Spray Lakes Reservoir is a reservoir in Alberta, Canada. The Spray Lakes were a string of lakes formed along the Spray River, a tributary of the Bow River. With the damming of the river, the lakes were united in the Spray Lakes Reservoir. It lies between the Goat Range and the Three Sisters ridge, at an elevation of 1,720 metres (5,640 ft).The lake is followed by Highway 742 (Smith-Dorrien Trail) in the northern part. As a result of the diversion the river's original water course downstream of the Canyon Dam is nothing more than trickle for most of the year.
