Lake Dumat al-Jandal is an anthropogenic body of water, created in Dumat al-Jandal, Al-Jawf Province, northern Saudi Arabia, as a means of mitigating the risk of flooding caused by excess irrigation water from palm plantations.
To accommodate the excess water, surface wells were constructed to facilitate its elevation and subsequent discharge over a neighboring hill, thereby forming the basis of this artificial lake.
The lake was formed due to the irrigation project that commenced in 1987, with the water flowing from the surrounding hills into the depression in the ground.
[3][4] The development of Lake Dumat Al-Jandal commenced in 2006, following the construction of the surrounding streets, which were paved and illuminated.
Its storage capacity is approximately 11 million cubic meters of water annually, with an equal amount evaporating.
