5. Fateh Sagar Lake
Fateh Sagar Lake, placed in the city of Udaipur in Rajasthan, is an artificial lake named after Maharana Fateh Singh of Udaipur and Mewar and built to the north-west of Udaipur, located to the north of Lake Pichola in the 1680s, is one of the four lakes of the Udaipur city, namely the Lake Pichola (within the Udaipur town), Udai Sagar Lake (13 km to the east of Udaipur) and Dhebar Lake or Jaisamand Lake (52 km south east of Udaipur).
During drought conditions, when the rainfall is scarce, water storage in the lake is insufficient to meet the needs. To prevent loss of water due to evaporation, cetyl alcohol (hexadecanol) is sprayed over the lake surface.
