This paper aims to identify deforested surfaces in the studied area, fact that determines the intensification of soil erosion process and furthermore it increases the alluvial effluent witch disrupts the functioning of the hydroelectric power plant in the projected parameters. In 1990 the area covered with forest vegetation in the Sihastria watershed was about 147 ha, but due to the clear-cut on the areas that were returned to the right owners, the wooded area was reduced to 100 ha, from which, as a result of excessive cuts on 39 ha the density of the trees is very low. The Sihastria small hydroelectric power plant is located at the confluence of the Sihastria stream with Negrisoara River (25.5253090 eastern longitude and 47.19178470 northern latitude). The hydropower plant constructive elements consist of: intake, desilting tank, fore bay tank, penstock pipe, and power house and tailrace channel. In order to determine the causes that led to the clogging of hydrotechnical constructions, trips were carried out in the analyzed watershed, during the vegetation seasons of the last three years (2015-2017).
