Costigan Lake [2] is a lake in northern Saskatchewan, Canada. It is the source of the Geikie River, which is the primary inflow for the bifurcating Wollaston Lake.
Costigan Lake Lodge, which is a fly-in only camp and outfitters, is "located on a sandy pine-covered ridge, in a peaceful bay on Costigan Lake". [3]
Costigan Lake is a large, irregularly shaped lake with many bays, peninsulas, and islands in the Canadian Shield. Its primary outflow is the Geikie River [4] which flows out from the eastern end of the lake. [5] The river flows eastward into Wollaston Lake. Wollaston Lake — with its two outflows — drains through the Churchill River system to Hudson Bay and the Mackenzie River system to the Arctic Ocean. [6]
Fish commonly found in Costigan Lake include walleye, northern pike, yellow perch, burbot, cisco, lake trout, lake whitefish, longnose sucker, and white sucker. [7]
