Siuslaw River
The Siuslaw River ( ) is a river, about long, that flows to the Pacific Ocean coast of Oregon in the United States. It drains an area of about in the Central Oregon Coast Range southwest of the Willamette Valley and north of the watershed of the Umpqua River. It rises in the mountains of southwestern Lane County, about west of Cottage Grove. It flows generally west-northwest through the mountains, past Swisshome, entering the Pacific at Florence. The head of tide is upstream. It is part of the homeland of the Siuslaw people, after whom it is named. Citizens of the Siuslaw nation lived in villages along the river until 1860 when they were forcibly removed to an Indian reservation in Yachats whereupon their homes, farms, gardens and villages were destroyed and occupied by U.S. settler-colonists. The valley of the river has been one of the productive timber regions in Oregon. The lower course of the river passes through Siuslaw National Forest. The Coos Bay branch of the C ...

Alsea Language
Alsea or Alsean (also Yakonan) was two closely related speech varieties spoken along the central Oregon coast until the early 1950s. They are sometimes taken to be different languages, but it is difficult to be sure given the poor state of attestation; Mithun believes they were probably dialects of a single language.Marianne Mithun, Mithun, Marianne. (1999). ''The languages of Native North America''. Cambridge: Cambridge University Press. (hbk); Varieties # Alsea (Alséya) ''(†)'' # Yaquina (Yakwina, Yakona) ''(†)'' Both are now Extinct language, extinct. The name ''Alsea'' derives from the Coos language, Coosan name for them, ''alsí'' or ''alsí·'', and the Marys River Kalapuyan name for them, ''alsí·ya''. Alsea was last recorded in 1942 from the last speaker, John Albert, by J. P. Harrington. The name ''Yaquina'' derives from the Alsean name for the Yaquina Bay and the Yaquina River region, ''yuqú·na''. Yaquina was last recorded in 1884 by James Owen Dorsey. Ling ...

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. The ...

List Of Longest Streams Of Oregon
Seventy-seven rivers and creeks of at least 50 miles (80 km) in total length are the longest streams of the U.S. state of Oregon. All of these streams originate in the United States except the longest, the Columbia, which begins in the Canadian province of British Columbia and flows 1,249 miles (2,010 km) to the sea near Astoria. The second-longest, the Snake River, which at is the only other stream of more than on the list, begins in Wyoming and flows through parts of Idaho and Washington, as well as Oregon. Some of the other streams also cross borders between Oregon and California, Nevada, Idaho, or Washington, but the majority flow entirely within Oregon. The ''Atlas of Oregon'' ranks 31 rivers in the state by average streamflow; the top five are the Columbia, Snake, Willamette, Santiam, and Umpqua. Not all Oregon rivers with high average flows are on this list of longest streams because neither their main stems nor any of their tributaries (includin ...

Wetlands
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

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] |
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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cushman, Oregon
Cushman is an unincorporated community in Lane County, Oregon, United States. It is located on the north bank of the Siuslaw River on Oregon Route 126, between Tiernan and Florence. Cushman was a station Coos Bay Branch of the Southern Pacific Railroad (today the Coos Bay Rail Link), named for local residents C. C. and I. B. Cushman. It was a mile east of the community of Acme, but the railroad already had a station named Acme, so the name "Cushman" was chosen instead. The post office was moved from Acme in 1916 and renamed to match the station; it closed in 1961. Cushman has a historic store that was built in 1889 and expanded in 1925, and there is a swing span railroad bridge across the river there. The bridge opened to allow ocean-going barges to reach a now-closed sawmill in Mapleton. In 1940, Cushman had a population of 145 and a full-service port. At that time the hills above the community produced Port Orford-cedar, a large evergreen coniferous tree native to the region ...

Coos Bay Rail Link
The Coos Bay Rail Line is a railroad line from the Willamette Valley to the Port of Coos Bay on the Oregon Coast and Coquille, Oregon, in the United States. It is owned and operated by the Oregon International Port of Coos Bay. The rail is operated by a subsidiary for the Port of Coos Bay - Coos Bay Rail Line Inc. History On September 21, 2007, Central Oregon and Pacific Railroad (CORP) elected to shut down most of its Coos Bay branch. The track was closed between Vaughn, Oregon (west of Noti) and Coquille, Oregon (south of Coos Bay). This action was taken after it was revealed that the nine aging tunnels on the line required repairs that were internally estimated to cost up to $7 million. Some local opinion regarded this action unfavorably, as the railroad asked for state funds to repair their private rail line. On October 23, 2007, the Port of Coos Bay filed a $15 million lawsuit against CORP, in response to its closing of the Coos Bay Branch. The suit claims that CORP failed ...

Siuslaw National Forest
The Siuslaw National Forest ( ) is a national forest in western Oregon in the United States. Established in 1908, the Siuslaw is made up of a wide variety of ecosystems, ranging from coastal forests to sand dunes. Geography The Siuslaw National Forest encompasses more than along the central Oregon Coast between Coos Bay and Tillamook, and in some places extends east from the ocean, beyond the crest of the Oregon Coast Range, almost reaching the Willamette Valley. The forest lies primarily in Lane County (39% of the forest) and Lincoln County (27% of the forest); the rest in descending order of land area are Tillamook, Douglas, Yamhill, Benton, Coos, and Polk counties. It includes the Sand Lake Recreation Area and the Oregon Dunes National Recreation Area. The Forest Supervisor's office is located in Corvallis, and the Siuslaw is broken up into two ranger districts—the Hebo Ranger District, with approximately , and the Central Coast Ranger District, with approximate ...
