The lake has been used as a water reservoir and Maharaja
Fateh Singh renovated it in 1888 AD at a cost of 6 lakh rupees after
the violent storm and heavy rain demolished the dam and, in the same
year, the Lake was named as Fateh Sagar Lake.
The Lake is surrounded by the Aravalli hills on the
three sides and is approachable by a motorable road, Moti Magri which
provides a beautiful and enchanting view of the lake. A stone dam of
800 m length is situated on the eastern side of the lake. Monsoon is
the main water source of this lake and three channels, one from Pichola
Lake, second from the Madar Lake, and the last one from Badi Lake leads
water to the Fateh Sagar Lake. Its 2800 feet long northeastern embankment
has three names, The Pal, the Drive and the Connaught Bund. The foundation
stone of the embankment was laid by the Duke of Connaught (son of Her
Majesty Queen Victoria). Hence the name as Connaught Bund.
A well planned lake, Fateh Sagar is the second drinking
water source for the citizen of Udaipur. Fatehsagar is 2.4 km length,
1.6 km width and 11.5 meter in depth. Its overflow during rainy season
(September) is a scenic sight. The lake is rich with flora like floating
macrophytes, the submerged macrophytes and the Phytoplanktons and fauna
such as Zooplankton, Benthos and Fish. The economically worth fishes
such as C. punctatus, C. reba, Catla catla, L. calbasu, Channa marulius,
Cirrhina mrigala, L. gonius, Labeo rohita, Tor khudree, and Wallago
attu are reported to be find here.
