It is one of the four lakes of the Udaipur city; the other three lakes are: 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).
Within the confines of the Fatah Sagar Lake, there are three small islands.; the largest of these is the island called the Nehru Park (4 km2 area), which is a popular garden with a restaurant and a zoo, the second island (0.06 km2 area) houses a public park with an impressive water-jet fountain and the third island (1.2 km2 area) is the address for the Udaipur Solar Observatory (USO). The Nehru park is accessed by inboard motor boats from the bottom of Moti Magri. Blue waters of the lake and the backdrop of green has given the soubriquet of ‘the second Kashmir’ to Udaipur town.
