Ugashik River
The Ugashik River is a stream, long, on the Alaska Peninsula of the U.S. state of Alaska. It flows from headwaters near Lower Ugashik Lake and empties into Ugashik Bay, an estuary of the Bering Sea's Bristol Bay. The origin of the name Ugashik is somewhat obscure, although early spelling variants such as Oogashik and Ougashick suggest the name pertains to the source of the river: two waters (lakes) and its muddy character. The river has two major tributaries and one minor: the King Salmon River and the Dog Salmon River both have confluences near the river mouth at Ugashik Bay, while the smaller Dago Creek joins just four miles (6 km) from Smoky Point, where Ugashik Bay and Bristol Bay meet. The river is navigable to a small lagoon located just outside the outlet from Lower Ugashik Lake. A small rapids between the lake and the lagoon serves as the location of a seasonally staffed salmon-counting weir operated by the Alaska Department of Fish and Game. The river hosts ...

Baidarka
The baidarka or Aleutian kayak (Aleut: iqyax) is a watercraft consisting of soft skin (artificial or natural) over a rigid space frame. Its initial design was created by the native Aleut (or Unangan) people of the Aleutian Islands. The Aleut people were surrounded by treacherous waters and required water transportation and a hunting vessel. Due to the geography and climate of the Aleutian Islands, trees and wood were in scarce supply and the people relied primarily on driftwood to create the framework of the kayak, which was covered with the skins of sea mammals. Two types of boats were created, one with a covered deck that was used as a hunting kayak, and another that was open and capable of carrying goods and people from one island to another. Modern baidarkas are fast collapsible rowing boats, based on aluminum alloy frame with skin made of PVC fabric. Often the inflatable buoyancy chambers are embedded into the skin, resulting in increased safety and performance. Some des ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Sockeye Salmon
The sockeye salmon (''Oncorhynchus nerka''), also called red salmon, kokanee salmon, blueback salmon, or simply sockeye, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to in length and weigh . Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to . Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in fresh water. Classification and name origin The sockeye salmon is the third-most common Pacific salmon species, after pink and chum salmon. ''Oncorhynchus'' comes from the Greek ὄγκος (onkos) meaning "barb", and ῥύγχος (rhynchos) meaning "snout". ''Nerka'' is the Russian name for the anadromous form. The name "sockeye" ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoky Point
Smoky Point is a point of land in the U.S. state of Alaska, located at , where Ugashik Bay joins the much larger Bristol Bay. The most easily distinguishable landmark is the United States Coast Guard lighthouse which is visible to mariners on the eastern shore of Bristol Bay and all of Ugashik Bay. The long beaches, shoals, and sandbars of lower Ugashik Bay and the eastern shore of Bristol Bay make navigation through the area particularly troublesome. Shipwrecks, even of smaller vessels, are not unusual. Deaths arising from vessels in distress and from drowning are also commonplace. The combination of extremely rough sea conditions—surf arising in Bristol Bay is commonly 1–5 m (3–16 ft) high—and cold water make survival rates extremely low. On a single day in July 2006, to illustrate, two vessels of the Bristol Bay fishing fleet were lost on the shoals of Smoky Point. The crew of the fishing vessels ''Kaos'' and ''Silver Tide'' were rescued by heroic effort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dago Creek
Dago Creek (Sugpiaq: ''Kuigaa'aq'') is a stream, long, on the Alaska Peninsula in the U.S. state of Alaska. Beginning in a small lake southeast of Egegik, it meanders southwest across the flats to enter Ugashik Bay southeast of Smoky Point. The name derives from the numerous Sicilian fishermen who would anchor in the protected waters during closed fishing periods and collectively celebrate their heritage with plenty of food and wine. At first used in a pejorative way, the Sicilians embraced the terminology and the name stuck, becoming official when the area was first definitively mapped in 1943. The area is still used as a small boat harbor for the nearby village of Pilot Point, especially with the completion of a bulkhead-style dock and boat launch in 1990. Although a few fish swim up, and reportedly spawn in, its waters, the stream is primarily a drain for the multitude of small lakes, marshland and tundra of the coastal zone north of Ugashik Bay. The creek generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dog Salmon River
The Dog Salmon River is a tributary of the Ugashik River in the U.S. state of Alaska. Beginning on the flanks of Mount Kialagvik, it flows northwest through the Alaska Peninsula National Wildlife Refuge to meet the larger river southwest of Ugashik, Alaska, Ugashik, at the head of Ugashik Bay, an arm of Bristol Bay. It descends to the upper reaches of the bay from an elevation of in a valley of the Aleutian Range between Mount Chiginagak and Mount Kialagvik. Among its feeder streams are Figure Eight, Goblet, and Wandering creeks. It is shallow with many oxbow turns and is not navigable. The streambed is a mix of gravel and mud, with its milky glacier headwaters growing increasingly muddy as it progresses. There are many rivers in Alaska bearing the name Dog Salmon River and this river should not be confused with those located on the Yukon-Kuskokwim Delta or eastern Norton Sound. As its name suggests, the river primarily hosts large numbers of Chum Salmon along with smaller n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Salmon River (Ugashik River)
The King Salmon River is a tributary of the Ugashik River in the U.S. state of Alaska. Beginning at Mother Goose Lake in the Aleutian Range, it flows northwest to meet the larger river near the upper reaches of Ugashik Bay. The lake and the upper course of the King Salmon lie within the Alaska Peninsula National Wildlife Refuge. The river's gravel bottom and braided channels are ideal for the many king salmon that spawn in its waters, but they limit navigation to small skiff. There are many rivers in Alaska bearing the name King Salmon River, including tributaries to the Egegik River and Nushagak River systems in southwest Alaska, alone. The name is also occasionally confused with a nickname given the Kenai River, a popular fishing stream located in the Cook Inlet drainage of southcentral Alaska. Besides the large numbers of king salmon, the river also hosts large numbers of sea-run Dolly Varden, Chum Salmon and a small run of Pink Salmon. See also *List of rivers of Al ...
