Ancient and historic land use was by no means confined to this protected area, however. The north shore, for instance, connects Great Bear Lake to important areas for hunting caribou and muskoxen , and oral histories about this area detailed interactions between Dene and Inuvialuit. Important fisheries were located where rivers meet the lake. As with the north shore, the south shore and this fishery in particular encouraged contact between different Indigenous peoples.
Elsewhere, fast running waters at the meeting of Great Bear Lake and Great Bear River kept the surface from freezing, enabling year-round fishing for cisco — a practice that dates back at least 6, years.

By , three mines had opened on Great Bear Lake. The largest — the Eldorado mine — was located at Cameron Bay later Port Radium , the site of the original find. Radium and silver were mined from Great Bear Lake until the Second World War , when labour shortages and decreased demand forced the mines to close by In , the Canadian government secretly reopened the principal Eldorado mine in order to extract uranium which had previously been disposed of as waste.
Some of the uranium went to the Manhattan Project — an American research program that aimed to create nuclear weapons during the Second World War. Uranium mining continued on Great Bear Lake until the Eldorado mine closed again in , while post-war silver mining took place between and Most of the mine workers came to Great Bear Lake from southern Canada or farther afield.
Mining companies hired Sahtu Dene as prospectors to find new ore deposits. Dene also sold meat and fish to people living and working at Port Radium, although many of the newcomers liked to fish and hunt for sport.
