Obabika River

The Obabika River is located in central Ontario, Canada. It is south of Lady Evelyn-Smoothwater Provincial Park and west of Lake Temagami, within Sudbury District. It flows from Obabika Lake in a south-westerly direction and drains into the Sturgeon River. The Obabika River is remote and surrounded by undeveloped wilderness.

The river is characterized by long meandering sections through clay and sand valleys alternated by sections through eroded bedrock and marshes. The lower Obabika River is rather wide with several oxbow ponds, and obstructed by occasional log jams. Although the current is strong, the only noteworthy rapids occur immediately before its confluence with the Sturgeon River.

With its steady current and few portages, the Obabika River is a popular canoe route within the Temagami region, linking Lake Temagami and Lady Evelyn Lake via Obabika Lake to the Sturgeon River. It is part of the traditional indigenous travel network called "nastawgan", which has changed little over many centuries.
