Keswick Dam
Keswick Dam is a concrete gravity dam on the Sacramento River about northwest of Redding, California. Part of the U.S. Bureau of Reclamation's Central Valley Project, the dam is high and impounds the Keswick Reservoir, which has a capacity of . The dam's power plant has three turbines with a generating capacity of 117 megawatts (MW), which, in 1992, was uprated from its original 75 MW. The dam and reservoir serve as an afterbay to regulate peaking power releases from the Shasta Dam upstream. The electrical substation at Keswick Dam distributes power from the Keswick power plant, the power plants at Trinity Dam and Lewiston Dam, the Judge Francis Carr Power plant near Whiskeytown Lake, and the Spring Creek Power plant, which is located just northwest of Keswick Dam. History Water scarcity Water scarcity was felt starting in the 19th century, in the gold-mining era. The discovery of gold mines in the 1840s attracted a flood of immigrants to California. After a few years, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Mining In California
Gold became highly concentrated in California, United States as the result of global forces operating over hundreds of millions of years. Volcanoes, tectonic plates and erosion all combined to concentrate billions of dollars' worth of gold in the mountains of California. During the California Gold Rush, gold-seekers known as "Forty-Niners" retrieved this gold, at first using simple techniques, and then developing more sophisticated techniques, which spread around the world. Geology Geologic evidence indicates that over a span of at least 400 million years, gold that had been widely dispersed in the Earth's crust became more concentrated by geologic actions into the gold-bearing regions of California. Only gold that is concentrated can be economically recovered. Some 400 million years ago, rocks that would be accreted onto western North America to build California lay at the bottom of a large sea. Subsea volcanoes deposited lava and minerals (including gold) onto the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Mountain Mine
Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US. Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc, quartz, and pyrite intermittently from the 1860s until 1963. The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium. One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.U.S., California Announce Settlement to Clean up one of the Country's Most Toxic Waste Sites |
Whiskeytown Dam
Whiskeytown Dam (officially Clair A. Hill Whiskeytown Dam) is an earthfill dam on Clear Creek, a tributary of the Sacramento River of northern California in the United States. The dam is located about west of Redding, and impounds Whiskeytown Lake on the southern flank of the Trinity Mountains. The dam is high, with a storage capacity of of water. History The dam was one of the first units built of the Trinity River Division of the Central Valley Project, a federal water project intended to provide irrigation water to the eponymous Central Valley. Construction started in August 1960 with clearing operations around the dam site, and excavations for the spillway and outlet tunnels began in October. By late 1961, over one-half of the dam embankment was complete. The dam was topped out on February 7, 1963, and the reservoir was allowed to begin filling. On September 28, it was dedicated by President John F. Kennedy to a crowd of more than 10,000 people. Water diverted from ...

Lassen Peak
Lassen Peak ( ), commonly referred to as Mount Lassen, is a lava dome volcano and the southernmost active volcano in the Cascade Range of the Western United States. Located in the Shasta Cascade region of Northern California, it is part of the Cascade Volcanic Arc, which stretches from southwestern British Columbia to northern California. Lassen Peak reaches an elevation of , standing above the northern Sacramento Valley. It supports many flora and fauna among its diverse habitats, which are subject to frequent snowfall and reach high elevations. Lassen Peak has a volume of , making it one of the largest lava domes on Earth. The volcano arose from the former northern flank of now-eroded Mount Tehama about 27,000 years ago, from a series of eruptions over the course of a few years. The mountain has been significantly eroded by glaciers over the last 25,000 years, and is now covered in talus deposits. On May 22, 1915, a powerful explosive eruption at Lassen Peak devastated near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National War Labor Board (1942–1945)
The National War Labor Board, commonly the War Labor Board (NWLB or WLB) was an agency of the United States government established January 12, 1942 by executive order to mediate labor disputes during World War II. History The NWLB was established by President Franklin D. Roosevelt under Executive Order 9017, with William Hammatt Davis as its chair. It was charged with acting as an arbitration tribunal in labor-management dispute cases in order to prevent work stoppages which might hinder the war effort. It administered wage control in national industries such as automobiles, shipping, railways, airlines, telegraph lines, and mining. The Board was originally divided into twelve Regional Administrative Boards which handled both labor dispute settlement and wage stabilization functions for specific geographic regions. The national Board further decentralized in 1943, when it established special tripartite commissions and panels to deal with specific industries on a national bas ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emergency Relief Appropriation Act Of 1935
The Relief Appropriation Act of 1935 was passed on April 8, 1935, as a part of Franklin Delano Roosevelt's New Deal. It was a large public works program that included the Works Progress Administration (WPA), Public Works Administration (PWA), the National Youth Administration, the Resettlement Administration, the Rural Electrification Administration, and other assistance programs. These programs were called the "second New Deal". The programs gave Americans work, for which the government would pay them. The goal was to help unemployment, pull the country out of the Great Depression, and prevent another depression in the future. This was the first and largest system of public-assistance relief programs in American history, and it led to the largest accumulation of national debt. Background Before 1935, many programs focused on direct aid and "the dole". Franklin Delano Roosevelt did not like providing welfare to able workers as it demoralized the unemployed and created dependenc ...

Kern River
The Kern River, previously Rio de San Felipe, later La Porciuncula, is an Endangered, Wild and Scenic river in the U.S. state of California, approximately long. It drains an area of the southern Sierra Nevada mountains northeast of Bakersfield. Fed by snowmelt near Mount Whitney, the river passes through scenic canyons in the mountains and is a popular destination for whitewater rafting and kayaking. It is the southernmost major river system in the Sierra Nevada, and is the only major river in the Sierra that drains in a southerly direction. The Kern River formerly emptied into the now dry Buena Vista Lake and Kern Lake via the Kern River Slough, and Kern Lake in turn emptied into Buena Vista Lake via the Connecting Slough at the southern end of the Central Valley. Buena Vista Lake, when overflowing, first backed up into Kern Lake and then upon rising higher drained into Tulare Lake via Buena Vista Slough and a changing series of sloughs of the Kern River. The lakes wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
