Kodaikanal Lake - Hydrology

Hydrology

An earthen dam was constructed to create the lake in a marshy where three streams flowed. The lake catchment experiences an average annual rainfall of 1650 mm. The climate is salubrious with summer temperatures of 19.8 °C (max) and 11.3 °C (min) and winter temperatures of 17.3 °C (max) and 8.3 °C (min). The out flow from the Lake forms the waterfall of 180 foot, called the Silver Cascade, 8 km downstream of the lake outlet.
