The shading is the result of the satellite images taken at different times of the year. This shows different levels of flooding in the south basin Christian OBrien in the Genius of the Few provides the evidence that a dam was constructed and reservoir formed in the narrow valley east of Kfar Qouq, and that an overflow watercourse was built along the north bank of the south basin to take surplus water into the Wadi en Neirab, middle right.
