About Groundhog
The Groundhog River is a river in Cochrane District and Sudbury District in Northeastern Ontario, Canada. The river is in the James Bay drainage basin and is a left tributary of the Mattagami River.
About 23 fish species have been identified in the Groundhog River, including self-sustaining population of lake sturgeon which are provincially rare to uncommon.
The Groundhog River is an advanced-level canoe route with several series of rapids and white water, in particular from the north of Groundhog Lake to the town of Fauquier; however, this river trip can be extended all the way to James Bay via the Mattagami and Moose Rivers.

Course
The river begins at Horwood Lake in geographic Keith Township in the Unorganized North Part of Sudbury District. It flows northeast over the Ontario Power Generation Horwood Lake Dam, used to control water flow and store water for hydroelectricity generating stations downstream in the drainage basin, to Groundhog Lake, then north under the Canadian National Railway transcontinental main line at the railway point and unincorporated place of Groundhog River, between the railway point of Joburke to the west and the community of Kukatush to the east. The railway line is used by Via Rail transcontinental Canadian trains, but none of these locations is served by the train.
