  The Jaisamand Dam with its large lake is located by the side of the Udaipur - Banaswara highway, roughly 52 km from Udaipur City, Rajasthan. It was built across the river Gomti during the reign of Maharana Jai Singh of Mewar, who opened the dam in 1691 and distributed gold equal to his own weight in charity to the workers, thus following the tradition and chivalry of many of the prominent Indian kings of the the medieval period.
Jaisamand lake, also known as Dhebar Lake, is the second largest artificial lake in the world after Aswan dam in Egypt, extending over an area of thirty-six square kilometers. Nine miles in breadth, 102 feet deep and having a circumference of 30 miles. This Marble Dam is 300 Meters long and is a part of the Heritage Monuments of India. This is one of the very old dams of India which still stands in good shape without any seepage or any other structural damages even after 300 years of its existence.
During the reign of Maharana Jai Singh the lake was designed and built to improve agriculture and water management in Mewar’s southeastern corner, and it was named after him. The work of this dam began during his regime but was completed in later years. The area consists of eleven islands some of which are inhabited by the tribe of Bhil Minas.
Jai samand Lake is the main water supplier of the city of Udaipur. The gross basin area up to the Jaisamand dam site is 1787 km2. Droughts are a normal feature of the basin and extreme events have become more frequent in recent decades due to over utilization of water and truancy of Monsoon.
This dam was originally meant for recreation and daily water requirements of of the royal families, but from 1960 onwards it is being used to irrigate 1650 hectares of land. Thee is a wildlife sanctuary near by stretching over sixty-four square kilometers and is rich in fauna with over 300 bird species. Attracted by the vast expanse of water of Jaisamand lake, a host of small birds, local and migratory, roost the sanctuary. There are also many exotic animals. It used to be a favorite place for hunting by Maharajas in the bygone days.

-Cambrian age). This type of quartzite, quarried locally,
was used in the masonry work. Besides, marble from Rajnagar, 67 km away from the site was extensively used for constructing cenotaphs, the steps leading to the temple and the bathing ghats. The spillway located on a saddle on the left bank is designed to pass 3849 cumec  of water. Another saddle a little above is used to serve as natural auxiliary spillway, in case of unusual flood discharge. During 1973 floods which carried more than the designed discharge of the spillway, this saddle helped in spilling of extra discharge that saved over-flowing of the dam. This indicated the accuracy of the survey conducted 300 years
Jaisalmand lake and the islands are nature's gift where the one can not fathom the nature's bounty. The soul-stirring ambiance - the Maharaja's palace,etc, the placid lake and the beautifully carved cenotaphs and the lush green surroundings will make the visitors go into a trance – a perfect union with nature's wonderful creation.
