Since its establishment, the city of Jaipur had faced water scarcity problems. Ruler of Amber, Sawai Jai Singh, decided to build a man-made lake to help fix the water problem of the forts of Amer and Jaigarh and for the people of Amer. Water being a precious commodity in the area, the lake was “hidden” by the Aravali range, and was visible from neither fort nor city.
A rectangular-shaped lake was constructed, which in time was filled by the monsoon rains. The lake is divided into two parts – Upper and Lower Sagar – and is connected with some step wells that fill up with water once the lake reaches its full capacity. This lake has long been filling the water requirements of the people of the region and is a preferred picnic spot for many.
