Lacombe Lake is a long, narrow pothole lake located in Lacombe County in central Alberta, situated approximately 5 km north of Blackfalds and 15 km north of Red Deer. The lake stretches roughly 3 km in length with a maximum width of around 500 m and a maximum depth of approximately 3.0 m. Its shoreline is characterized by numerous bays and points that give it a distinct, irregular shape. The lake sits within the Aspen Parkland ecoregion, surrounded by a mix of trembling aspen, oak, mixed tall shrubs, and intermittent fescue grasslands, with much of the surrounding land consisting of private farms and homesteads.

Motorized boats are not permitted on the lake, which keeps conditions calm and quiet. The Central Alberta Rowing Club operates on the water, and their eight-person rowing shell represents the fastest craft paddlers are likely to encounter. A public access point with a boat launch provides free entry for canoes, kayaks, and paddleboards. Trails exist on the west and south ends of the lake, and the Trans-Canada Trail (Great Trail) runs nearby, offering the option to combine paddling with a walk. There are no public campgrounds around the lake, as most surrounding land is privately held.

A typical outing on Lacombe Lake suits one to three hours of paddling. The lake's shallow depth and relatively compact size make it well suited to recreational paddlers and beginners. The lake was historically known as Jackfish Lake, a name reflecting the presence of northern pike; the name was changed to Lacombe Lake in 1975. The Lacombe Lake area falls within Treaty 6 territory and was historically used by the Samson and Ermineskin Cree Nations for hunting and travel.

Wildlife viewing is a notable draw, with abundant waterfowl present on and around the lake. Recorded species of interest include Common Loon, Red-necked Grebe, Bald Eagle, Marsh Wren, and Gray Catbird, along with various warblers and sparrows. The lake is not considered a popular fishing destination, though northern pike are present and walleye and burbot may also occur. County Waters Kayaking, a local outfitter serving Lacombe County, includes Lacombe Lake among the waters where it offers tours and rentals, providing an option for paddlers who prefer guided or rental experiences.
