The naturally undulating terrain of Bangalore city, with its hills and valleys, lends itself perfectly to the development of lakes that impound rainwater, store it for future use and ensure ground water recharge. Lakes are thus live ecological systems, and play a crucial role in the supporting life, including human.

Lakes in Bangalore were designed in cascades from higher to lower elevations; as a lake overflowed the excess water would flow into the next lake in the cascade. The flow of water is from North to South-east as well North to South-west along the natural gradient of the land.
