Little Madawaska River (Ontario)

The Little Madawaska River is a river in the Saint Lawrence River drainage basin in the Unorganized South Part of Nipissing District in northeastern Ontario, Canada. The river is entirely within Algonquin Provincial Park, and is a right tributary of the Petawawa River and not a tributary of the nearby Madawaska River.

Course
The river begins at Lake La Muir in the geographic township Freswick Township and flows northeast to Hogan Lake. It continues northeast from the lake controlled by a small dam to Phillip Lake, from which it also continues to flow northeast controlled by a dam. The river then empties into Radiant Lake on the Petawawa River in Deacon Township, near the unincorporated place of Odenback. The Petawawa flows via the Ottawa River to the Saint Lawrence River.
