This is a unique watershed that straddles the Continental Divide - water flows to both the Pacific and the Arctic Oceans: Arctic Lake drains northwest into the Parsnip River thence the Peace River and eventually into the Arctic Ocean; Portage and Pacific Lakes sit at the headwaters of Bad River (James Creek), which drains into Herrick Creek thence McGregor River, which empties into the Fraser River on the way to the Pacific Ocean.
