Potanipo Lake Boat Ramp in Brookline offers public access via a well-marked launch on Mason Road near Route 13, with easy seasonal access for both motorboats and kayaks.

The 136-acre lake features a navigable channel on the far shore with beaver dams that can be portaged, making it suitable for paddlers seeking quieter water away from powerboat traffic. No personal watercraft are permitted at this state-managed facility.
