTION: Recently replenished saltwater Lake Urmia (northwest Iran) is seen in this 12 April 2019 image. Once covering a surface area of 5000 km2, drought and high demand for water beginning in the 1970s diminished its size by 80%. Then, after heavy rainfall in fall 2018 and spring 2019 and seasonal snowmelt runoff, the lake surged to roughly 3000 km2 in April 2019.
