Lake Diefenbaker in Saskatchewan is a reservoir created by damming South Saskatchewan River and Qu'Appelle River. The lake continues to drain into the two rivers, but the Qu'Appelle receives a much enlarged flow (in essence, a diversion of flow from the South Saskatchewan) due to the damming. Both rivers eventually drain into Hudson Bay via Lake Winnipeg and the Nelson River.[citation needed] Also located in Saskatchewan is Wollaston Lake, which is the source of Fond du Lac River draining into the Arctic Ocean and of Cochrane River draining into Hudson Bay and the Atlantic Ocean.[citation needed]
