The Upper Qu'Appelle Watershed consists of the Qu'Appelle River, and several major creeks that run into it.
The Qu'Appelle River begins at the Qu'Appelle Dam next to Lake Diefenbaker on the South Saskatchewan River.
The Dam was constructed as part of the South Saskatchewan River Project in the 1960s to redirect water from the South Saskatchewan River through the Qu'Appelle Valley.
The River then runs east through the Qu'Appelle Valley, one of southern Saskatchewan's most recognizable features, passing through Eyebrow Lake and Buffalo Pound Lake.
Buffalo Pound Lake is a man-made reservoir which supplies the Buffalo Pound Water Treatment Plant, the source of drinking water for the Cities of Regina and Moose Jaw.
The Lake is home to Buffalo Pound Provincial Park, two bird sanctuaries, and several resort villages.
The Upper Qu'Appelle also provides water to the Mosaic Potash Mine in Belle Plaine, which extracts potash using steam, and to the neighbouring Yara Fertilizer plant.
The watershed's economy relies heavily on crop and livestock production.
The Upper Qu'appelle watershed ends just east of the Valeport Marsh, which joins Last Mountain Lake to the Qu'Appelle.
