Hills Creek Dam
Hills Creek Dam is a dam about southeast of Oakridge in Lane County, Oregon, United States. It impounds Hills Creek Reservoir, which has a surface area of and a shoreline of roughly , on the Middle Fork Willamette River. Constructed in 1961 by the United States Army Corps of Engineers (USACE), the dam's purpose is primarily water storage and flood control, and secondarily for recreation, wildlife and waterfowl conservation, and hydropower generation. The earthen dam has a concrete spillway, stands high, and impounds of water. There are two hydropower-generating units capable of producing a total of 30 megawatts. The dam is one of 13 USACE projects in the Willamette Valley, including two others further downstream on the Middle Fork Willamette, Lookout Point Lake and Dexter Reservoir.

Hills Creek Reservoir Aerial
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical prominence requirement, typically or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willamette Valley
The Willamette Valley ( ) is a long valley in Oregon, in the Pacific Northwest region of the United States. The Willamette River flows the entire length of the valley and is surrounded by mountains on three sides: the Cascade Range to the east, the Oregon Coast Range to the west, and the Calapooya Mountains to the south. The valley is synonymous with the cultural and political heart of Oregon and is home to approximately 70 percent of its population including the five largest cities in the state: Portland, Eugene, Salem, Gresham, and Hillsboro. The valley's numerous waterways, particularly the Willamette River, are vital to the economy of Oregon, as they continuously deposit highly fertile alluvial soils across its broad, flat plain. A massively productive agricultural area, the valley was widely publicized in the 1820s as a "promised land of flowing milk and honey." Throughout the 19th century, it was the destination of choice for the oxen-drawn wagon trains of emigr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Lane County, Oregon
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams 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, 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] |

Hills Creek (Oregon)
Hills Creek is a tributary, about long, of the Middle Fork Willamette River in the U.S. state of Oregon. From its headwaters on Juniper Ridge in the Cascade Range, the creek flows northwest through Lane County and the Willamette National Forest for its entire course. Hills Creek enters the Hills Creek Reservoir at Hills Creek Dam on the Middle Fork about upstream from Oakridge. Forest Road 23 (Hills Creek Road) runs roughly parallel to the creek for most of its length. Hills Creek was named for John J. Hill, who settled near the mouth of the creek in 1870. The dam and lake take their names from the creek. Recreation The lower of the creek are stocked with rainbow trout that reach in length. The stream also supports wild coastal cutthroat trout. Whitewater enthusiasts sometimes run a stretch of the creek that has been called "one of the more demanding creeks in the Eugene area". ( Eugene is about northwest of the mouth of the creek.) Rapids vary from class 4 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Dexter Reservoir
Dexter Reservoir (also known as Dexter Lake) is a reservoir in Lane County, in the U.S. state of Oregon. It is about southeast of Eugene on the Middle Fork Willamette River, immediately downriver from Lookout Point Lake, another reservoir. The communities of Dexter and Lowell are near the lake. Oregon Route 58 follows the lake's southern shore, while Pengra Road parallels the lake's northern shore as far east as Lowell. Dexter Dam, high, impounds up to of water in the reservoir. The powerhouse at the dam can generate 15,000 kilowatts of electricity. The lake and three adjacent state parks are used for water sports and other outdoor recreation. History The two reservoirs, Dexter and Lookout Point, were created in 1954 when the United States Army Corps of Engineers finished building the dams that contain them. Dexter exists partly to control water surges from the upstream lake during Lookout Point's production of hydroelectricity. Dexter Lake's water levels vary greatly, w ...

Lookout Point Lake
Lookout Point Lake (also Lookout Point Reservoir) is a large reservoir on the Middle Fork Willamette River in Lane County, Oregon, United States. It was created in 1953 with the construction of Lookout Point Dam. The downstream end of the reservoir is about southeast of Eugene. It lies immediately upriver from Dexter Lake, another reservoir. The city of Lowell is nearby, along the north shore of Dexter Lake. Oregon Route 58 follows the lake's southern shore and Boundary Road the northern shore. The lake, about long, continues upriver to within about of Oakridge. Lookout Point Dam, high, impounds up to of water. It helps control flooding, generates electricity, and provides a place for boating and other outdoor recreation. History The two reservoirs, Lookout Point and Dexter, were created in the early 1950s, when the United States Army Corps of Engineers finished building the dams that contain them. Dexter exists partly as a re-regulating basin that controls water surges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...

Oakridge, Oregon
Oakridge is a city in Lane County, Oregon, United States. The population was 3,205 as of the 2010 census. It is located east of Westfir on Oregon Route 58, about east of Eugene and southeast of Portland. Surrounded by the Willamette National Forest and the Cascade Range, Oakridge is popular with outdoor enthusiasts for its hiking, mountain biking, wildflowers, fly fishing, birding, watersports, and the nearby Willamette Pass Resort. The city was originally a community called "Hazeldell", and its post office was established on July 26, 1888. When a station on the Southern Pacific Railroad opened in May 1912, it was named "Oak Ridge" by a railroad executive for the surrounding topography, and on July 19 of that year the name was changed to be spelled as a single word. The economy of Oakridge and nearby Westfir is centered on recreation. Since the lumber mills closed in the 1980s, the economy has been transitioning, with a new general store opening in 2010, a bakery i ...
