Hamirsar Lake is the heart of Bhuj town and located in the western end of Kutch, Gujarat. Bhuj is known for hot and dry summers. This lake is considered an oasis between saline and arid Kutch. The kings built the lake to fulfil the domestic needs of people of Bhuj in ancient times. Hamirsar Lake was well developed with a channel and tunnels that used to carry water from three rivers to fill the town's water reservoirs. But after the earthquake of 2001 in Bhuj, this water system was gravely disturbed distorted.
The municipality and people of Bhuj took initiatives to revive the water system to its original form to fulfil the needs of its people once again. This was achieved in 2003. The water of Hamirsar Lake became potable. This manmade lake was named after Rao Hamir, a Jadega ruler who ruled around 450 years ago. Rao Hamir is considered the father of Rao Khengarji, the founder of Jadeja dynasty in Kutch.
