Elk River (Oregon)
The Elk River is in southwestern Oregon in the United States. About long, the river drains a remote area of the Coast Range into the Pacific Ocean. Rising in the mountains in northern Curry County, in the Siskiyou National Forest at confluence of its north and south forks, the river initially flows generally west along the south edge of the Grassy Knob Wilderness. It then flows northwest, approaching the coast north of Port Orford and entering the Pacific between Cape Blanco to the north and The Heads to the south. Course From the confluence of its two forks, Elk River flows generally west and northwest for about . All but the lowermost of it are in the Rogue River – Siskiyou National Forest. Forest Road 5325 follows the river along its left bank, becoming County Road 208 (Elk Creek Road) after leaving the national forest. County Road 208 ends when it reaches U.S. Route 101 about by water from the mouth of the river. In its first stretch, Elk River receives McCurdy ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Orford Reef
Orford Reef is a reef located off Cape Blanco on the southern coast of Oregon in the United States. The reef is situated around eight small rock islands: Best Rock, Long Brown Rock, Unnamed Rock, Square White Rock, Seal Rock, Conical White Rock, West Conical Rock, and Arch Rock. The reef includes forests of bull kelp up to long, which provide protective habitat for numerous animals, including the bat ray, big skate, broadnose sevengill shark, cabezon, kelp bass, leopard shark, spiny dogfish, kelp greenling, plumose anemone, and numerous species of rockfish. The reef also supports more than 39,000 seabirds, including 5% of the common murre nesting population in Oregon. The Oregon Coast Aquarium in Newport, Oregon contains a simulated version of Orford Reef in its Passages of the Deep exhibit. Common species in the reef Spiny dogfish shark A grey or brown shark with white spots scattering it's back and just like regular sharks, spiny dogfish don't have an anal fin, but they ...

Copper Salmon Wilderness
The Copper Salmon Wilderness is a protected wilderness area in the Southern Oregon Coast Range and is part of the Rogue River–Siskiyou National Forest. The wilderness area was created by the Omnibus Public Land Management Act of 2009, which was signed into law by President Barack Obama on March 30, 2009. The Copper Salmon Wilderness is located along the North and South Forks of Elk River and the upper Middle Fork of Sixes River. The area contains one of the nation's largest remaining stands of low-elevation old-growth forest and one of the healthiest salmon, steelhead, and cutthroat trout runs in the continental United States along the north Fork of the Elk River, as well as stands of vulnerable Port Orford cedar and endangered marbled murrelets and northern spotted owls.

Sixes River
The Sixes River flows about through coastal forests in southwestern Oregon in the United States. It drains a rugged region of the Klamath Mountains along the Pacific north of Port Orford. It rises in the mountains of northern Curry County, south of Sugarloaf Mountain in the Rogue River – Siskiyou National Forest. It flows generally west, through Grassy Knob Wilderness and the small community of Sixes, and eventually enters the Pacific just north of Cape Blanco, the westernmost point in Oregon. The mouth of the river is along the coast in Cape Blanco State Park. Name Accounts vary as to the origin of the name "Sixes". One local postmaster said Sixes was named for a Native American chief. Another source said that in 1851, the river was usually called the "Sikhs River" after the Chinook Jargon word for "friend", and on maps it was called the "Sequalchin River". Another source says the Native American name for the river was "Sa-qua-mi". Hodge's ''Handbook of American Indian ... [...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. Increased f ...

Main Stem
In hydrology, a mainstem (or trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". Water enters the mainstem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton system, the entire mainstem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the mainstem below the tributary of the next highest rank gets the highest num ...

National Wild And Scenic River
The National Wild and Scenic Rivers System was created by the Wild and Scenic Rivers Act of 1968 (Public Law 90-542), enacted by the U.S. Congress to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition for the enjoyment of present and future generations. The Act is notable for safeguarding the special character of these rivers, while also recognizing the potential for their appropriate use and development. It encourages river management that crosses political boundaries and promotes public participation in developing goals for river protection. The Act, signed into law by President Lyndon B. Johnson in the height of the United States environmental era, states:"It is hereby declared to be the policy of the United States that certain selected rivers of the Nation which, with their immediate environments, possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic, cultural or other similar ...

Drift Boat
A Drift Boat is an evolution of the open-water dory, converted for use in rivers. The design is characterized by a wide, flat bottom, flared sides, a narrow, flat bow (ship), bow, and a pointed stern. A Rocker is used along an arc from bow to stern along the bottom of the boat. It is this constant rocker that allows the boat to spin about its center for ease in maneuvering in rapids. Hull materials The earliest drift boats were made out of various types of wood. Later boats were made with lower maintenance materials like aluminum, fiberglass, or plastic. In 1992 the film "A River Runs Through It" featured a wooden drift boat running "the shoots", a series of rapids (filmed in Montana ). This portrayal of using drift boats in class I -IV rapids is only one application for this unique watercraft. Today river fishing is among the major uses of these boats. Innovation has changed the design from anglers primarily sitting in the boat while fishing, to today's application of anglers st ...

Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon 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 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 a pronounced hook on the nose. Re ... [...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 except ...

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 lengthy m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
