Abstract: With the purpose to ensure the hydroplus fusegates proper operation it is necessary to accumulate the additional volume of water in the reservoir, irrespective of the flood size. The authors suggest pass the flood with the help of automatic action valves while the water level is low. When the height of water on the lip of a spillway starts to exceed the calculated level of water, the shield is inclined around junction under the small angle, opening the input of the dam and water passes downstream under the shield. During the drain moment force of pressure of water decreases, the shield goes aside position of way out. The moment of force of pressure of water again overcome the moment of force of elasticity of the spring and the shield again turns this time under bigger angle, than at the first opening, because there is increase of water level in the reservoir. Thus amplitude of oscillation of the shield will increase step by step till the elapsing way out will be equal to an output of the torrent. During all this process the dam will work by variable output. It is obvious, that the additional volume of water will be accumulated in the reservoir.
