Terzaghi Dam
Terzaghi Dam is the key diversion dam in BC Hydro's Bridge River Power Project. It forms the project's largest reservoir, Carpenter Lake west of Lillooet. Originally known as the Mission Dam, it was renamed Terzaghi Dam in 1965 to honor Karl von Terzaghi, the civil engineer who founded the science of soil mechanics. It is located about 30 km up the Bridge River from its confluence with the Fraser. It stands at the head of the Big Canyon of the Bridge River, completely blocking the river, which is diverted through two tunnels through Mission Mountain to a pair of powerhouses on Seton Lake. The difference in elevation between Carpenter Lake, the reservoir formed by Terzaghi Dam, and the two powerhouses on Seton Lake is c. 410 m, which in combination with the flow of the entire Bridge River generates 480 megawatts in electrical power. Completed in the 1950s, it was the expansion of a concept first launched in the 1920s by the Bridge River Power Development Co. but abandoned due ...

Karl Von Terzaghi
Karl von Terzaghi (October 2, 1883 – October 25, 1963) was an Austrians, Austrian Mechanical Engineer, mechanical engineer, geotechnical engineer, and geologist known as the "father of soil mechanics and geotechnical engineering". Early life In 1883, he was born the first child of Army Lieutenant-Colonel Anton von Terzaghi, of Italian origin, and Amalia Eberle in Prague, in what is now the Czech Republic. Upon his father's retirement from the army, the family moved to Graz, Austria. At 10, Terzaghi was sent to a military boarding school, where he developed an interest in astronomy and geography. At age fourteen, Terzaghi entered a different military school, in Hranice (Přerov District), Hranice, the Crown of Bohemia. He was an excellent student, especially in geometry and mathematics, and graduated with honors at 17. In 1900, Terzaghi entered the Technical University Graz, Technical University in Graz to study mechanical engineering, where he also developed an interest in the ...

Megawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). ...

Dams In British Columbia
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Shalalth, British Columbia
Shalalth and South Shalalth are unincorporated communities on the northern shore near the western end of Seton Lake in the Squamish-Lillooet region of southwestern British Columbia. The localities are by road about northwest of Lillooet, but only by rail. First Nations The word Shalalth (pronounced Sha-LATH and spelled Tsal’álh in St'at'imcets, the Lillooet language) means simply "lake" or, particularly, ''the'' lake, meaning Seton Lake. Indigenous peoples form the majority of the population in the valley and in the Shalalth environs, which is one of the main communities of the Seton Lake First Nation Band of the St'at'imc (Lillooet) Nation. A First Nations school, small timber mill, and various small businesses operate. In 1990s, the Seton Lake First Nation built a new residential subdivision named Ohin, further east than the traditional Shalalth rancherie area (beginning at the base of the Mission Mountain Road to a few coves east). The name Ohin, pronounced ''OO(kh)wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Minto City, British Columbia
Minto City, often called just Minto, sometimes Minto Mines, Minto Mine, Skumakum, or "land of plenty", was a gold mining town in the Bridge River Valley of British Columbia from 1930 to 1936, located at the confluence of that river with Gun Creek (British Columbia), Gun Creek, one of its larger tributaries. The mine prospect was never much successful although a model townsite was built by promoter "Big Bill" Davidson, who imported soil to build a specially-built rodeo ground and baseball diamond on the rocky site. The larger mine of Bralorne was nearby. The mine shut down in 1936 due to productivity issues, but restarted in 1940. The valley has since been significantly altered when most of the vestiges of the town were inundated by the waters of the Carpenter Lake reservoir following completion of the Bridge River Power Project. In 1941, around two dozens of Japanese Canadian families were relocated to Minto Mine, and ordered to live in the empty miners' houses due to the impacts of ...

Post-war Boom
A post-war or postwar period is the interval immediately following the end of a war. The term usually refers to a varying period of time after World War II, which ended in 1945. A post-war period can become an interwar period or interbellum, when a war between the same parties resumes at a later date (such as the period between World War I and World War II). By contrast, a post-war period marks the cessation of armed conflict entirely. Post-World War II in the United States Chronology of the post–World War II era The term "post-war" can have different meanings in different countries and refer to a period determined by local considerations based on the effect of the war there. Considering the post-war era as equivalent to the Cold War era, post-war sometimes includes the 1980s, putting the end at 26 December 1991, with the dissolution of the Soviet Union. The 1990s and the 21st century are sometimes described as part of the post-war era, but the more specific designation " ...

British Columbia Electric Railway
The British Columbia Electric Railway (BCER) was an historic railway which operated in southwestern British Columbia, Canada. Originally the parent company for, and later a division of, BC Electric Company (now BC Hydro), the BCER assumed control of existing streetcar and interurban lines in southwestern British Columbia in 1897, and operated the electric railway systems in the region until the last interurban service was discontinued in 1958. During and after the streetcar era, BC Electric also ran bus and trolleybus systems in Greater Vancouver and bus service in Greater Victoria; these systems subsequently became part of BC Transit, and the routes in Greater Vancouver eventually came under the control of TransLink. Trolley buses still run in the City of Vancouver with one line extending into Burnaby. History Streetcar and interurban services were inaugurated in southwestern British Columbia between 1890 and 1891, operated by the following companies: * National Electric ...

Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Weimar Republic, Germany. The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". Much of the profit generated by the boom was invested in speculation, such as on the stock market, contributing to growing Wealth inequality in the United States, wealth inequality. Banks were subject to laissez-faire, minimal regulation, resulting in loose lending and wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Seton Lake
Seton Lake is a lake in the Squamish-Lillooet region of southwestern British Columbia. On the northeast side is Mission Ridge. On the southwest is the Cayoosh Range. By road, the eastern end is about southwest of Lillooet. Name origin In 1827, Francis Ermatinger of the Hudson's Bay Company (HBC), the first European explorer, referred to the Seton and Anderson lakes as the first and second Peseline Lake (various spellings). In 1846, Alexander Caulfield Anderson paddled along the lakes when seeking a new HBC fur brigade route from Fort Alexandria. In 1858, Governor James Douglas commissioned Anderson to establish a route to the goldfields during the Fraser Canyon Gold Rush. The governor encouraged Anderson to name the lakes after his family. Anderson's cousin Colonel Alexander Seton of the 74th Regiment, who was in command of the troops on board HMS Birkenhead, which sank in 1852, was noted for his exemplary conduct in the moment and was among those who drowned.

Bridge River Power Project
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. Discovery and original development The potential for the project was first observed in 1912 by Geoffrey Downton, a land surveyor, visiting the goldfield towns in the area who noticed the short horizontal distance between the flow of the Bridge River, just above its impressive canyon, and the much-lower Seton Lake. It was fifteen years before this observation was put to task, and not until 1927 that a private company first bored a tunnel through Mission Ridge (also known as Mission Mountain), which separates the basins of the Bridge and Seton systems. This tunnel was completed in 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
