The northern most point of Moose Mountain Creek's watershed is near McLean, which is only 41 kilometres (25 mi) away from Saskatchewan's capital, Regina.

[10] Moose Mountain Dam, which was built in 1937, is at the south-east corner of the lake, near Lost Horse Hill.

Dykes and culverts were built south of Kisbey to protect the village and control the river's flow.

From south of Kisbey, the river roughly parallels Highway 13 towards Arcola where it leaves the floodplain and flows into a valley, the Moose Mountain Creek Spillway.

It continues east until it crosses Highway 9, at which point it takes a more southerly route and flows into a Grant Devine Reservoir.

Moose Mountain Creek cuts through the park from the north-east to the south-west corner at which point it goes under Highway 711 and into the lake.

It is about one square mile in size and sits in the valley at the confluence of Moose Mountain and an unnamed creek that comes in from the west.
