Ketchemonia Lake is a medium-sized lake located within Duck Mountain Provincial Park in southern Saskatchewan, approximately 82 kilometres northeast of Yorkton. The lake covers 619 acres with a shoreline length of roughly 10 kilometres, giving it a moderately compact footprint suitable for day paddling. Its position within the provincial park means it sits within a managed natural area, and paddlers should be aware that park regulations apply.

The lake falls within Saskatchewan's Southern Fishing Zone. Nearby water bodies include Madge Lake approximately 4 kilometres away, along with Bear Head Lake and Harold Lake in the immediate vicinity, suggesting the area contains a cluster of lakes that could be of interest to paddlers exploring the Duck Mountain region more broadly.

Beyond these basic facts, detailed specifics regarding Ketchemonia Lake's access points, launch facilities, hazards, water quality, or recommended routes are not well documented. Paddlers planning a trip would be well advised to contact Duck Mountain Provincial Park directly for current access conditions, any applicable use permits or restrictions, and information on boat launch availability before visiting.
