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.
The Lake is impounded by two embankment dams; the 28-metre-high Canyon Dam is near the southern end of the reservoir and blocks the main outlet of the river in a north-northwestern direction, while the secondary 13-metre-high Three Sisters Dam at the northern end of the reservoir provides the outlet for the diverted water way and contains a small 3 MW powerhouse. The two dams and the lake were created in 1951 as part of the Spray Hydro Electric Project. From the Three Sisters Dam the water is diverted into a secondary reservoir known as the Goat Pond which directs the water into a 6-kilometre-long canal which includes an 800-metre tunnel though the shoulder of Ha Ling Peak. From there it enters White Man Pond before being funnelled into a penstock to the main Spray Powerhouse at Grassi Lakes with a generating capacity of 112 MW. The water continues to another shorter penstock leading to the Rundle Powerhouse where an additional 50 MW of generation is available. From there water is released into the Bow River. The four dams and three power stations are owned and operated by TransAlta. The Spray River Project contains a total of five dams and three powerhouses with a total generating capacity of 165 MW, the Spray River diversion making it the highest-yielding conventional (non-pumped-storage) hydroelectric facility in the province. [1]
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.
The lake is fed by the following waterways, in anticlockwise order starting at the Canyon Dam: [2]
The lake lies completely inside the north-western corner of the Spray Valley Provincial Park in the recreational area of Kananaskis Country. For more than half of the lake, from the Three Sisters Dam in the north to Mount Buller in the south, the western border of the Bow Valley Wildland Provincial Park runs along the Smith-Dorrien Trail, close to the eastern shore.
For the whole length of the lake, the eastern border of Banff National Park lies within five kilometers of the western shore. In the north, the border of the national park runs along the crest of the Goat Range. Near the southern end of the lake, the border is close to the shore. [2]
An assortment of recreational areas are established on both shores.
The western shore is paralleled by hiking trails, and picnic sites and campgrounds are set up on both sides of the lake.
Kananaskis Country is a multi-use area west of Calgary, Alberta, Canada in the foothills and front ranges of the Canadian Rockies. The area is named for the Kananaskis River, which was named by John Palliser in 1858 after a Cree acquaintance. Covering an area of approximately 4,000 km2 (1,500 sq mi), Kananaskis Country was formed by the Alberta Government in 1978 to provide an assortment of land uses and designations. Land uses include resource extraction activities, recreation, power generation, and residential communities. Land designations include public land and protected areas.
Lake Minnewanka is a glacial lake in the eastern area of Banff National Park in Canada, about five kilometres northeast of the Banff townsite. The lake is 21 km (13 mi) long and 142 m (466 ft) deep, making it the 2nd longest lake in the mountain parks of the Canadian Rockies.
Peter Lougheed Provincial Park is in Kananaskis Country about 90 kilometres (56 mi) west of Calgary, along the Kananaskis Trail in Alberta, Canada.
The Bridge River Power Project is a hydroelectric power development in the Canadian province of British Columbia, located in the Lillooet Country between Whistler and Lillooet. It harnesses the power of the Bridge River, a tributary of the Fraser, by diverting it through a mountainside to the separate drainage basin of Seton Lake, utilizing a system of three dams, four powerhouses and a canal.
Lake Almanor is a large reservoir in northwestern Plumas County, northeastern California, United States. The reservoir has a capacity of 1,308,000 acre-feet (1.613×109 m3) and a maximum depth of about 90 feet (27 meters). The surface area is 43.75 square miles (11,331.2 hectares). It is formed by Canyon Dam on the North Fork of the Feather River, as well as Benner and Last Chance Creeks, Hamilton Branch, and various natural springs.
Whiskeytown Lake is a reservoir in Shasta County in northwestern California, United States, about 8 miles (13 km) west of Redding. The lake is in the Whiskeytown Unit of the Whiskeytown-Shasta-Trinity National Recreation Area.
Spray Valley Provincial Park is a provincial park located east of the Rocky Mountains, along the Spray River in western Alberta, Canada.
The Spray River is a tributary of the Bow River in western Alberta, Canada.
The Kananaskis River is a mountain river in western Alberta, Canada. It is a tributary of the Bow River, crossing the length of Kananaskis Country.
Barrier Lake is a man-made reservoir at the north end of Kananaskis Country in Alberta, Canada.
Lower Kananaskis Lake is a natural lake that was turned into a reservoir in Kananaskis Country in Alberta, Canada.
Alouette Lake, originally Lillooet Lake and not to be confused with the lake of that name farther north, is a lake and reservoir in Maple Ridge, British Columbia, Canada. It is at the southeastern foot of the mountain group known as the Golden Ears and is about 16 km in length on a northeast–southwest axis. It, and the Alouette River, were renamed in 1914 to avoid confusion with the larger river and lake farther north, with "Alouette", the French word for "lark", being chosen as being melodious and reminiscent of the original name in tone.
Mammoth Pool Dam is a hydroelectric dam located on the San Joaquin River in the southern Sierra Nevada mountain range of California, about 45 miles (72 km) northeast of Fresno. It forms Mammoth Pool Reservoir and lies within the Sierra National Forest. The dam and reservoir were named after a large natural pool in the river that was once located above the present dam site.
Lake Shannon is a long, narrow reservoir on the Baker River in Skagit County, Washington in the United States. Formed in the 1920s by the construction of an arch dam just above the town of Concrete, the lake is approximately 7.5 miles (12 km) long and averages 0.6 miles (1 km) wide when full. Located just outside the western boundary of North Cascades National Park, Lake Shannon serves as the lower reservoir for Puget Sound Energy's Baker River Hydroelectric Project.
Ruskin Dam is a concrete gravity dam on the Stave River in Ruskin, British Columbia, Canada. The dam was completed in 1930 for the primary purpose of hydroelectric power generation. The dam created Hayward Lake, which supplies water to a 105 MW powerhouse and flooded the Stave's former lower canyon, which ended in a small waterfall approximately where the dam is today.
The Yuba–Bear Hydroelectric Project is a complex hydroelectric scheme in the northern Sierra Nevada in California, tapping the upper Yuba River and Bear River drainage basins. The project area encompasses approximately 400 square miles (1,000 km2) in Nevada, Placer, and Sierra Counties. Owned by the Nevada Irrigation District, it consists of 16 storage dams plus numerous diversion and regulating dams, and four generating stations producing 425 million kilowatt hours of electricity each year. The Yuba–Bear Hydroelectric Project consists of the Bowman development, Dutch Flat No. 2 development, Chicago Park development, and Rollins development.
The Upper North Fork Feather River Project is a hydroelectric scheme in the Sierra Nevada of California, within Lassen and Plumas Counties. The project consists of three dams, five power plants, and multiple conduits and tunnels in the headwaters of the North Fork Feather River, a major tributary of the Feather—Sacramento River systems. The total installed capacity is 362.3 megawatts (MW), producing an annual average of 1,171.9 gigawatt hours (GWh). The project is also contracted for the delivery of irrigation water between March 31 and October 31 of each year. The project is owned and operated by Pacific Gas and Electric Company.
