Davey Lake is a small lake in the Canadian province of Saskatchewan in the Churchill River drainage basin. The lake is surrounded by boreal forest and muskeg. It is south-southwest of the town of La Ronge and directly west of Lac la Ronge in the Northern Saskatchewan Administration District. There is no road access. Its outflow is a small creek that leaves the lake at the northern shore and flows a short distance to Biden Lake. Biden Lake's outflow is a tributary of Highway Creek, which flows into Potato Lake. Potato River flows out of Potato Lake and into Lac la Ronge.
