Built by Maharana Jai Singh in 1678, Fateh Sagar Lake is one of the many artificial lakes in Udaipur. It is roughly about 1 square km in size, but the size tends to vary depending on the season and the rainfall in the area. Fateh Sagar Lake is named after Maharana Fateh Singh who extended the lake during his reign. Located at the foothill of Moti Magri, this lake is very important not only in terms of tourism but also sustaining the water supply in the city.
