Finally, the West Credit River is a headwaters tributary of the Credit River and is considered the crown jewel of coldwater brook trout fisheries in Ontario. This fishery significantly adds to the economic and social fabric of the province, with Ontario fisheries contributing a total of approximately $2.5 billion annually to the provincial economy.  MNRF’s own documents predict that climate change will reduce the number of watersheds in Ontario with brook trout by 50% by 2050.
