The Matabitchuan River is a river in Nipissing and Timiskaming Districts, Ontario, Canada.
The river begins at Rabbit Lake in Nipissing District at an elevation of 288m (945feet). It flows northeast over Rabbit Lake Dam and through Rabbit Chute to take in the left tributary Lorrain Creek. The river continues northeast, passing into Timiskaming District, to Fourbass Lake at an elevation of 274m (899feet) and then empties into the west side of Lake Timiskaming, 1km (01miles) south of the mouth of the Montreal River. A dam controls the outflow of Fourbass Lake, and some of the water from the lake is diverted through a penstock from a point 47.1214°N -79.4983°W southeast of the river outflow to the Ontario Power Generation Matabitchuan Generating Station.[1] Highway 567 leads from the community of North Cobalt (in Temiskaming Shores) to the nearby Lower Notch generating station.
