Harbor Hill Marina

Harbor Hill Marina is a boat ramp access point on the Niantic River in East Lyme, Connecticut. The Niantic River is a medium-sized waterway classified as a Stream Order 5, flowing through southeastern Connecticut with a total length of 5.23 miles. The river features a moderate gradient of 20.1 feet per mile and maintains an average flow of 53.22 cubic feet per second with relatively slow average velocity of 0.71 feet per second, making it generally suitable for recreational boating activities.

The access location at Harbor Hill Marina provides entry to a river system that ranges in elevation from 0.80 meters to 32.70 meters. Being situated 18 miles from the river mouth, this launch point gives paddlers and boaters access to a significant portion of the Niantic River's middle and upper sections. The river's moderate gradient and stream characteristics suggest generally manageable water conditions for recreational use, though conditions may vary seasonally with water flow and weather.

Paddlers and boaters using this ramp should be aware that this is a medium river system with its own hydraulic characteristics. The relatively slow average velocity and moderate slope suggest this is not a rapid-filled whitewater system, but rather more suitable for recreational paddling, fishing, and motorized boating in calmer conditions.
