What) The Qu'appelle River Dam is the smaller of the two embankment dams which created Lake Diefenbaker. Construction began in 1959 and was completed in 1967. The dam keeps the flow of water in the Qu'Appelle River relatively constant, as the Qu'Appelle river used to dry up in many places every summer when the snow that fills the South Saskatchewan River from the Rocky Mountains was done melting. The Canadian Pacific Railway crosses the river atop of the dam. The dam is 3100 metres long and 27 metres high. (1)
Where) Highway 19 crosses the Qu'Appelle Valley about 1 km southeast of the dam.
Why) I really wanted to see Gardiner Dam and this one just happened to be pretty much on the way.
