decreasing safety of these dams and their facilities, accidents will occur. We cannot allow this to happen. Further, although possible removal of many such dams (which also requires corresponding design, administrative and construction activities and financing, respectively) seems to be a solution, their subsequent building if needed will be much more difficult and expensive. Hence, similar decisions with long-term effect have to be made very carefully. We are glad to find that currently, there is the general expert and administrative will in Bulgaria for solving the problems with the status and operation of the small dams.
