Whiteshore Lake is a salt lake in the west-central part of Saskatchewan, located approximately 15 kilometres northwest of the town of Biggar. It sits within the North Saskatchewan River drainage basin and is classified as a post-glacial, evaporative playa lake. The lake covers 2,015 hectares with a maximum length of 17 kilometres and a shoreline of 48 kilometres, sitting at a surface elevation of 637 metres. It has no outflow.

As a salt lake, Whiteshore Lake supports no fish. The high salinity is a defining characteristic of the water body and shapes the overall paddling environment. The climate of the region is warm-summer humid continental, which influences the paddling season.

Along the northern shore, the Palo salt mine has operated since 1934, extracting sodium sulphate — an industrial presence that is visible from the water. The community of Palo and Reginald G. Whitford Memorial Park are also situated on the northern shore. Access to the lake and its amenities is provided via Highway 14.

Given the lake's salt content, paddlers should be aware that contact with the water may be irritating to skin and eyes, and equipment exposed to the brine should be rinsed thoroughly after use. The absence of fish and the industrial mining operation on the northern shore define much of the character of this lake, distinguishing it markedly from typical freshwater paddling destinations in the province.
