Sawa lake

Sawa Lake is an Endorheic basin located in the Iraqi governorate of Muthanna near to the Euphrates River, some 23 kilometres to the west of Al-Samawa city. This lake has no inlet or outlet, but it draws water from the Euphrates through a system of joint cracks and fissures which transport water to aquifers beneath it. The water's level fluctuates during dry and wet seasons but does not dry up because of the equilibrium state between water feed and evaporation. ()
