TheNorthwest Branch Saint John River (French:Décharge du Lac Frontière) is a 15.5-mile-long (24.9 km)[1] river primarily inAroostook County, Maine, USA. Its origin (46°42′04″N69°59′55″W / 46.7012°N 69.9987°W /46.7012; -69.9987 (Northwest Branch Saint John River source)) isFrontier Lake (Quebec-Maine) inQuebec,Canada. After crossing theCanada–United States border, the Northwest Branch runs south close to the border until it picks up itstributary, theDaaquam River, which also flows out of Canada. The Northwest Branch then runs generally eastward to itsconfluence with theSouthwest Branch to form theSaint John River.
Has current flowing in:
On the Canadian side, theroad 283 runs along the Canada-US border on 6.4 kilometres (4.0 mi) and crosses the "Northwest Branch Saint John River" at the South East side of theFrontier Lake (Quebec-Maine).
On the US side, a road fromFrontier Lake (Quebec-Maine) moves Eastward through the mountains. In addition, a road runs on the North bank on a river segment, downstream of the confluence of theDaaquam River and serves the township T11 R17 WELS in theNorth Maine Woods.
The river segment of 1.1 kilometres (0.68 mi) between the bridge of theroad 283 and the Canada-US border is considered an extension ofFrontier Lake (Quebec-Maine). Consequently, the "Northwest Branch Saint John River" officially rises at the US border and not at the mouth of Frontière Lake in the municipality ofLac-Frontière, Quebec.
This source is located at 6.5 kilometres (4.0 mi) Southeast of Lac Etchemin and 13.5 kilometres (8.4 mi) Northeast of the Canada-US border.
From its source, the "Northwest Branch Saint John River" flows on 20.7 kilometres (12.9 mi) of which 1.1 kilometres (0.68 mi) inQuebec and 19.6 kilometres (12.2 mi) in theMaine:
Higher courses of Northwest Branch Saint John River (segment of 1.1 kilometres (0.68 mi) inQuebec)
Intermediate Course of the Northwest Branch Saint John River (segment of 9.9 kilometres (6.2 mi) inMaine, up to the confluence of theDaaquam River)
Lower course of the Northwest Branch Saint John River (segment of 9.7 kilometres (6.0 mi) downstream of the confluence of theDaaquam River)
"Northwest Branch Saint John River" flows on the Southwest bank of theSaint John River. This confluence is common with that of theSouthwest Branch Saint John River (coming from South).
From the confluence of the Northwest Branch Saint-Jean River, theSaint John River flows Eastward and Northeast throughMaine, then East and Southeast throughNew Brunswick. Finally, the current flows on the North bank of theBay of Fundy which opens to the Southwest on theAtlantic Ocean.
