General Information

The Hudson River-Black River Regulating District is a New York State public benefit corporation that protects public health and safety by regulating the flow of waters in two great neighboring watersheds in the Adirondack Region: the Upper Hudson River and the Black River.

Conklingville Dam on Great Sacandaga Lake

Established by the New York State Legislature (Article 15 Title 21 of the Environmental Conservation Law), the Regulating District works year-round to reduce flooding caused by excess runoff and augment river flow when river flows are low.
