Last Mountain Lake — also known as Long Lake — is a massive, glacier-formed prairie lake in south-central Saskatchewan, stretching approximately 93 kilometres long and up to 3 kilometres wide. Formed roughly 11,000 years ago by glaciation, it sits about 40 kilometres northwest of Regina and extends northward nearly to Nokomis. It is the largest naturally occurring body of water in southern Saskatchewan, with only the man-made Lake Diefenbaker surpassing it in size. The lake drains southward into the Qu'Appelle River via Last Mountain Creek, which flows past Craven. Its sheer scale is remarkable — portions of the lake fall within eight different rural municipalities. Two regional parks, two provincial parks, and three recreation sites line its shores, making it one of the most popular recreational and fishing destinations in the province. The lake draws anglers from across Saskatchewan and beyond, with a well-earned reputation for trophy-class walleye and northern pike.
