In 2012 the construction of a weir, a bridge and a fish pass on the river Głomia in the Skórka village was completed. The new weir allowed to continue operating hydroelectric power station (12 kW). The construction of fish ladders allowed the migration. The analysis of water flows by the barrage indicates the need for modernization of hydroelectric power. The problem on the barrage is also to provide sufficient current attractant in order to identify a suitable way for migratory fish. The analysis of the technical solutions proposed the construction of a second fish pass. The paper presents a detail analysis of the modernization of the barrage yet, taking into account all the elements constituting the upper and lower positions of the structure. Reconstruction of hydrotechnical objects, technical condition of which requires modernization should take into account the performance characteristics of all elements of the barrage to avoid the need to improve the operation of the elements already modernized. The repair work should be different scenarios that may occur during the lifetime of barrage.
