Course
Beaver River originates in Beaver Lake, south of Lac la Biche and the Northern Woods and Water Route. It flows south and then turns east and flows toward the Alberta/Saskatchewan border, which it crosses south of Cold Lake. At this point, the Beaver river has an average annual discharge of 653,000,000 m3[1]. It continues east in Saskatchewan on to the village of Green Lake, where it turns north and flows toward the Lac Île-à-la-Crosse in the Churchill Lake system. From here, its waters are carried to the Hudson Bay by the Churchill River.

Conservation and Development
Beaver River flows through a predominantly flat area with rolling and undulating hills, and many lakes are drained through meandering streams into the river (among the larger ones are Lac La Biche, Pinehurst Lake, Cold Lake, Primrose Lake.
Lakeland Provincial Park, Moose Lake Provincial Park and Cold Lake Provincial Park all lie in the river basin on the Alberta side, while the Meadow Lake Provincial Park protects a large area in Saskatchewan.
The Cold Lake Area Weapons Range occupies much of the northern area of the river basin.
