Fine water level regulation is made by the tilting leaf with overflow, while the downstream water supply of large amounts of water is performed by the radial gate with gradual opening and bottom flow. The weir capable of raising the retention level at El. 87,50 m A. O. D. in Stage I of the construction, at El. 89,00 m A. O. D. in Stage II, at El. 90,50 m A. O. D. in Stage III and at El. 91,20 m A. O. D. in perspective. There is no damming in case of flood waves. The height of the tilting leaf is 5 m and it is capable of retaining 3,3 m water head. The position of it is controlled by a power-roll based on the radial gate. The river bed downstream of the weir is a 30 m long tail- race lined with concrete and closed at its downstream end by a diphragm wall of reinforced concrete and by rip-rap. Between the openings there is a pillar with 3,6 m width, whose shape is a new solution also from the theoretical aspect. Its „fish-tail" shape reduces the effect of the separating eddies acting on the bottom of the bed. This shape is a service patent of the Institute for Hydraulic Planning. The weight of the moving part of one closure mechanism is 136,4 tons. There are two emergency closures for repair and maintenance works: a cross-beam closure at the upstream, and a modern needle weir at the downstream part of the weir. The hydroelectric power station is built alongside the weir on the right bank. It is equipped with four horizontal-shaft 107 r. p. m. tubular turbinqs of 4,3 m runner diameter. Each is built together with its generator.
