What visitors say
Lake Diefenbaker stretches about 225 km across southern Saskatchewan, held back by the Gardiner and Qu'Appelle River dams. It's a long, winding reservoir in the old South Saskatchewan River valley, with coulees and grassy hills running down to the water and wide skies overhead. Visitors talk about the fresh air and the sense of open space.
There's plenty to do. Three provincial parks sit on the lake: Saskatchewan Landing, Douglas and Danielson, along with several regional parks, and together they offer more than a thousand campsites, several beaches and a dozen or so boat launches and marinas. Sailing, paddling, golf and cycling all come up in reviews. One beach area has a volleyball net, benches and a kids' play area, and the Gardiner Dam spillway and interpretive centre at Danielson make a good side trip even when the gates are closed.
It's one of Saskatchewan's best-known fishing lakes. Provincial lake information lists walleye, northern pike, sauger, yellow perch, burbot, and rainbow and lake trout, and the lake has produced record rainbow trout and burbot. Lake sturgeon are catch-and-release only. Guides and outfitters work the lake, and one reviewer caught their first fish here as a child.
Not every beach suits everyone. One visitor found the shoreline rocky and bird feathers blowing around, and wouldn't come back for a beach day, so pick your access point with care. Wind can build quickly on a lake this size, which matters in small boats. Provincial park entry permits apply in the provincial parks, and a reviewer asks visitors to pack out their garbage.
