Pit River
The Pit River is a major river draining from northeastern California into the state's Central Valley. The Pit, the Klamath and the Columbia are the only three rivers in the U.S. that cross the Cascade Range. The longest tributary of the Sacramento River, it contributes as much as eighty percent of their combined water volume into the Shasta Lake reservoir; the junction of their Shasta Lake arms is northeast of Shasta Dam. The main stem of the Pit River is long, and some water in the system flows to the Sacramento River measuring from the Pit River's longest source. The Pit River drains a sparsely populated volcanic highlands area in Modoc County's Warner Mountains, passing through the south end of the Cascade Range in a deep canyon northeast of Redding. The river is so named because of the semi-subterranean permanent winter homes and large 'sweat houses' that the Pit River Tribe dug, and their pit traps for game that came to water at the river. The river is a pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achomawi
Achomawi (also Achumawi, Ajumawi and Ahjumawi) are the northerly nine (out of eleven) bands of the Pit River tribe of Palaihnihan Native Americans who live in what is now northeastern California in the United States. These 5 autonomous bands (also called "tribelets") of the Pit River Indians historically spoke slightly different dialects of one common language, and the other two bands spoke dialects of a related language, called Atsugewi. The name "Achomawi" means river people and properly applies to the band which historically inhabited the Fall River Valley and the Pit River from the south end of Big Valley Mountains, westerly to Pit River Falls. The nine bands of Achumawi lived on both sides of the Pit River from its origin at Goose Lake to Montgomery Creek, and the two bands of Atsugewi lived south of the Pit River on creeks tributary to it in the Hat Creek valley and Dixie Valley. Population Achomawi speaking territories reached from Big Bend to Goose Lake. This land wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Valley (California)
The Central Valley is a broad, elongated, flat valley that dominates the interior of California, United States. It is wide and runs approximately from north-northwest to south-southeast, inland from and parallel to the Pacific coast. It covers approximately , about 11% of California's land area. The valley is bounded by the California Coast Ranges, Coast Ranges to the west and the Sierra Nevada to the east. The Central Valley is a region known for its agricultural productivity. It provides a large share of the food produced in California, which provides more than half of the fruits, vegetables, and nuts grown in the United States. More than of the valley are irrigated via reservoirs and canals.

Modoc National Forest
Modoc National Forest is a National forest (United States), U.S. national forest in Northeastern California. Geography The Modoc National Forest protects parts of Modoc County, California, Modoc (82.9% of acreage), Lassen County, California, Lassen (9.4%), and Siskiyou County, California, Siskiyou (7.7%) counties. Most of the forest was covered by immense lava flows occurring over the last 500,000 years. The eastern part of the forest east of Alturas, California, Alturas contains the Warner Mountains. The Warner Mountains drop steeply on the eastern slopes, whereas the western flank has a more gentle topography. Ecology Due to the elevation and precipitation differences, the forests hosts List of plants on the Modoc National Forest, a large number of plant species. The western side of the brushy foothills consist mostly of bitterbrush and Cercocarpus ledifolius, curl-leaf mahogany. As elevation increases, forests of ponderosa pine, white fir, white and red firs, incense cedar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warner Mountains
The Warner Mountains are an -long mountain range running north–south through northeastern California and extending into southern Oregon in the United States. The range lies within the northwestern corner of the Basin and Range Province, extending from the northeastern corner of Lassen County, California, through eastern Modoc County, California (east of Alturas), and northward into Lake County, Oregon (east of Lakeview). The highest peak in the range is Eagle Peak with an elevation of . The range is part of the Modoc National Forest in California and Fremont National Forest in Oregon. The southern portion of the range includes Eagle Peak and Warren Peak, within the South Warner Wilderness. Geography The Warner Range is not part of the Sierra Nevada range or the Cascade Range, but part of the Great Basin Ranges. It is in the semi-arid, sparsely-populated northeastern corner of California and the south-central portion of Oregon. The range is a classic example of hor ...

Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

Whitewater
Whitewater forms in the context of rapids, in particular, when a river's Stream gradient, gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that foam, froths, making the water appear opaque and white. The term "whitewater" also has a broader meaning, applying to any river or creek that has a significant number of rapids. The term is also used as an adjective describing boating on such rivers, such as whitewater canoeing or whitewater kayaking. Fast rivers Four factors, separately or in combination, can create rapids: gradient, constriction, obstruction, and flow rate. Gradient, constriction, and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams. Streambed topography Streambed topography is the primary factor in creating rapids, and is generally consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly Fishing
Fly fishing is an angling technique that uses an ultra-lightweight lure called an artificial fly, which typically mimics small invertebrates such as flying and aquatic insects to attract and catch fish. Because the mass of the fly lure is insufficient to overcome air resistance, it cannot be launched far using conventional gears and techniques, so specialized tackles are used instead and the casting techniques are significantly different from other forms of angling. It is also very common for the angler to wear waders, carry a hand net, and stand in the water when fishing. Fly fishing primarily targets predatory fish that have significant amount of very small-sized prey in their diet, and can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species (notably black bass). In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Redding, California
Redding is a city in and the county seat of Shasta County, California, and the economic and cultural capital of the Shasta Cascade region of Northern California. Redding lies along the Sacramento River, north of Sacramento, California, Sacramento, and south of California's northern border with Oregon. Its population is 95,542 as of 2022, up from 93,611 at the 2020 United States census, 2020 census. Etymology During the California Gold Rush, Gold Rush, the area that now comprises Redding was called Poverty Flats. In 1868 the first land agent for the Central Pacific Railroad, a former Sacramento politician named Benjamin B. Redding, Benjamin Bernard Redding, bought property in Poverty Flats on behalf of the railroad so that it could build a northern terminus there. In the process of building the terminus, the railroad also built a town in the same area, which they named Redding in honor of Benjamin Redding. In 1874, there was a dispute over the name by local legislators and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shasta Dam
Shasta Dam (called Kennett Dam before its construction) is a concrete arch-gravity dam across the Sacramento River in Northern California in the United States. At high, it is the eighth-tallest dam in the United States. Located at the north end of the Sacramento Valley, Shasta Dam creates Shasta Lake for long-term water storage, flood control, hydroelectricity and protection against the intrusion of saline water. The largest reservoir in the state, Shasta Lake can hold about . Envisioned as early as 1919 as an effort to conserve, control, store, and distribute water to the Central Valley, California's main agricultural region, Shasta was first authorized in the 1930s as a state undertaking. However, bonds did not sell due to the onset of the Great Depression and Shasta was transferred to the federal Bureau of Reclamation as a public works project. Construction started in earnest in 1937 under the supervision of Chief Engineer Frank Crowe. During its building, the dam provid ...
