Beau Lake (Maine-Quebec)

The Beau Lake (in French: "Le Beau Lac") is a freshwater lake in the north–south axis through the Saint Francis River. The lake is the center of the boundary between:
 * Maine (United States): North Maine Woods, Aroostook County, Big Twenty, township T20 R11 & R12 Wels (northern part of the western shore of the lake) and T19 R11 Wels;
 * Quebec (Canada): administrative region of Bas-Saint-Laurent, regional county municipality (RCM) Témiscouata Regional County Municipality, in municipality of Rivière-Bleue, Quebec.

This lake is located entirely in the forest zone. In the story, the main economic activity was forestry. Since the mid-twentieth century, the resort and tourist activities have developed. This lake is particularly renowned for fishing and recreational boating in particular because of its mountainous landscape.

On the side of Maine, a forest road runs along the western shore of the lake. While the side of the Quebec, a few dozen homes are served by an access road to the northern half of the lake.

The lake is consisting of enlargement of the Saint Francis River. This lake is walled by steep cliffs:
