Many types of water resources are found in every region of Rajasthan. In ancient time water was supplied to the people from these resources and well maintained. The then rulers did many efforts of water collection and conservation. Efforts were made by Ranas of Udaipur. Lake of Jaismand is a good example of it.

It was built by the Maharana of Mewar Jai Singh, from 1687-1691 A.D. on river Gomati. Which is considered as the world’s largest man-made lake freshwater. The examples of the oldest methods of the conservation of water by turning and joining rivers and lakes can be seen in Mewar Chickalwas canal. It was built by Maharana Fateh Singh by building a dam on river Ahad to supply excess water of rainy season in Fateh Sagar. It is 6 km away from Udaipur. In this way 118 years ago water of Ahad river was reached to Fateh Sagar.

The serialy built ponds in 470 km are spread in valley area and join rivers by the then rulers in people’s interest. It is an excellent and praiseworthy work in the field of water collection and conservation which is being continue smoothly even today. The best example of water management resources in ancient times in the world can be seen in Udaipur Basin. To quote some of them as Govardhan Sagar, Dhood Talai, Pichhola lake, Amar Kund, Kumaria pond, Ranga Sagar Swaroop Sagar and Fateh Sagar. During the rainy seasons when all these water sources are filled to the brim, their water level gets merged.
