Upper Section – Cypress Hills Headwaters
The creek originates in the Cypress Hills, one of the highest points between the Rockies and Labrador, at elevations exceeding 1,100 metres. This upper section is characterized by cooler water temperatures and the rugged terrain of the hills, historically supporting brown trout populations. Tributary creeks such as Bone Creek (North Fork), Jones Creek, and Rock Creek feed into the system in this region.

Middle Section – Swift Current and Surrounding Area
As the creek descends from the hills and passes through the city of Swift Current, it transitions through agricultural valleys and coulees. The Duncairn Dam — 62 feet (19 metres) high and 2,000 feet (610 metres) long — impounds water in this portion of the watershed, creating reservoir habitat managed for recreational fishing. This dam maintains flow in the creek for stock watering, domestic use, and fish habitat, and the reservoir has seen increasing recreational use including boating and fishing.

Lower Section – Waldeck to Lake Diefenbaker
East of Waldeck, the creek turns north and follows a meltwater channel toward Lake Diefenbaker. This lower section flows through the semi-arid landscape of Palliser's Triangle and empties into Lake Diefenbaker, providing connectivity to the broader South Saskatchewan River system. This stretch and the associated reservoir areas are managed for walleye, northern pike, and yellow perch.
