South Fork Coos River
The South Fork Coos River is a tributary, about long, of the Coos River in the U.S. state of Oregon. Formed by the confluence of the Williams River and Tioga Creek, it begins in eastern Coos County near the Douglas County line and flows generally northwest through the Southern Oregon Coast Range. East of the city of Coos Bay, it joins the Millicoma River to form the Coos River. This larger river, only about long, empties into the eastern end of Coos Bay, which connects to the Pacific Ocean. Course From its source, the river flows north through forests, receiving Mink Creek from the left. About further downstream, the river turns west, and Fall Creek enters from the right. Over the next stretch, Coal and Fannin creeks enter from the left and Elk Creek from the right. The river then turns south before Rock Crusher and Burma creeks enter from the left at about river mile (RM) 20 or river kilometer (RK) 32. Turning west, the river receives Cox Creek from the left.

Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Dellwood, Oregon
Dellwood is an unincorporated community in Coos County, Oregon, United States. It is about east of Coos Bay, east of Oregon Route 241 on the South Fork Coos River. Dellwood was originally named Idlewood, but when a post office was established there in 1940, postal officials did not approve the name because of its similarity to Idleyld in Douglas County. Dellwood was chosen from among several suggestions for its similarity to the old name. The post office closed in 1954. Dellwood is the site of a Weyerhaeuser log yard and was once a log dump for sending rafts of logs downriver to Coos Bay for export. Access to the South Fork Coos River above Dellwood for recreational use, including hunting and fishing, is regulated by Weyerhaeuser. The Weyerhaeuser sawmill A sawmill (saw mill, saw-mill) or lumber mill is a facility where logging, logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whitewater
Whitewater forms in a rapid context, in particular, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that 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 consistent over time. Increase ...

Head Of Tide
Head of tide, tidal limit or tidehead is the farthest point upstream where a river is affected by tidal fluctuations, or where the fluctuations are less than a certain amount. This applies to rivers which flow into tidal bodies such as oceans, bays and deltas. Though this point may vary due to storms, spring tides, and seasonal or annual differences in water flows, there is generally an average point that is accepted as the head of tide (in Great Britain this is the Normal Tidal Limit, typically noted on Ordnance Survey maps as 'NTL'). A river's tidal data are recorded at various locations downstream of this point. A river's head of tide may be considered the upper boundary of its estuary. The head of tide is important in surveying, navigation, and fisheries management, and thus many jurisdictions establish a legal head of tide. As the head of tide is useful for navigation, separate maps can be made of the tidal zones up to the head of tide, such as was done in New Jersey. Th ...

Weyerhauser
Weyerhaeuser () is an American timberland company which owns nearly of timberlands in the U.S., and manages an additional of timberlands under long-term licenses in Canada. The company also manufactures wood products. It operates as a real estate investment trust. History In 1904, after years of successful Mississippi River-based lumber and mill operations with Frederick Denkmann and others, Frederick Weyerhäuser moved west to fresh timber areas and founded the Weyerhäuser Timber Company. Fifteen partners and of Washington timberland were involved in the founding, and the land was purchased from James J. Hill of the Great Northern Railway. In 1929, the company built what was then the world's largest sawmill in Longview, Washington. Weyerhaeuser's pulp mill in Longview, which began production in 1931, sustained the company financially during the Great Depression. In 1959, the company eliminated the word "Timber" from its name to better reflect its operations. In 1965 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hatchery
A hatchery is a facility where eggs are hatched under artificial conditions, especially those of fish, poultry or even turtles. It may be used for ex-situ conservation purposes, i.e. to breed rare or endangered species under controlled conditions; alternatively, it may be for economic reasons (i.e. to enhance food supplies or fishery resources). Fish hatcheries Fish hatcheries are used to cultivate and breed a large number of fish in an enclosed environment. Fish farms use hatcheries to cultivate fish to sell for food, or ornamental purposes, eliminating the need to find the fish in the wild and even providing some species outside their natural season. They raise the fish until they are ready to be eaten or sold to aquarium stores. Other hatcheries release the juvenile fish into a river, lake or the ocean to support commercial, tribal, or recreational fishing or to supplement the natural numbers of threatened or endangered species, a practice known as fish stocking.

Oregon Department Of Fish And Wildlife
The Oregon Department of Fish and Wildlife (ODFW) is a government agency of the U.S. state of Oregon responsible for programs protecting Oregon fish and wildlife resources and their habitats. The agency operates hatcheries, issues hunting and angling licenses, advises on habitat protection, and sponsors public education programs. Its history dates to the 1878 establishment of the office of Columbia River Fish Warden. Since 1931, enforcement of Oregon's Fish and Game laws has been the responsibility of the Oregon State Police rather than separate wardens. Hunting, Fishing, Shellfishing and Wildlife viewing A study was done in 2008 by ODFW and Travel Oregon to find the results of expenditures made throughout Oregon from residents and nonresidents that participated in the economic significance of fishing, hunting, wildlife viewing, and shellfish harvesting in Oregon. Roughly 2.8 million residents and non-residents participated in either hunting, fishing, wildlife viewin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Cutthroat Trout
The coastal cutthroat trout (''Oncorhynchus clarkii clarkii''), also known as the sea-run cutthroat trout, blue-back trout or harvest trout, is one of the several subspecies of cutthroat trout found in Western North America. The coastal cutthroat trout occurs in four distinct forms. A semi-anadromous or sea-run form is the most well known. Freshwater forms occur in both large and small rivers and streams and lake environments. The native range of the coastal cutthroat trout extends south from the southern coastline of the Kenai Peninsula in Alaska to the Eel River in Northern California. Coastal cutthroat trout are resident in tributary streams and rivers of the Pacific basin and are rarely found more than from the ocean. Adults migrate from the ocean to spawn in fresh water. Juveniles migrate to the sea where they feed and become sexually mature before returning to fresh water to overwinter and spawn. Unlike steelhead and Pacific salmon, coastal cutthroat do not make length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent ex ...

Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family (biology), family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon or "silvers". The scientific species name is based on the Russian language, Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and average and , occasionally reaching up to . They also develop a large kype (hooked beak) during spawning. Mature females may be darker than males, with both showing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinook Salmon
The Chinook salmon (''Oncorhynchus tshawytscha'') is the largest and most valuable species of Pacific salmon in North America, as well as the largest in the genus '' Oncorhynchus''. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name ''chavycha'' (чавыча). Chinook are anadromous fish native to the North Pacific Ocean and the river systems of western North America, ranging from California to Alaska, as well as Asian rivers ranging from northern Japan to the Palyavaam River in the Arctic northeast Siberia. They have been introduced to other parts of the world, including New Zealand, thriving in Lake Michigan Great Lakes of North America and Michigan's western rivers, and Patagonia. A large Chinook is a prized and sought-after catch for a sporting angler. The flesh of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
