The lake is centrally located, over a space of 1.5 sq. km. A place of prominence in the early years of the century, the lake was then known as "Halsur" or "Alasur". It extended over an area of 125 acres and was constructed by Kempe Gowda during the second half of the second century. It is a major tourist attraction with a boat club where you can hire out cruises with stops at some of the tiny islands that dot the lake.
