River Mill Hydroelectric Project
River Mill Hydroelectric Project, also known as River Mill Dam and Station M, is a hydroelectric dam and powerhouse in Clackamas County, Oregon, United States. It is just north of Estacada, Oregon, on the Clackamas River at river mile 23.5 (km 37.8). It received its name from being near a sawmill that was located along the river. The dam has been in continuous production of hydroelectric power since 1911, when its construction was funded by the Portland Railway, Light and Power Company. It was one of four related projects on the Clackamas River: the Oak Grove Hydroelectric Project (developed 1923–56), the North Fork dam (1958), and the Faraday Dam (1907–10), all upstream (south) of River Mill. All but Faraday, demolished 2018, are still owned and operated by the successor company, Portland General Electric. The principal designer of the original Mill Run Dam was the Norwegian immigrant Nils F. Ambursen (1876–1958). Based in Boston, his Ambursen Hydraulic Construction C ...

Estacada, Oregon
Estacada is a city in Clackamas County, Oregon, United States, about southeast of Portland. The 2020 population is estimated to be 3,700. According to the 2010 census, the population in 2010 was 2,695. It is the 89th largest city in Oregon and the 5602nd largest city in the United States. History The Estacadpost officeopened on February 24, 1904 and the city was incorporated in May 1905. The community formed as a camp for workers building a hydroelectric dam on the nearby Clackamas River that was to supply Portland with electricity. At the time, the river was relatively inaccessible by road, forcing the Oregon Power Railway Company to build a railway to the vicinity of the river to transport crews to the river for the construction of the dam. After the construction of the Hotel Estacada, the town became a weekend destination on the railroad line for residents of Portland. During the week, the train carried freight and work crews to and from Portland. Following the development o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon State Historic Preservation Office
The Oregon Parks and Recreation Department (OPRD), officially known (in state law) as the State Parks and Recreation Department, is the government agency of the U.S. state of Oregon which operates its system of state parks. In addition, it has programs to protect and provide public access to natural and historic resources within the state, including the State Historic Preservation Office, Oregon Heritage Commission, Oregon Commission on Historic Cemeteries, recreation trails, the Ocean Shores Recreation Area, scenic waterways and the Willamette River Greenway. The department's chief sources of funding are the Oregon Lottery, state park user fees. and recreation vehicle license fees.

Dams On The National Register Of Historic Places In Oregon
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, tap water, human consumption, Industrial water, 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 Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), 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 Oregon
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 Clackamas County, Oregon
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] |

Energy Infrastructure Completed In 1911
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 ...

Society For Industrial Archeology Newsletter
The Society for Industrial Archeology (SIA) is a North American nonprofit organization dedicated to studying and preserving historic industrial sites, structures and equipment. It was founded in 1971 in Washington, D.C., and its members are primarily from the United States and Canada, although there is some crossover with similar industrial archaeology organizations in the United Kingdom. SIA's headquarters is currently located in the Department of Social Sciences at Michigan Technological University in Houghton, Michigan. In addition to the national organization, there are thirteen regional chapters throughout the United States. Activities Since its founding in October 1971, SIA members have gathered at an annual conference, which also serves as the annual business meeting required by its bylaws. The annual conference is typically held each spring. The Fall Tour, a second annual gathering usually held in September or October, began in 1972. Both annual events feature visits to loca ...

River Mill Dam Governor Test
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, an ...
