Lake Mills (Washington)
Lake Mills was a reservoir in Olympic National Park, Washington, United States, that existed from 1927 to 2012. It was formed by the Glines Canyon Dam on the Elwha River and was located about 13 miles from the mouth of the river on the Olympic Peninsula. The lake was formed in 1927 with the completion of the dam and after the lowland forest that occupied the river bottom was clear-cut. With no fish passage facilities, the dam blocked passage of anadromous Pacific Salmon from the upper 50+ miles of the Elwha watershed located within Olympic National Park. The Elwha Ecosystem Restoration project included the removal of the Glines Canyon Dam in 2014. The lake was fully drained by October 2012, leaving only sediment upstream of the former dam site. Olympic National Park crews are revegetating the area to speed up ecological restoration and improve the habitat for the return of the salmon. Lake Mills was a habitat for rainbow trout, bull trout, and Dolly Varden trout which used th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympic National Park
Olympic National Park is a national park of the United States located in Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west-side temperate rainforest, and the forests of the drier east side. Within the park there are three distinct ecosystems, including subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast. President Theodore Roosevelt originally designated the park as Mount Olympus National Monument on March 2, 1909. The monument was redesignated a national park by Congress and President Franklin D. Roosevelt on June 29, 1938. In 1976, Olympic National Park was designated by UNESCO as an International Biosphere Reserve, and in 1981 as a World Heritage Site. In 1988, Congress designated 95 percent of the park () as the Olympic Wilderness, which was renamed Daniel J. Evans Wilderness in honor of the former Washington state Governor and U.S. Senator Daniel J. Evans in 2017. During his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Salmon
''Oncorhynchus'', from Ancient Greek ὄγκος (''ónkos''), meaning "bend", and ῥύγχος (''rhúnkhos''), meaning "snout", is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and semelparity. The name of the genus is derived from Ancient Greek ὄγκος (''ónkos''), meaning "bend", and ῥύγχος (''rhúnkhos''), meaning "snout", in reference to the hooked secondary sexual characteristic — known as the kype — that the males develop on the lower jaw tip during mating season. Range Salmon and trout within ''Oncorhynchus'' are native to the tributaries of the North Pacific Ocean, with their native ranges extend from the Bering Sea coasts ...

Lakes Of Clallam County, Washington
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...

Reservoirs In Washington (state)
A reservoir (; ) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by creeks, rivers or rainwater that runs off the surrounding forested catchments, or '' off-stream reservoirs'', which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Dolly Varden Trout
The Dolly Varden trout (''Salvelinus malma'') is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout" (which typically refers to freshwater species from the genera ''Salmo'' and ''Oncorhynchus''), it belongs to the genus ''Salvelinus'' (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the ''Salvelinus alpinus'' (Arctic char) complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap. Taxonomy The scientific name of the Dolly Varden is ''Salvelinus malma''. The species was originally named by German naturalist and taxonomist Johann Julius Walbaum in 1792 based on type specimens from the Kamchatka Peninsula in Siberia. The name '' ...

Bull Trout
The bull trout (''Salvelinus confluentus'') is a char of the family Salmonidae native to northwestern North America. Historically, ''S. confluentus'' has been known as the " Dolly Varden" (''S. malma''), but was reclassified as a separate species in 1980. Populations of bull trout in the lower 48 states are listed as threatened under the U.S. Endangered Species Act, and bull trout overall are listed as vulnerable to extinction on the IUCN Red List of Threatened Species. The Saskatchewan-Nelson Rivers population in Alberta, Canada is listed as threatened under the Species at Risk Act. Description Like other species of char, the fins of a bull trout have white leading edges. Its head and mouth are unusually large for salmonids, giving it its name. Bull trout have been recorded measuring up to in length and weighing . Bull trout may be either migratory, moving throughout large river systems, lakes, and the ocean, or they may be resident, remaining in the same stream their entir ...

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. Introductions to locations outside their nativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Restoration
Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed or transformed. It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures. Ecological restoration can help to reverse biodiversity loss, combat climate change, support the provision of ecosystem services and support local economies. The United Nations has named 2021–2030 the Decade on Ecosystem Restoration. Habitat restoration involves the deliberate rehabilitation of a specific area to reestablish a functional ecosystem. This may differ from historical baselines (the ecosystem's original condition at a particular point in time). To achieve successful habitat restoration, it is essential to understand the life cycles and interactions of species, as well as the essential elements such as food, water, nutrients, space, and shelter needed to supp ...

Elwha Ecosystem Restoration
The Elwha Ecosystem Restoration Project is a 21st-century project of the U.S. National Park Service to remove two dams on the Elwha River on the Olympic Peninsula in Washington (U.S. state), Washington state, and restore the river to a natural state. Until 2024, it was the largest dam removal project in history and it is the second largest ecosystem restoration project in the history of the National Park Service, after the Restoration of the Everglades. The controversial project, costing about $351.4 million, has been contested and periodically blocked for decades. It has been supported by a major collaboration among the Lower Elwha Klallam Tribe, environmental organizations, and federal and state agencies. The removal of the first of the two dams, the Elwha Dam, began in September 2011 and was completed ahead of schedule in March 2012. Removal of the second dam, the Glines Canyon Dam, was completed on August 26, 2014. History of the Elwha River Historically, the Elwha River wa ...

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different areas at different times of the year. The migratory ...
