Junagarh Rock Inscription: The Mauryan Contribution 

The lake was a state-sponsored irrigation project initiated during the 4th and 3rd centuries BCE by Chandragupta Maurya. Its development occurred in two phases: 

  • Chandragupta Maurya: The lake was originally conceived and constructed under the orders of the empire's founder. His provincial governor in the Saurashtra region, Pushyagupta Vaishyadammed local rivers (the Suvarnasikta and Palashini) to create this massive artificial reservoir know as Sudarshan Lake.

  • Ashoka: Emperor Ashoka expanded the Canal by recognizing the lake's potential for wider agricultural benefit and further developed the site. 

    • The governor Tushaspha, a Yavana (Greek) official, added a sophisticated network of irrigation canals and conduits to distribute the stored water to surrounding farmlands.
