First Mustus Lake[1] is a lake in Meadow Lake Provincial Park[2] in the Canadian Province of Saskatchewan in the boreal forest ecozone of Canada.[3] The lake is the first of four lakes in a row named Mustus in the Rusty Creek[4] watershed. The other lakes are Second, Third, and Fourth Mustus. Rusty Creek and the lakes are part of the Waterhen River drainage basin. The Waterhen River is a tributary of the Beaver River, which flows north into Lac Île-à-la-Crosse and the Churchill River, a major tributary in the Hudson Bay drainage basin.[5] Highway 224 provides access to both First and Second Mustus Lakes.[6]
There are two main inflows for First Mustus Lake and one outflow. At the south-east corner of the lake, Rusty Creek flows out and into the next lake downstream, Rusty Lake. Dennis Creek,[7] which has its source in the Mostoos Hills,[8] flows into the north-east corner. The river from the other three Mustus Lakes and Peitahigan Lake flow into First Mustus at the western end. Kimball Lake is directly south of First Mustus, Rusty Lake is south-east, and Second and Third Mustus are to the west.
