Lake Chelan Dam
Lake Chelan Dam officially known as the Lake Chelan Hydroelectric Project is located approximately 32 miles (51 km) north of the city of Wenatchee in Chelan County. The dam is located at the lower or southeasterly end of long Lake Chelan, and is within the limits of the city of Chelan. The powerhouse is located near the community of Chelan Falls. The reservoir has of usable water storage. The 10-year average generation for the Project is 365,000 megawatt hours. History The Chelan River has a history of dam development for navigation, power generation, and water supply. In 1894, floodwaters pushed the lake level 11 feet (3 m) above the old (pre-project) high-water mark. The future spillway segment of the dam was calculated and built to avoid a recurrence of such flooding. The dam was built to raise the level of Lake Chelan and completed in 1892. It was constructed to provide water for south Chelan real estate and navigation to the city of Chelan. It washed out d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelan, Washington
Chelan ( ) is a city in Chelan County, Washington, United States. The estimated population was 3,850 at the 2010 census with a margin of error of ±15. The population was 4,222 at 2018 Estimate from Office of Financial Management. It lies on the southeast tip of Lake Chelan, where the lake flows into the Chelan River. Chelan is part of the Wenatchee−East Wenatchee Metropolitan Statistical Area. History The original inhabitants of the Chelan area were the Chelan, a tribe of Salish-speaking Native Americans. Relatively little is known about the culture and lifestyle of the early Chelan, as the tribe had adopted the dress, beadwork, and equestrian culture of the Plains Indians by the time of European contact. Infectious diseases including smallpox and measles arrived sometime prior to white settlement of the area, and had killed an estimated 90% of the Indians by the time explorer David Thompson arrived on the Columbia in 1811. Until this point tribal decision-making had b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Load Rejection
Load rejection in an electric power system is the condition in which there is a sudden load loss in the system which causes the generating equipment to be over-frequency. A load rejection test is part of commissioning for power systems to confirm that the system can withstand a sudden loss of load and return to normal operating conditions using its governor. Load banks are normally used for these tests. See also * Power outage A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user.

Energy Infrastructure Completed In 1927
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Dams Completed In 1927
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.

Hydroelectric Power Plants In Washington (state)
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Buildings And Structures In Chelan County, Washington
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Island Dam
Rock Island Dam is a hydroelectric dam on the Columbia River, in the U.S. state of Washington. Chelan County Public Utility District's ''Rock Island Dam and Hydro Project'' was the first dam to span the Columbia, having been built from 1929 to 1933. It is located near the geographical center of Washington, about 12 miles (19 km) downstream from the city of Wenatchee. By river, the dam is 235 miles (378 km) south of the Canada–US border and 453 miles (729 km) above the mouth of the river at Astoria, Oregon. The dam's reservoir is called Rock Island Pool.http://pubs.usgs.gov/wdr/2005/wdr-wa-05-1/pdf/wa00103ADR2005_Figure56.pdf Overview Rock Island Dam is constructed on Columbia River basalt similar to that which is exposed on the cliffs near the dam. These columnar basalts were formed from lava flows during the mid- to late-Miocene Epoch, some 14 to 16 million years ago. The rock is strong and durable and provides a very stable foundation for the structure. Columb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocky Reach Dam
Rocky Reach Dam is a run-of-the-river hydroelectric dam in the U.S. state of Washington owned and operated by Chelan County Public Utility District. It has 11 generators rated in total 1300 MW. The project is on the Columbia River in north central Washington state about upstream from the city of Wenatchee. The dam is above the mouth of the Columbia. The reservoir impounded by the dam is Lake Entiat. The project provides energy for more than 7 million people throughout the Pacific Northwest. Rocky Reach is nationally recognized for efforts to protect the environment. A first-of-its-kind juvenile fish bypass system was completed in 2003 to help young salmon and steelhead on their way to the ocean. A major powerhouse upgrade started in 1995 includes new turbines that are more fish friendly.McKee, C, and G.

List Of Dams In The Columbia River Watershed
There are more than 60 dams in the Columbia River watershed in the United States and Canada. Tributaries of the Columbia River and their dammed tributaries, as well as the main stem itself, each have their own list below. The dams are listed in the order as they are found from source to terminus. Many of the dams in the Columbia River watershed were not created for the specific purposes of water storage or flood protection. Instead, the primary purpose of many of these dams is to produce hydroelectricity. As can be seen in the lists, these dams provide many tens of gigawatts of power. Major dam construction began in the early 20th century and picked up the pace after the Columbia River Treaty in the 1960s, by the mid 1980s all the big dams were finished. Including just the dams listed below, there are 60 dams in the watershed, with 14 on the Columbia, 20 on the Snake, seven on the Kootenay, seven on the Pend Oreille / Clark, two on the Flathead, eight on the Yakima, and t ...
