History of Krishna Raja Sagara Dam
Mysore and especially Mandya used to get extremely dry during summer season, as a result of which, in 1875-76, there has been a severe draught in those areas. The draught led to irrigation problems for the lack of water and most of the inhabitants of the area had to migrate to different locations to get rid of the draught. In such moment, Kaveri River was seen as a great potential source of water, which would also help for irrigation.

The Chief Engineer of Mysore M. Visvesvaraya presented a plan of the dam to construct it on the Kaveri River near Kannambadi village. At first, he was obstructed by government from executing his plan to build the dam. So, later he approached to T.Ananda Rao, the Diwan of Mysore and the Maharaja Krishna Raja Wadiyar IV to reconsider the project and help him to execute it; later government was also consented on this project. Finally, the construction began in the year 1911 on November; almost 10,000 workers were employed to execute the entire project. A mortar named surkhi was used instead of cement to build the dam. The construction of the dam got finally completed in 1931. The dam has walls with a length of 2621 meters and height of 39 meters.
