Fishing Lake Diefenbaker: the full guide
Lake Diefenbaker
Lake Diefenbaker is the reservoir formed by the Gardiner and Qu’Appelle River dams on the South Saskatchewan River, a long, winding lake of more than two hundred kilometres through the prairie coulees of southern Saskatchewan, between Saskatoon, Moose Jaw and Swift Current. It is the province’s best-known open-water fishing lake, with provincial parks at Danielson, Douglas and Saskatchewan Landing. The Water Survey of Canada gauge at Gardiner Dam supplies the lake level and the 30-day chart on this page.
Species and seasons
Walleye, sauger and northern pike are the main fish, with yellow perch and burbot; the lake is also known for large rainbow trout, some of them from the fish farms in the reservoir. The Saskatchewan anglers’ guide sets the lake’s seasons and limits.
Where to fish it
The lake is fished from boats out of the provincial parks and the marinas at Elbow, Riverhurst and Saskatchewan Landing, and from the shore at the parks; in winter, the bays are ice-fished. The lake is long and exposed, and the wind can build large waves.
Planning a visit
Elbow and the Douglas and Danielson parks are about ninety minutes from Saskatoon; Saskatchewan Landing is near Swift Current. The Riverhurst ferry crosses the lake in open water. The lake is named after John Diefenbaker, the prime minister from Saskatchewan.
The water through the year
The reservoir level rises with the spring runoff from the Rockies and falls through the year as water is released downstream; the lake freezes in winter.
Reading this report here
The gauge at Gardiner Dam shows the reservoir level and the chart the last 30 days; changes in level move the fish along the shore. Pressure and sky build the score.
Licence, access and rules
A Saskatchewan angling licence and, for anglers 16 to 64, the Fisheries Habitat Certificate are needed; residents under 16 and Saskatchewan residents 65 and over are exempt. The rules are linked below, and our Saskatchewan licence page has the fees.
