Lake Fitri is located in the center of Chad. It is fed by seasonal rainfall, so its area can triple in wet years. In extreme drought years, the lake may dry out completely. Wadi Batha empties into the lake from the east, and has created a large delta. Inundated linear sand dunes are found in the western and southwestern part of the image. The image was acquired May 19, 2017, covers an area of 48.9 by 48.9 km, and is located at 12.7 degrees north, 17.5 degrees east. https://photojournal.jpl.nasa.gov/catalog/PIA24018
