Watson Lake is a sizeable lake located approximately 4 kilometres north of the community of Watson Lake in the Yukon Territory, Canada. It is the largest lake in the immediate area and sits within a forested landscape. Access is available via the Alaska Highway, with a turnoff just past the junction with the Robert Campbell Highway at the north end of town. From the highway, a dirt road leads roughly 4.6 to 5.2 kilometres to the campsite area, with the boat launch situated on the south side of the lake within the territorial campground.

The lake supports canoeing, boating, and water skiing during the summer months, making it a multi-use water body where paddlers should be aware of motorized boat traffic. A formal boat launch is available at the campground, providing convenient access for canoes and kayaks. The campground itself offers facilities for those planning overnight stays.

Fishing on Watson Lake targets arctic grayling, lake trout, and northern pike, and a Yukon fishing licence is required. The surrounding forest provides a backdrop typical of the southern Yukon boreal zone. Summer activities on and around the lake are varied, and the area draws visitors for swimming and picnicking as well as paddling.

The lake freezes over in winter, at which point it transitions to ice fishing and snowmobiling use. Paddling is therefore a summer and early fall activity. The community of Watson Lake offers full services including motels, campgrounds, RV parks, and restaurants, making it a practical base for paddlers.

For those interested in multi-day river paddling in the broader region, Watson Lake serves as a hub, with outfitters offering fly-in access to rivers such as the Liard, Frances, Tyers, and Highland rivers, several of which have road take-outs near the community. The lake itself, however, is primarily suited to day paddling and casual exploration rather than extended wilderness travel.
