Umpqua River
The Umpqua River ( ) on the Pacific coast of Oregon in the United States is approximately long. One of the principal rivers of the Oregon Coast and known for bass and shad, the river drains an expansive network of valleys in the mountains west of the Cascade Range and south of the Willamette Valley, from which it is separated by the Calapooya Mountains. From its source northeast of Roseburg, the Umpqua flows northwest through the Oregon Coast Range and empties into the Pacific at Winchester Bay. The river and its tributaries flow almost entirely within Douglas County, which encompasses most of the watershed of the river from the Cascades to the coast. The "Hundred Valleys of the Umpqua" form the heart of the timber industry of southern Oregon, generally centered on Roseburg. The Native Americans in the Umpqua's watershed consist of several tribes, such as the Lower and Upper Umpqua (for which the river is named), and the Kalapuya. These tribes witnessed much of the Gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Americans In The United States
Native Americans (also called American Indians, First Americans, or Indigenous Americans) are the Indigenous peoples of the Americas, Indigenous peoples of the United States, particularly of the Contiguous United States, lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately. The European colonization of the Americas from 1492 resulted in a Population history of Indigenous peoples of the Americas, precipitous decline in the size of the Native American ...

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 ba ...

Smith River (Umpqua River)
The Smith River is a tributary of the Umpqua River in the U.S. state of Oregon. It drains of the Central Oregon Coast Range between the watershed of the Umpqua to the south and the Siuslaw River to the north. Rising in northern Douglas County about north of Drain, the river flows generally west in a winding course through the mountains, passing through the Siuslaw National Forest for about in its lower course. It joins the Umpqua from the north across from Reedsport, about from the mouth of the Umpqua on the Pacific Ocean. The river is named for Jedediah Smith, who in 1828 led a party of explorers from Utah overland to northern California and southern Oregon. From California, they traveled north to the Umpqua River, camping along its banks near the mouth of the Smith River on July 13. An attack by Native Americans on July 14 killed 15 of Smith's party. One man escaped by heading north to Tillamook and then Fort Vancouver. Smith and two others who were not in camp at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navigability
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel (e.g. boats) to pass safely. Navigability is also referred to in the broader context of a body of water having sufficient under keel clearance for a vessel. Such a navigable water is called a ''waterway'', and is preferably with few obstructions against direct traverse that need avoiding, such as rocks, reefs or trees. Bridges built over waterways must have sufficient clearance. High flow speed may make a channel unnavigable due to risk of ship collisions. Waters may be unnavigable because of ice, particularly in winter or high-latitude regions. Navigability also depends on context: a small river may be navigable by smaller craft such as a motorboat or a kayak, but unnavigable by a larger cargo ship, freighter or cruise ship. Shallow rivers may be made navigable by the installation of locks that regulate flow and increase upstream water level, or by dredgi ...

Head Of Tide
Head of tide, tidal limit or tidehead is the furthest point upstream where a river is affected by tidal fluctuations, or where the fluctuations are less than a certain amount. The river section influenced by tides and marine forces, but without salinity is a tidal river. Downstream areas are brackish and termed estuaries. Although 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'). 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.

Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributary, tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an Fish migration#Classification, anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to Spawn (biology), spawn after living two to three years in the ocean. 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 Fish hatchery, hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent except Antarctica.

Interstate 5
Interstate 5 (I-5) is the main north–south Interstate Highway System, Interstate Highway on the West Coast of the United States, running largely parallel to the Pacific coast of the contiguous U.S. from Mexico to Canada. It travels through the states of California, Oregon, and Washington (state), Washington, serving several large cities on the West Coast, including San Diego, Los Angeles, Sacramento, California, Sacramento, Portland, Oregon, Portland, and Seattle. It is the only continuous Interstate highway to touch both the Mexico–United States border, Mexican and Canada–United States border, Canadian borders. Upon crossing the Mexican border at its southern terminus, the highway continues to Tijuana, Baja California, as Mexican Federal Highway 1 (Fed. 1). Upon crossing the Canadian border at its northern terminus, it continues to Vancouver as British Columbia Highway 99 (BC 99). I-5 was originally created in 1956 as part of the Interstate Highw ...

Great Flood Of 1862
The Great Flood of 1862 was the largest flood in the recorded history of California, Oregon, and Nevada, inundating the western United States and portions of British Columbia and Mexico. It was preceded by weeks of continuous rains and snows that began in Oregon in November 1861 and continued into January 1862. This was followed by a record amount of rain from January 9–12, and contributed to a flood that extended from the Columbia River southward in western Oregon, and through California to San Diego, as well as extending as far inland as the Washington Territory (now Idaho), the Utah Territory (now Nevada and Utah), and the western New Mexico Territory (now Arizona). The event dumped an equivalent of of precipitation in California, in the form of rain and snow, over a period of 43 days. Immense snowfalls in the mountains of far western North America caused more flooding in Idaho, Arizona, New Mexico, as well as in Baja California and Sonora, Mexico the following spring and ...
