Ruisseau Narsaaluk is a remote stream located in the Nord-du-Québec region of Quebec, Canada, situated at approximately 58.67–58.71°N latitude and 65.10–65.15°W longitude. This places it deep within the subarctic landscape of northern Quebec, in the vicinity of Kangiqsualujjuaq, roughly 26 kilometers from that community. The stream flows through one of Canada's most wild and untouched wilderness regions, characterized by the rugged boreal and tundra terrain typical of the Ungava Peninsula. Its extreme northern position means it experiences a true subarctic climate, with a very short open-water season, long frozen winters, and the dramatic seasonal swings that define fishing in this part of the world.
