The Spray River is an approximately 40 miles long right tributary of the Bow River in the southwest of the Canadian province of Alberta .
River course
The Spray River has its source in the Canadian Rockies on the North American continental divide . The headwaters are located on the northeast flank of Mount King Albert ( 2972 m ). The Spray River initially flows 18 km to the north and flows into the western end of the 19.9 km² Spray Lakes Reservoir located at an altitude of 1700 m . The reservoir was created in 1950 after the completion of the Canyon Dam on the Spray River and Three Sister Dam on its tributary Goat Creek . Much of the water is now fed from the reservoir to a hydropower station (112 MW capacity) near Canmore , from where it flows directly into the Bow River. The reservoir is within Spray Valley Provincial Park . The Spray River continues northward below Canyon Dam , flanked by the Sundance Range to the west and the Goat Range to the east . 9 km above the mouth, Goat Creek meets the Spray River from the right. The Spray River finally flows into the Bow River at Banff .
Hydrology
The catchment area of the Spray River covers 751 km². The mean discharge between 1911 and 1948 was 14.2 m³ / s. After the completion of the Spray Lakes Reservoir and the connected hydropower plant in 1951, the annual mean discharge was reduced to 3.2 m³ / s.
