Metro Vancouver Watersheds
The Metro Vancouver watersheds, also known as the Greater Vancouver watersheds, supply potable water to approximately 2.7 million residents in the Lower Mainland of British Columbia. They provide tap water to a land area covering more than 2,600 km², including Vancouver, Langley and Richmond. Metro Vancouver serves a total of 21 member municipalities, one electoral district, and one treaty First Nation. From west to east, the watersheds are the Capilano (19,545 hectares), the Seymour (12,375 hectares), and the Coquitlam (20,461 hectares). They are located in the North Shore Mountains and Coquitlam Mountain, respectively. Each watershed possesses a reservoir for water storage purposes, under the control of Metro Vancouver. The reservoirs are supplied by about 3.5 metres of rain and 4.5 metres of snowpack annually. Two additional off- catchment areas (Lower Seymour Conservation Reserve and Or Creek watershed) under control of Metro Vancouver contribute to the water supply.http: ...

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capilano River
The Capilano River flows from north to south through the Coast Mountains on Vancouver's North Shore between West Vancouver and North Vancouver (district municipality) and empties into Burrard Inlet, opposite Stanley Park. The river is one of three primary sources of drinking water for residents of Greater Vancouver, and flows through the Capilano watershed. The Cleveland Dam, built in 1954, impounds a reservoir for this purpose. The entire area of the reservoir and watershed area upstream of the dam is closed to the public to ensure the quality of the drinking water. Prior to construction of the Cleveland Dam, the Capilano River deposited large amounts of sediment into Burrard Inlet. A dredge was needed to remove this sediment build-up in order to keep Burrard Inlet open for ship traffic. The Capilano has a historic salmon run which was impacted by the dam construction. In 1971 the Capilano Fish hatchery was opened. It was built 1/2 kilometre (km) downstream of the dam to ensur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coquitlam Lake
Coquitlam Lake is a reservoir located just north of Coquitlam, British Columbia. It is one of the three main water sources for Metro Vancouver, and part of the Coquitlam watershed. It is also a part of BC Hydro's power generation system. A tunnel directs water from the lake to nearby Buntzen Lake, and from there to a pair of power stations. History 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.Will KoopCoquitlam Watershed History Retrieved on 22 February 2009 The first Coquitlam Dam, built to raise the water level by , was begun in April 1904 and completed in 1905. It was built to protect the water supply to the powerhouses, and also supplied water to New Westminster. By 1906 the original dam was discovered to be leaking, and while repairs were made the leak continued through 1908, until the current dam was completed in 1914. There is a ...

Burnaby
Burnaby is a city in the Lower Mainland region of British Columbia, Canada. Located in the centre of the Burrard Peninsula, it neighbours the City of Vancouver to the west, the District of North Vancouver across the confluence of the Burrard Inlet with its Indian Arm to the north, Port Moody and Coquitlam to the east, New Westminster and Surrey across the Fraser River to the southeast, and Richmond on the Lulu Island to the southwest. Burnaby was incorporated in 1892 and achieved its city status in 1992. A member municipality of Metro Vancouver, it is British Columbia's third-largest city by population (after Vancouver and Surrey), and is the seat of Metro Vancouver's regional district government. 25% of Burnaby's land is designated as parks and open spaces, one of the highest in North America.

Second Narrows Bridge
The Second Narrows Rail Bridge is a vertical-lift railway bridge that crosses the Burrard Inlet and connects Vancouver with the North Shore. The bridge's south end connects directly to the Thornton Tunnel, which connects it to the main Canadian rail network. As the name suggests, it is located at the second narrowing of the Burrard Inlet. History Background During the Klondike Gold Rush, there were schemes to build a railway from Vancouver to the Dawson gold fields. The first stage in this would be to bridge Burrard Inlet and then build a railway north. John Hendry floated the Vancouver, Westminster, and Yukon Railway which built a line from Ladner to New Westminster and then to Vancouver via Burnaby Lake. This line was paired with the Great Northern Railway who also wanted trackage into Vancouver. In the process, various other railroads all became involved in the bridging scheme: the Canadian Northern Railway, Milwaukee Road, and the Pacific Great Eastern Railw ...

North Vancouver (district Municipality)
The District of North Vancouver is a district municipality in British Columbia, Canada, and is part of Metro Vancouver. It surrounds the City of North Vancouver on three sides. As of 2016, the District stands as the second wealthiest city in Canada, with neighbouring West Vancouver the richest. The municipality is largely characterized as being a relatively quiet, affluent suburban hub home to many middle and upper-middle-class families. Homes in the District generally range from mid-sized family bungalows to very large luxury houses. A number of dense multi-family and mixed-use developments have popped up across the district in recent years; however, the District remains a primarily suburban municipality. The District is served by the Royal Canadian Mounted Police, British Columbia Ambulance Service, and the District of North Vancouver Fire Department. History For thousands of years, the Indigenous Squamish and their kin Tsleil-Waututh, of the Coast Salish, resided in the ...

Stave (wood)
] A stave is a narrow length of wood with a slightly bevelled edge to form the sides of barrels, tanks, tubs, vats and pipelines, originally handmade by coopers. They have been used in the construction of large holding tanks and penstocks at hydro power developments. They are also used in the construction of certain musical instruments with rounded bodies or backs. See also *Rubicon Hydroelectric Scheme, which has wood stave penstocks on operating power stations *Lake Margaret Power Station The Lake Margaret Power Stations comprise two hydroelectric power stations located in Western Tasmania, Australia.

Lumber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly ...

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date bac ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Seymour River (Burrard Inlet)
The Seymour River is a river in North Vancouver, British Columbia which is notable for being several degrees warmer than other streams and lakes in the area. This is due to it being fed from a large reservoir backed up behind a dam from which a constant flow of water is released. The upper portion of the river and the reservoir are part of the Seymour watershed, controlled by Metro Vancouver. The Seymour River has been the main water supply for North Vancouver since 1907. The first intake was built in 1907 and the first Seymour Dam was constructed in 1927. The present day Seymour Falls Dam Seymour may refer to: Places Australia *Seymour, Victoria, a township *Electoral district of Seymour, a former electoral district in Victoria *Rural City of Seymour, a former local government area in Victoria *Seymour, Tasmania, a locality ... was constructed 1961.
