The Rivière Baudoncourt is a remote wild river located in Quebec, Canada, associated with the Rapid Lake outfitting operation in Nunavik. The river is characterized by long shoals, deep pools, and whitewater ranging from Class I to Class III, offering a varied and technically engaging experience for paddlers. The terrain reflects glacial origins, with ice-carved valleys framing the waterway and crystal-clear water throughout.

The river is accessible from ice-out in spring through mid-September, which represents the practical paddling season given its northern latitude. The scenery changes frequently along the route, with the combination of flatwater shoals, pools, and whitewater sections providing a dynamic experience. The water is described as pure and crystal clear.

Wildlife and natural features are a notable aspect of the river. The Baudoncourt supports a population of wild Arctic char, with most fish in the 8 to 11 pound range and occasional individuals reaching 15 pounds. The presence of active fish throughout the open-water season is a defining characteristic of the river's ecosystem. The broader region is associated with Nunavik wilderness, and the outfitter Rapid Lake also operates polar bear safaris and fjord expeditions in the surrounding area, indicating the river sits within a genuinely remote subarctic landscape.

Given the river's remote location in Nunavik and its association with a fly-fishing outfitter, paddlers should anticipate that access is likely managed through the Rapid Lake operation. The whitewater reaches Class III in places, which warrants appropriate skill and equipment for paddlers venturing onto the river. No specific put-in or take-out locations, portage information, or paddling-specific regulations have been documented.
