Lying 35 kilometres south of Pickle Lake in Northwest Ontario, Lake St. Joseph's large size and remote location contribute to excellent freshwater fisheries; particularly known for its abundant walleye and trophy northern pike.
Due to its wilderness designation, access is restricted. Anglers wishing to fish Lake St. Joseph must receive a special permit from the Ontario Ministry of Natural Resources in addition to other licenses needed. In fur trade days Lake St Joseph was part of a canoe route running west from James Bay to Lake Winnipeg.
