Danielson Provincial Park is located at the northern end of Lake Diefenbaker in the southern part of the Canadian province of Saskatchewan. The park surrounds the Gardiner Dam, which was built in 1967 and is among the largest embankment dams in Canada and the world. The South Saskatchewan River flows north beyond the park, towards Outlook and Saskatoon. Saskatchewan Highways 44, 45, and 219 provide access to the park. SaskPower's Coteau Creek Hydroelectric Station is located near the park.
