Pit 3 Dam
Pit-3 Dam (also known as Pit Number Three Dam and Dam Number Three) is a hydroelectricity, hydroelectric dam on the Pit River in northern California in the United States. It forms Lake Britton, and is owned by the Pacific Gas and Electric Company (PG&E). Specifications Pit 3 is a curved concrete gravity dam with a height of and length of . The dam has a gated spillway with three steel gates and three inflatable rubber gates. An intake structure at the dam diverts water into a diameter, long tunnel that connects to the Pit 3 hydroelectric plant. There are three 23.3 Megawatt, MW generators, for a total capacity of 69.9 MW. Lake Britton, formerly known as Pit 3 Reservoir, has a maximum water level of ; however, the lake is usually kept below to avoid flooding parts of McArthur–Burney Falls Memorial State Park. The gross storage capacity is and the usable (active) storage is . The lake level changes on a weekly basis with greater drawdowns during the weekdays for power gener ...

Pacific Crest Trail
The Pacific Crest Trail (PCT), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie east of the U.S. Pacific coast. The trail's southern terminus is next to the Mexico–United States border, just south of Campo, California, and its northern terminus is on the Canada–US border, upon which it continues unofficially to the Windy Joe Trail within Manning Park in British Columbia; it passes through the states of California, Oregon, and Washington. The Pacific Crest Trail is long and ranges in elevation from roughly above sea level near the Bridge of the Gods on the Oregon–Washington border to at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks. Its midpoint is near Chester, California (near Mt. Lassen), where the Sierra and Cascade mountain ranges meet. It was d ...

Buildings And Structures In Shasta County, California
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 artistic ...

Pacific Gas And Electric Company Dams
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Dams On The Pit River
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 ...

Lake Britton
Lake Britton is a reservoir located in Shasta County, California. It is known for its wide variety of bass and trout. Its main body is situated to the west of State Route 89, and is mostly surrounded by PG&E Land, Forest Service Land, and McArthur-Burney Falls Memorial State Park. Along the north shore lies North Shore and Dusty Campgrounds. It is fed by the Pit River and has tributaries of Clark Creek, Burney Creek, and Hat Creek and is impounded by the Pit #3 Dam. A bridge, owned by the Great Shasta Rail Trail, which spans Lake Britton (just east of Hwy 89) was used for the railroad bridge scene in the 1986 film '' Stand By Me''.; special section, pp. S3, S8.

Pit 5 Dam
Pit 5 Dam is a run-of-the-river hydroelectric dam on the Pit River in Shasta County, northeastern California, about south of Big Bend. It is part of the Pit 3-4-5 hydroelectric project owned by Pacific Gas & Electric Company. Specifications The concrete gravity diversion dam is high and long. It has a gated spillway controlled by four steel wheel gates, and a diameter river outlet for regular releases. An intake structure diverts water into a long penstock to the Pit 5 Tunnel forebay reservoir, from which a second tunnel connects to the Pit 5 power station. There are four 40 MW generating units, each fed by a -long penstock. History The dam and power station were authorized in 1942 and constructed as a wartime project, and the first power was generated on April 29, 1944. Construction of the dam and power station dewatered a stretch of the Pit River known as the "Big Bend". When the projects were relicensed in 2007, a minimum release into the river was established, to pro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

McArthur–Burney Falls Memorial State Park
McArthur–Burney Falls Memorial State Park is the second oldest state park in the California State Parks system, located approximately north of Burney, California. The park offers camping, fishing, watersports, hiking and horseback riding facilities. The park is mainly known for the waterfall, Burney Falls, at the entrance of the park. Wildlife in the park includes bass, trout, Steller's jay, squirrels, woodpeckers, deer, and on rare occasion, black bear. Geology The park is within the Cascade Range and Modoc Plateau natural region, with of forest and of streamside and lake shoreline, including a portion of Lake Britton. The park's centerpiece is the Burney Falls. Burney Creek originates from the park's underground springs, with additional water coming from springs, which join the creek to create a mist-filled basin. Below the falls, the creek flows into Lake Britton. The park's landscape was created by volcanic activity as well as erosion from weather and streams. ...
