Piwei River

Piwei River is a river in the east-central part of the Canadian province of Saskatchewan in the boreal forest ecozone of Canada. It begins at the western end of the Porcupine Hills at Piwei Lakes and heads in an easterly direction through a glacier-formed valley and into the Etomami River, which is a tributary of the Red Deer River.

The river is accessed from Highways 984 and 983. Save for a small recreation park on the river's north bank, there are no communities nor settlements along its course. Big Valley Lake Ecological Reserve, one of Saskatchewan's Representative Area Ecological Reserves, is in Piwei River's watershed upstream along Big Valley Creek's course on the shore of Big Valley Lake.

Course
Piwei River begins south of the town of Porcupine Plain at an elevation of 511 m in a chain of several lakes called the Piwei Lakes at the western end of the Porcupine Hills. From the lakes, it heads east through the Porcupine Provincial Forest and glacier-formed valleys en route to its terminus at the Etomami River. The valley that the river follows continues east past Etomami River and is a natural portage to the Pepaw River, which follows that same valley farther east.
