Construction of the tunnel between Coquitlam Lake and Buntzen Lake began in 1902 and finished in 1905, supplying water to powerhouses on Indian Arm, which supplied electricity to Vancouver. [ 2 ] The first Coquitlam Dam , built to raise the water level by 5 feet (1.52 m), was begun in April 1904 and completed in 1905.
The Water Sustainability Act (WSA) is a British Columbia water management law that came into force on February 29, 2016. [1] The WSA allows the government of British Columbia to control groundwater and also surface water in the province. It also includes provisions for restricting water usage during shortages.
It's surface was raised 10 metres; from 46 to 56 metres above sea level. After damming; the lake consisted of six interconnected basins. The lake is also meromictic. It contains fresh water down to approx. 100 metres depth. From that level and further down; only stagnant "old sea water". This water was trapped in the lake; some 10 000 years ago.

The project does not use a full dam and reservoir, rather a 7 m (23 ft) high weir diverts about 250 m 3 /s (8,800 cu ft/s) of water from the Iskut into a 3.3 km (2.1 mi) power tunnel, leading to an underground power station containing turbines and generators. A tailrace tunnel returns the water to the Iskut River downstream of the powerhouse.
In the following table, material data are given with a pressure of 611.7 Pa (equivalent to 0.006117 bar). Up to a temperature of 0.01 °C, the triple point of water, water normally exists as ice, except for supercooled water, for which one data point is tabulated here. At the triple point, ice can exist together with both liquid water and vapor.
The Chilcotin River /tʃɪlˈkoʊtɪn/ [5] located in Southern British Columbia, Canada is a 241 km (150 mi) long tributary of the Fraser River. [6] The name Chilcotin comes from Tŝilhqot’in, meaning "ochre river people," where ochre refers to the mineral used by Tŝilhqot’in Nation and other Indigenous communities as a base for paint or dye.

The development of Sooke Lake as a reservoir was approved in 1910, and construction began in 1912. A concrete dam was constructed and raised the water level 3.7 metres (12 ft). Water was transported to the city of Victoria via the Sooke Flowline, a 44 kilometres (27 mi) concrete aqueduct. The project was completed in 1915.
