Madge Lake is a freshwater lake located in eastern Saskatchewan, 18 km east of the town of Kamsack and just a few kilometres west of the province's eastern boundary. Road access to the lake is via Highway 57, which passes by the south shore of Madge Lake as it connects Highway 5 to Manitoba Highway 83.

Highway 5 is a major highway in the Canadian province of Saskatchewan. It begins in downtown Saskatoon and runs eastward to the Manitoba border near Togo, where it becomes Provincial Road 363. The highway is approximately 393 kilometres (244 mi) long. Between the early 1900s (decade) and 1976, Provincial Highway 5 was a trans-provincial highway travelling approximately 630 kilometres (390 mi) in length. At this time it started at the Alberta border in Lloydminster and traveled east to the Manitoba border.
