At the southern end of Newfound Lake is the lake outflow, the Newfound River which is a fly-fishing only river plus it has a walking/bicycling trail that parallels the river as it flows down to Bristol, NH and into the Pemigewasset River. There's a concrete dam close to the start of the Newfound River and a second dam down closer to Bristol that can be seen from Route 3A.

The Newfound Lake Dam and the Lakeport Dam in Lakeport, Laconia are both controlled by the NH-DES and used to seasonally lower and raise the water levels on Newfound Lake and Lake Winnipesaukee. Without these two dams both Newfound Lake and Lake Winnipesaukee would still exist but at an unknown lower level.
