Pembina River (Alberta)

The Pembina River is a tributary of the Athabasca River in central Alberta, Canada.

Pembina /ˈpɛmbɪnə/ is a Canadian French name for the high bush cranberry (Viburnum trilobum). The river gives the name to the Pembina oil field, an oil and gas producing region centered on Drayton Valley. The environmentalist group Pembina Institute also took its name from the river.

The Pembina River originates in the Canadian Rockies foothills, south of Cadomin, at Pembina Forks. It flows eastwards for 547 kilometres (340 mi) before it merges with the Athabasca River 64 kilometres (40 mi) west of the town of Athabasca, and has a drainage area of 12,900 square kilometres (5,000 sq mi). Water originating in the Pembina River goes through numerous merges until reaching the Mackenzie River, discharging into the Arctic Ocean.

Communities located along the Pembina River include Westlock, Sangudo, Entwistle and Evansburg. Pembina River Provincial Park is along the gorges of the river between Evansburg and Entwistle. Another protected area along the river is the Pembina River Natural Area, 20 kilometres (12 mi) northeast of Cherhill in aspen parkland.
