Omkareshwara temple was built by Lingarajendra II in 1820. The story goes that the King killed a pious Brahmin who protested against the King's misdeeds. The spirit of dead man began to haunt the King. To be set free from the curse, the King built this temple. He brought a Shivalinga from Kashi and installed it here.
There is a big water tank in temple complex and common carp fish are kept in it. You can see the bubbles coming out of water.
