The current Ubari Lakes are a group of about 20 lakes, set amidst the landscape of towering dunes and palm fringed oases of the Ubari Sand Sea. To reach these lakes, tourists usually drive to Sabha, then from Sabha to Tkerkiba, where an excellent camping site is used as the base to explore the lakes as well as Wadi Matkhandouch. The depth of the lakes, according to one Libyan diving centre, varies from seven meters deep (as in Gabroun) to 32 meters deep (Ain al-Dibbanah, near Ghadames). Some of these lakes are slowly drying out, owing to drought and artificial drainage of underground resources! 4 {( ^$ c0 Y6 T8 Jtvb now,tvbnow,bttvb @2 a2 z U ]6 D' rtvb now,tvbnow,bttvbAmong the most picturesque of the lakes are Gaberoun and Umm al-Maa (the Mother of Water). Also there are two more beautiful lakes which are rarely visited by tourists. These are: Umm al-H'isan (the Mother of the Horse), also spelt as Oum El Hassan, located north of Gaberoun; and at-Tarhouna, about 11km from Umm al-H'isan. 2 `- i/ Y; w! q3 \" \- H1 N5.39.217.76" E2 E0 Q& h$ |8 u0 s!

Lake Gaberoun is one of the largest and most beautiful lakes of the great sand sea of Ubari; beautifully set amidst the magnificent sand dunes, with palm trees on one side and the ruins of the old village on the other. Most of the lakes of the Libyan interior are highly carbonated, enabling swimmers to easily float without exerting any effort. The content of salt is rather high: nearly five times saltier than seawater.5.39.217.76; z7 Q7 ^1 ~- A d1 ^7 u8 k.

Oases are formed from underground rivers or aquifers such as an artesian aquifer, where water can reach the surface naturally by pressure or by man made wells. Occasional brief thunderstorms provide subterranean water to sustain natural oases, such as the Tuat. Substrata of impermeable rock and stone can trap water and retain it in pockets, or on long faulting subsurface ridges or volcanic dikes water can collect and percolate to the surface. Any incidence of water is then used by migrating birds who also pass seeds with their droppings which will grow at the water's edge forming an oasis.
