Vanceboro, Maine in eastern Washington County is the starting point of this trip. The launch is in a private area where the narrow river is literally a stone’s throw across from St. Croix, New Brunswick, Canada.
The river is managed by the St. Croix International Water Commission, “responsible for maintaining the natural, cultural, and historic integrity of the St. Croix boundary corridor between Maine and New Brunswick,” according to its website.
The river has substantial stretches Class I and II rapids, navigable throughout the open water season thanks to the dam on Spednik Lake, which regulates the flow for downstream hydroelectric generation.
Campsites are scattered along both sides of the river.
