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 ...

Coquitlam
Coquitlam ( ) is a city in the Lower Mainland of British Columbia, Canada. Mainly suburban, Coquitlam is the List of cities in British Columbia, sixth-largest city in the province, with a population of 148,625 in 2021, and one of the 21 municipalities comprising Metro Vancouver. The mayor is Richard Stewart. Simon Fraser (explorer), Simon Fraser explored the region in 1808, encountering the Indigenous Coast Salish peoples. Europeans started settling in the 1860s. Fraser Mills, a lumber mill on the north bank of the Fraser River was constructed in 1889, and by 1908 there were 20 houses, a store, post office, hospital, office block, barber shop, pool hall, and a Gurdwara, Sikh temple. History The Coast Salish people were the first to live in this area, and archaeology confirms continuous occupation of the territory for at least 9,000 years. The name ''Kwikwetlem First Nation, Kwikwetlem'' is said to be derived from a Coast Salish term "kʷikʷəƛ̓əm" meaning "red fish up th ...

Indian Arm
Indian Arm ( hur, səl̓ilw̓ət) is a steep-sided glacial fjord adjacent to the city of Vancouver in southwestern British Columbia. Formed during the last Ice Age, it extends due north from Burrard Inlet, between the communities of Belcarra (to the east) and the District of North Vancouver (to the west), then on into mountainous wilderness. Burrard Inlet and the opening of Indian Arm was mapped by Captain George Vancouver and fully explored days later by Dionisio Alcalá Galiano in June 1792. Geography Indian Arm is a salt-water fjord that extends about north from Burrard Inlet. There are no crossings, and road access is limited to the communities on the southern portion of the arm. The steep mountain slopes are so impassable that most have seen no development, despite the proximity to a major city. Indian River, marked by a small dock at the north end of the arm, can be reached by boat from the Vancouver area or by a logging road from Squamish. Scenery and attractions ...

Lakes Of The Lower Mainland
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Coquitlam
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Little Ice Age
The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region. It was not a true ice age of global extent. The term was introduced into scientific literature by François E. Matthes in 1939. Matthes described glaciers in the Sierra Nevada of California that he believed could not have survived the hypsithermal; his usage of "Little Ice Age" has been superseded by "Neoglaciation". The period has been conventionally defined as extending from the 16th to the 19th centuries, (noted in Grove 2004:4). but some experts prefer an alternative timespan from about 1300 to about 1850. The NASA Earth Observatory notes three particularly cold intervals. One began about 1650, another about 1770, and the last in 1850, all of which were separated by intervals of slight warming. The Intergovernmental Panel on Climate Change Third Assessment Report considered that the timing and the areas affected by the Little Ice Age suggested largely independent ...

New Westminster
New Westminster (colloquially known as New West) is a city in the Lower Mainland region of British Columbia, Canada, and a member municipality of the Metro Vancouver Regional District. It was founded by Major-General Richard Moody as the capital of the Colony of British Columbia in 1858 and continued in that role until the Mainland and Island colonies were merged in 1866. It was the British Columbia Mainland's largest city from that year until it was passed in population by Vancouver during the first decade of the 20th century. It is located on the banks of the Fraser River as it turns southwest towards its estuary, on the southwest side of the Burrard Peninsula and roughly at the centre of the Greater Vancouver region. History The area now known as New Westminster was originally inhabited by Kwantlen First Nation. The discovery of gold in BC and the arrival of gold seekers from the south prompted fear amongst the settlers that Americans may invade to take over this land. R ...

Coquitlam Dam
Coquitlam Dam is a hydraulic fill embankment dam on the Coquitlam River in the city of Coquitlam, British Columbia. Although it has no powerhouse of its own, its waters divert to Buntzen Lake, making it part of BC Hydro's electrical generation infrastructure. It is also one of the main reservoirs for the Greater Vancouver Water District. BC Hydro has released a new document in March 2018 that addresses emergency preparedness and outlines the areas effected should the dam fail as a result of an extreme earthquake event. History The first Coquitlam Dam, built to raise the water level of Coquitlam Lake by five feet, was begun in April 1904, and completed in 1905. It was built to protect the water supply to powerhouses on Indian Arm, via a tunnel to Buntzen Lake, and also supplied water to New Westminster New Westminster (colloquially known as New West) is a city in the Lower Mainland region of British Columbia, Canada, and a member municipality of the Metro Vancouver Reg ...

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: ...
