This paper describes the current situation of the reservoirs constructed on the Nistru River. A series of serious damages caused by the blocking the river dams have been analyzed, as the degeneration of large areas used in agriculture, forestry and pasture lands, resulting in worsening conditions for the reproduction of precious fish species, mudslinging and lowering of the active water accumulation volume, secondary pollution in proportions that exceeds self-sufficiency, greening, etc. The negative effects described and analyzed here continue to worsen. For example, putting into service of the pumped storage power plant from Naslavcea, near the dam, has further aggravated the ecological disaster. The authors have pointed out that the use of older methods, inherited from the periods of authoritarian administration, focused on the principle of subjecting at all costs the nature and its resources, in order to obtain as many benefits as possible without taking into considerations the possible consequence, inevitably creates major environmental problems, the solution of which increasingly difficult, costly and even impossible in some cases.
