This dam is built across the river Shimsha and Hemavati in Kunigal Taluk of Tumkur district. It was built by Krishnaraja Wodeyar IV, the king of Mysore under the guidance of his Diwan, Sir M Visweswaraiah & Ganesh Iyer in 1930s.
Can there be a dam with the gates always open and still the dam holds water to its capacity? "YES" says Sir M. Vishveshwaraiah andGanesh Iyer!!! Welcome to Markonahalli Dam !!
Situated around 100kms from bangalore, Markonahalli Dam is relatively unknown dam to bangalorians considering the speciality it possesses. Markonahalli Dam is a dam built across the river Shimshaand hemavati in Kunigal Taluk of Tumkur district. It was built by Krishnaraja Wodeyar IV, the king of Mysore under the guidance of his Diwan, Sir M Visweswaraiah in 1940. The main person who executed this unique project was Sri Ganesh Iyer.
The dam has 4 baby siphons and 2 big and 10 mini wood siphons which is designed in such a way that when the dam reaches its maximum capacity these siphons naturally allow water to pass through ever open gates!! Unlike usual dams where the crest gates are always closed to stop the flow of water, in this dam itsalways open and still the water doesnt flow unless the dam is full!!
The technology behind these siphons is simple. Siphons are the only way for water to pass through. And these work on the simple principle of air flow. The air hole shown in the picture is always closed and when dam reaches its capacity water is forced to pass through the siphons since there is no way for air to enter except the closed hole!! Hence this dam requires no actual maintenance!! And the water in the whole dam can becleared within one and half hour!!!
The dam is a beautiful place to visit as it has scenic beauty. Sunset seen at this place is awesome. Wonderful colors just after the sunset refreshed our mind. Its preferable to visit the dam in the evening to see its natural beauty.
