In arid regions, the construction of hydraulic structures is relevant due to the shortage of water resources. Using the example of the Pskov hydroelectric power station, the results of the hydraulic calculation of the end structure of the energy spillway, made in the form of a water well of a unique design, are presented. A culvert wall, made with an initial expanding part and a sloping spillway part forming an oblique spillway, forms the well. The depths and speeds in each part of the water well and the parameters of the hydraulic jump are calculated. It is shown how significant damping of the water flow energy occurs in the selected water well design. The water velocity at the outlet of the water well becomes less eroded, decreasing several times. The critical depth is calculated when the width of the stream changes, the depth of water in the waterhole, the pressure on the waterhole wall, the height of the waterhole wall located along the spillway face of variable width, the interface of the water flows behind the waterhole wall.
