These reservoirs can either be on-stream reservoirs , which are located on the original streambed of the downstream river and are filled by creeks , rivers or rainwater that runs off the surrounding forested catchments, or off-stream reservoirs , which receive diverted water from
279-469: A Canadian corporation. Following the successful IPO, CN has recorded impressive gains in its stock price, largely through an aggressive network rationalization and purchase of newer more fuel-efficient locomotives. Numerous branch lines were shed in the late 1990s across Canada, resulting in dozens of independent short line railway companies being established to operate former CN track that had been considered marginal. This network rationalization resulted in

Canada was one of many nations to engage in railway nationalization in order to safeguard critical transportation infrastructure during the First World War . In the early 20th century, many governments were taking a more interventionist role in the economy, foreshadowing the influence of economists like John Maynard Keynes . This political trend, combined with broader geo-political events, made nationalization an appealing choice for Canada. The Winnipeg General Strike of 1919 and allied involvement in

In summary, they consider it a misadaptation to climate change. Proponents of reservoirs or substitution reserves, on the other hand, see them as a solution for sustainable agriculture while waiting for a truly durable agricultural model. Without such reserves, they fear that unsustainable imported irrigation will be inevitable. They believe that these reservoirs should be accompanied by
1209-419: A narrow valley or canyon may cover relatively little vegetation, while one situated on a plain may flood a great deal of vegetation. The site may be cleared of vegetation first or simply flooded. Tropical flooding can produce far more greenhouse gases than in temperate regions. The following table indicates reservoir emissions in milligrams per square meter per day for different bodies of water. Depending upon

CN was then feeding Canadian raw material exports into the U.S. heartland and beyond to Mexico through a strategic alliance with Kansas City Southern Railway (KCS). In 1999, CN and BNSF Railway , the second largest rail system in the U.S., announced their intent to merge, forming a new corporate entity North American Railways , headquartered in Montreal to conform to
1488-522: A possible merger of the two companies. This was later rejected by the Government of Canada, whereupon CPR offered to purchase outright all of CN's lines from Ontario to Nova Scotia, while an unidentified U.S. railroad (rumoured to have been Burlington Northern Railroad ) would purchase CN's lines in western Canada. This too was rejected. In 1995, the entire company including its U.S. subsidiaries reverted to using CN exclusively. The CN Commercialization Act
1581-592: A reservoir is called the "conservation pool". In the United Kingdom, "top water level" describes the reservoir full state, while "fully drawn down" describes the minimum retained volume. There is a wide variety of software for modelling reservoirs, from the specialist Dam Safety Program Management Tools (DSPMT) to the relatively simple WAFLEX , to integrated models like the Water Evaluation And Planning system (WEAP) that place reservoir operations in
1674-450: A river of variable quality or size, bank-side reservoirs may be built to store the water. Such reservoirs are usually formed partly by excavation and partly by building a complete encircling bund or embankment , which may exceed 6 km (4 miles) in circumference. Both the floor of the reservoir and the bund must have an impermeable lining or core: initially these were often made of puddled clay , but this has generally been superseded by

Many coastal reservoirs were constructed in Asia and Europe. Saemanguem in South Korea, Marina Barrage in Singapore, Qingcaosha in China, and Plover Cove in Hong Kong are a few such coastal reservoirs. Where water is pumped or siphoned from
2604-501: Is greater acceptance because all beneficiary users are involved in the implementation of the system. The specific debate about substitution reservoirs is part of a broader discussion related to reservoirs used for agricultural irrigation, regardless of their type, and a certain model of intensive agriculture. Opponents view these reservoirs as a monopolization of resources benefiting only a few, representing an outdated model of productive agriculture. They argue that these reservoirs lead to

A study for the National Institute for Research in the Amazon found that hydroelectric reservoirs release a large pulse of carbon dioxide from decay of trees left standing in the reservoirs, especially during
4743-428: The base of the dam or some distance away. In a flat river valley a reservoir needs to be deep enough to create a head of water at the turbines; and if there are periods of drought the reservoir needs to hold enough water to average out the river's flow throughout the year(s). Run-of-the-river hydro in a steep valley with constant flow needs no reservoir. Some reservoirs generating hydroelectricity use pumped recharge:

The artificial Bhojsagar lake in present-day Madhya Pradesh state of India, constructed in the 11th century, covered 650 square kilometres (250 sq mi). The Kingdom of Kush invented the Hafir , a type of reservoir, during the Meroitic period . 800 ancient and modern hafirs have been registered in
5022-442: The context of system-wide demands and supplies. In many countries large reservoirs are closely regulated to try to prevent or minimize failures of containment. While much of the effort is directed at the dam and its associated structures as the weakest part of the overall structure, the aim of such controls is to prevent an uncontrolled release of water from the reservoir. Reservoir failures can generate huge increases in flow down

To purchase this short section, CN was told by GLT it would have to purchase the entire company. Also included in GLT's portfolio were eight Great Lakes vessels for transporting bulk commodities such as coal and iron ore as well as various port facilities. Following Surface Transportation Board approval for
5208-460: The developed world Naturally occurring lakes receive organic sediments which decay in an anaerobic environment releasing methane and carbon dioxide . The methane released is approximately 8 times more potent as a greenhouse gas than carbon dioxide. As a human-made reservoir fills, existing plants are submerged and during the years it takes for this matter to decay, will give off considerably more greenhouse gases than lakes do. A reservoir in

Such releases are known as compensation water . The units used for measuring reservoir areas and volumes vary from country to country. In most of the world, reservoir areas are expressed in square kilometers; in the United States, acres are commonly used. For volume, either cubic meters or cubic kilometers are widely used, with acre-feet used in
5394-440: The environmental impacts of dams and the reservoirs that they contain. Some impacts, such as the greenhouse gas production associated with concrete manufacture, are relatively easy to estimate. Other impacts on the natural environment and social and cultural effects can be more difficult to assess and to weigh in the balance but identification and quantification of these issues is now commonly required in major construction projects in

Hydropower typically emits 35 to 70 times less greenhouse gases per TWh of electricity than thermal power plants. A decrease in air pollution occurs when a dam is used in place of thermal power generation, since electricity produced from hydroelectric generation does not give rise to any flue gas emissions from fossil fuel combustion (including sulfur dioxide , nitric oxide and carbon monoxide from coal ). Dams can produce
5859-432: The landscape is relatively flat. Other service reservoirs can be storage pools, water tanks or sometimes entirely underground cisterns , especially in more hilly or mountainous country. Modern reserviors will often use geomembrane liners on their base to limit seepage and/or as floating covers to limit evaporation, particularly in arid climates. In the United Kingdom, Thames Water has many underground reservoirs built in

Accurate weather forecasts are essential so that dam operators can correctly plan drawdowns prior to a high rainfall event. Dam operators blamed a faulty weather forecast on the 2010–2011 Queensland floods . Examples of highly managed reservoirs are Burrendong Dam in Australia and Bala Lake ( Llyn Tegid ) in North Wales . Bala Lake
7161-567: The sale of BC Rail. Also contested was the economic stimulus package the government gave cities along the BC Rail route. Some saw it as a buy-off to get the municipalities to cooperate with the lease, though the government asserted the package was intended to promote economic development along the corridor.

As such, their operation consumed
7440-574: The temples of Abu Simbel (which were moved before the construction of the Aswan Dam to create Lake Nasser from the Nile in Egypt ), the relocation of the village of Capel Celyn during the construction of Llyn Celyn , and the relocation of Borgo San Pietro of Petrella Salto during the construction of Lake Salto . Construction of a dammed reservoir will usually require the river to be diverted during part of
7533-414: The transaction shortly thereafter. The EJ&E lines create a bypass around the western side of heavily congested Chicago-area rail hub and its conversion to use for mainline freight traffic is expected to alleviate substantial bottlenecks for both regional and intercontinental rail traffic subject to lengthy delays entering and exiting Chicago freight yards. The purchase of the lightly used EJ&E corridor
7626-456: The transaction, CN completed the purchase of GLT on May 10, 2004. On December 24, 2008, the STB approved CN's purchase for $ 300 million of the principal lines of the Elgin, Joliet & Eastern Railway Company (EJ&E) ( reporting mark EJE) from the U.S. Steel Corporation , originally announced on September 27, 2007.

7812-493: The use of bank-side storage: here water is taken from the River Thames and River Lee into several large Thames-side reservoirs, such as Queen Mary Reservoir that can be seen along the approach to London Heathrow Airport . Service reservoirs store fully treated potable water close to the point of distribution. Many service reservoirs are constructed as water towers , often as elevated structures on concrete pillars where
7905-412: The water, which tends to partition some elements such as manganese and phosphorus into deep, cold anoxic water during the summer months. In the autumn and winter the lake becomes fully mixed again. During drought conditions, it is sometimes necessary to draw down the cold bottom water, and the elevated levels of manganese in particular can cause problems in water treatment plants. In 2005, about 25% of
7998-476: The world's 33,105 large dams (over 15 metres in height) were used for hydroelectricity. The U.S. produces 3% of its electricity from 80,000 dams of all sizes. An initiative is underway to retrofit more dams as a good use of existing infrastructure to provide many smaller communities with a reliable source of energy. A reservoir generating hydroelectricity includes turbines connected to the retained water body by large-diameter pipes. These generating sets may be at
8091-549: The years leading up to 1920: The Canadian National Railway Company then evolved through the following steps: GTR management and shareholders opposed to nationalization took legal action, but after several years of arbitration, the GTR was finally absorbed into the CNR on January 30, 1923.
