Dams regulated by the Department are classified based on size and hazards. The size classifications are large, intermediate, small, and very small. Hazard classifications are high hazard, significant hazard, and low hazard.
These regulations specify the administrative process for obtaining a permit for either a new dam or the alteration, repair, or removal of an existing dam. The items required to be submitted to the Department as part of the permit application package are also given in the regulations as well as some general design criteria a dam must meet.
