Copco Lake
Copco Lake was an artificial lake on the Klamath River in Siskiyou County, California, near the Oregon border. The lake's waters were impounded by the Copco Number 1 Dam, which was completed in 1922 as part of the Klamath River Hydroelectric Project. The dam was breached in January 2024 as a component of the Klamath River Renewal Project following decades of activism from the Un-Dam the Klamath movement. The dam structure was fully removed by early October 2024. History Copco Lake was created by the construction of Copco Number 1 Dam. This dam was completed in 1922 by the California Oregon Power Company (COPCO). COPCO was merged into Pacific Power and Light in 1961, and is now known as Pacificorp. Dam removal Copco Number 1 and Number 2 Dams were two of the four dams in the Klamath River Hydroelectric Project which were removed in the 2020s as part of the Klamath River Renewal Project. The social movement to Un-Dam the Klamath had been ongoing for over 20 years. As of Februa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it, with more than 150 Nobel Prize-winners being featured since its inception. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large-format New York City newspaper was released on August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 devi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Northern California
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

List Of Lakes In California
There are more than 3,000 named lakes, reservoirs, and dry lakes in the U.S. state of California. Largest lakes In terms of area covered, the largest lake in California is the Salton Sea, a lake formed in 1905 which is now saline. It occupies in the southeast corner of the state, but because it is shallow it only holds about of water. Tulare Lake in the San Joaquin Valley was larger, at approximately , until it was drained during the later years of the nineteenth century. In terms of volume, the largest lake on the list is Lake Tahoe, located on the California–Nevada border. It holds roughly of water. It is also the largest freshwater lake by area, at , and the deepest lake, with a maximum depth of . Among freshwater lakes entirely contained within the state, the largest by area is Clear Lake, which covers . Many of California's large lakes are actually reservoirs: artificial bodies of fresh water. In terms of both area and volume, the largest of these is ...

Iron Gate Dam (California)
Iron Gate Dam was an earthfill hydroelectric dam on the Klamath River in northern California, outside Hornbrook, California, that opened in 1964. The dam blocked the Klamath River to create the Iron Gate Lake Reservoir. It was the lowermost of a series of power dams on the river, the Klamath River Hydroelectric Project, operated by PacifiCorp. It also posed the first barrier to migrating salmon in the Klamath. The Iron Gate Fish Hatchery was placed just after the dam, hatching salmon and steelhead that were released back into the river. A movement to Un-Dam the Klamath had been ongoing for 20 years to remove the dams. The Iron Gate Dam (National ID CN 001223), along with the John C. Boyle Dam, were two of four on the Klamath River that would be removed under the Klamath Economic Restoration Act. As of February 2016, the states of Oregon and California, the dam owners, federal regulators, and other parties reached an agreement to remove all four dams by the year 2020, pending app ...

Diversion Dam
A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir; instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming an on-ground or groundwater reservoir or a storm drain. An early diversion dam is the Ancient Egyptian Sadd el-Kafara Dam at Wadi Al-Garawi, which was located about twenty five kilometres south of Cairo. Built around 2600 BC for flood control, the structure was 102 metres long at its base and 87 metres wide. It was destroyed by a flood while it was still under construction.Günther Garbrecht: "Wasserspeicher (Talsperren) in der Antike", ''Antike Welt'', 2nd special edition: ''Antiker Wasserbau'' (1986), pp.51-64 (52f.)

Cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
