Jones Falls Dam
Jones Falls Dam is a dam on the Rideau Canal located in Rideau Lakes, Leeds and Grenville United Counties, Ontario, Canada, that was built between 1828 and 1831 to tame the mile-long series of rapids and falls that flowed from Sand Lake and into the White Fish River (now drowned). History The dam, designed by the British Royal Engineers under the direction of Lt. Colonel John By, was built by crews working for contractor John Redpath. It was built by hand, with the assistance of a few draft animals. When completed in late 1831, the Jones Falls dam was the highest dam in North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere.

Rideau Canal
The Rideau Canal, also known unofficially as the Rideau Waterway, connects Canada's capital city of Ottawa, Ontario, to Lake Ontario and the Saint Lawrence River at Kingston. It is 202 kilometres long. The name ''Rideau'', French for "curtain", is derived from the curtain-like appearance of the Rideau River's twin waterfalls where they join the Ottawa River. The canal system uses sections of two rivers, the Rideau and the Cataraqui, as well as several lakes. Parks Canada operates the Rideau Canal. The canal was opened in 1832 as a precaution in case of war with the United States. It remains in use today primarily for pleasure boating, with most of its original structures intact. The locks on the system open for navigation in mid-May and close in mid-October. It is the oldest continuously operated canal system in North America. In 2007 it was registered as a UNESCO World Heritage Site. History Plan After the War of 1812, information was received about the United States' ...

Ontario ( ; ) is one of the thirteen provinces and territories of Canada.Ontario is located in the geographic eastern half of Canada, but it has historically and politically been considered to be part of Central Canada. Located in Central Canada, it is Canada's most populous province, with 38.3 percent of the country's population, and is the second-largest province by total area (after Quebec). Ontario is Canada's fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto, which is Ontario's provincial capital. Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east and northeast, and to the south by the U.S. states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania, and New York.

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

John Redpath
John Redpath (1796 – March 5, 1869) was a Scots-Quebecer businessman and philanthropist who helped pioneer the industrial movement that made Montreal, Quebec the largest and most prosperous city in Canada. Early years In 1796, John Redpath was born at Earlston, Berwickshire. According to surviving records, he was the son of Peter Redpath, a farm worker, and his second wife Elizabeth Pringle, from neighbouring Gordon, Berwickshire. Redpath was born during the period of the Lowland Clearances that created economic hardship and dislocation for many Scottish families. As such, after gaining valuable experience as a stonemason with George Drummond in Edinburgh, the twenty-year-old Redpath emigrated to Canada. In 1816, with limited funds for ship passage, the nearly penniless Redpath disembarked at Quebec City before walking barefoot to Montreal, Quebec. Once there, he used the trade he had learnt back in Scotland to gain him employment in the construction industry, working ...

Sand Lake (Leeds And Grenville United Counties, Ontario)
Sand Lake is a lake on the Rideau Canal, located in the Township of Rideau Lakes, Ontario, Canada, in the ward of South Crosby. It is in surface area, with a maximum depth of and a shore length of History San Lake is the southernmost of the original pre-Rideau Canal lakes in this area. To the north, water from Opinicon Lake flowed south through a small river to Sand Lake. At the southern outlet of Sand Lake, the long Jones Falls Rapids flowed into the White Fish River, which then flowed through Morton Bay on its way to Lower Beverley Lake and from there via the Gananoque River to Gananoque, Ontario. It was part of a native travel route that led from the Ottawa River, up the Rideau River, through the Rideau Lakes, and then to the St. Lawrence River at Gananoque. The lake was a bit smaller, and lower, than it is today. The name, Sand Lake, first appears on an 1816 map of the Rideau waterway drawn by Lieutenant Joshua Jebb, Royal Engineer. In about 1820, settler Walter Da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Ontario
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 earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arch Dams
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...
