LAKE THARTHAR

'Lake Tharthar', known in Iraq as 'Buhayrat ath Tharthar' (Arabic: بحيرة الثرثار), is a lake situated 120 kilometers north of Baghdad between the Tigris and the Euphrates rivers. The lake is deep and nutrient poor; there is very little vegetation except for sparse shrubs, some dense patchs of growth and scattered ''Ziziphus'' trees. The area is farmed thanks to the use of tube-wells. A few sheep also graze in the area. Due to the farming the topsoil is damaged by vehicles and the lake is threatened due to overfishing.
Tharthar also the wife of Stilgar, Naib of Sietch Tabr in the hit book Dune by Frank Herbert
