Dam Safety Permit/Waterway Construction Permit
General Info - Statewide Permit
The Maryland Dam Safety Division issues waterway construction permits for new dams and ponds and permits for alterations to existing impoundment structures. The major goal of this permit is to ensure that dams are built and operated properly to protect public safety.
Anyone who wishes to construct, reconstruct, repair, or alter a dam, reservoir, or similar waterway obstruction must obtain a permit prior to beginning any work (certain small ponds are exempt from this permit). Permits are reviewed and issued in two phases.
