In 1887, the Capilano River was selected as the source of water supply for the City of Vancouver.An intake pipe was constructed 11 kilometres (6.8 mi) upstream of the mouth of the river, and a pipeline carried this water across the First Narrows of Burrard Inlet and into the City of Vancouver.
The resulting increase in the water supply made it possible to fill four cisterns, ranging in size from 25,000 to 60,000 imperial gallons (114,000 to 276,000 L) to provide a reserve of water for fire protection. [6] Coe and Martin formed the Spring Ridge Water Works Company in 1864, serving the city until 1875.
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 department was renamed the "Department of Lands, Forests, and Water Resources" in 1962 following its reorganization into its three namesake branches: the B.C. Lands Service, B.C. Forest Service, and B.C. Water Resources Service. It retained the same responsibilities as its predecessor until the disestablishment of the department in 1975. [6]
Beatty Creek is a tributary of the Tahltan River in northwest part of the province of British Columbia, Canada.It flows generally south about 62 km (39 mi) [4] to join the Tahltan River a few kilometres downstream from the Little Tahltan River confluence. [1]
The river flooded parts of Merritt due to very high water in 1995 [53] and an ice jam in 2005. [54] During the 2021 Pacific Northwest floods, the river damaged the Merritt wastewater treatment plant, about 600 residences, and several commercial properties. The entire community of 7,100 residents had to be evacuated. [55]
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.
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.
