Dam Registration and Dam Recordation

Dam Registration

All dams in the State of Connecticut must be registered.  Please review the Dam Registration Fact Sheet. 

Before filling out a dam registration form, you should verify that you or a former owner did not already register the dam: Dam Safety Inventory of Dams in Connecticut

To assist in the completion of a dam registration form, a diagram of a typical dam is available.

Contact the DEEP Dam Safety Regulatory Program at (860) 424-3706 or by email at DEEP.DamSafety@ct.gov to receive a dam registration form.
