Krishna Raja Sagar dam also known as KRS dam
It takes around 30 minutes to reach from Mysore city, Built across the river cauveri and there are 48 automatic gates that open and close at the rise and fall of water in the reservoir, in six sets, with eight in each. Each gate consists of a sill, lintel, and side grooves and plates, balance weight floats chains and pulleys, and inlet and outlet pipes. The gates are made of cast iron
The eight sets of gates are connected by means of chains and pulleys to a dead weight, which in turn is connected to a float, making up the 'balance weight' together, working inside a masonry well, both on the rear of the dam. The dead weight and float are placed one behind the other so as to have four gates on each side of it. When all the eight gates close the sluice , the balance weight moves to the top of its swing and the float to the bottom of the well. The well has an inlet pipe 1 ft (0.30 m) in diameter from the reservoir that allows water in when the reservoir reaches maximum permissible level causing the float to rise, the balance weight to fall pulling the gates up allowing discharge of water. In the same mechanism, the well gets emptied through an exit pipe when water level in the reservoir falls.
