A dam has been constructed across Hemavati River, an important tributary of the Kaveri. The dam is located at Gorur, near Hassan in Karnataka. Built in 1979, the reservoir has been providing water for drinking and irrigation purposes for the people of Hassan district. Hemavati Dam is very vast and covers a catchment area of 2,810 sq. km. This dam is 4,692 m long and 58.5 m high. The gross storage capacity of this dam is 1,050.63 mcm. The reservoir has six large radial spillway gates.
Hemavati dam presents a beautiful look to the visitors, especially during rainy season, when the spillway gates are opened to release the flooding waters that gush out like froth. A garden covered with a green lawn right next to the dam enhances the beauty of the atmosphere as well as the location. The garden is often visited by local people. A visit to the dam in the early hours of the morning is highly gracious, pleasant and inspiring. Various water birds keep flying and diving into the waters. The temples of Sri Paravasudeva and Sri Yoganarasimha are very close to the dam and are popular tourist destinations. The best time to visit Hemavati reservoir is the period between October and March.
