South Fork Rogue River
The South Fork Rogue River is a tributary of the Rogue River in the U.S. state of Oregon. Rising in the Sky Lakes Wilderness in the Cascade Range, it flows generally northeast through the Rogue River – Siskiyou National Forest to meet the Rogue River downstream of Prospect and slightly upstream of Lost Creek Lake. Course The river begins in Klamath County in the Sky Lakes Wilderness of the Cascade Range. It flows north from Horseshoe Lake for about before turning northeast and entering Jackson County, leaving the wilderness area and entering the Rogue River–Siskiyou National Forest. Over its next , the river flows under Forest Road 37 at Upper South Fork Bridge, passes Upper South Fork Campground and receives Parker Creek from the left near Parker Meadows Campground, then Little Billie, Wickiup, and Sam creeks from the right. Below this, it receives Big Ben Creek from the right. The river then flows under Lower South Fork Bridge, which carries Forest Road 37, and by So ...

Diversion Dam
A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir; instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming an on-ground or groundwater reservoir or a storm drain. An early diversion dam is the Ancient Egyptian Sadd el-Kafara Dam at Wadi Al-Garawi, which was located about twenty five kilometres south of Cairo. Built around 2600 BC for flood control, the structure was 102 metres long at its base and 87 metres wide. It was destroyed by a flood while it was still under construction.Günther Garbrecht: "Wasserspeicher (Talsperren) in der Antike", ''Antike Welt'', 2nd special edition: ''Antiker Wasserbau'' (1986), pp.51-64 (52f.)

Log Jam
A log jam is a naturally occurring phenomenon characterized by a dense accumulation of tree trunks and pieces of large wood across a vast section of a river, stream, or lake. ("Large wood" is commonly defined to be pieces of wood more than in diameter and more than long.) Log jams in rivers and streams often span the entirety of the water's surface from bank to bank. Log jams form when trees floating in the water become entangled with other trees floating in the water or become snagged on rocks, large woody debris, or other objects anchored underwater. They can build up slowly over months or years, or they can happen instantaneously when large numbers of trees are swept into the water after natural disasters. A notable example caused by a natural disaster is the log jam that occurred in Spirit Lake following a landslide triggered by the eruption of Mount St. Helens. Unless they are dismantled by natural causes or humans, log jams can grow quickly, as more wood arriving from ups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Brook Trout
The brook trout (''Salvelinus fontinalis'') is a species of freshwater fish in the char genus ''Salvelinus'' of the salmon family Salmonidae native to Eastern North America in the United States and Canada. Two ecological forms of brook trout have been recognized by the US Forest Service. One ecological form is long-lived potamodromous populations in Lake Superior known as coaster trout or coasters. The second ecological form is the short-living predaceous anadromous populations which are found in northern lakes and coastal rivers from Long Island to Hudson Bay, which are referred to as salters. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook char (or charr), squaretail, brookie, or mud trout, among others. Adult coaster brook trout are capable of reaching sizes over 2'' ''feet in length and weigh up to 6.8'' ''kg (15'' ''lb), whereas adult salters average between 6 and 15'' ''inches in length and weigh between 0. ...

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.

River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Main Stem
In hydrology, a main stem or mainstem (also known as a trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". The mainstem extends all the way from one specific headwater to the outlet of the river, although there are multiple ways to determine which headwater (or first-order tributary) is the source of the main stem. Water enters the main stem 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 ...
