Clear Lake (Maine)
Musquacook Stream is a tributary to the Allagash River in the North Maine Woods. The stream originates in a chain of lakes in Maine range 11 townships 10, 11 and 12. The flow sequence is from Clear Lake through Fifth Musquacook Lake into Fourth Musquacook Lake in Piscataquis County; and from Fourth Musquacook Lake through Third Musquacook Lake, Second Musquacook Lake, and First Musquacook Lake into the Allagash River Musquacook Deadwater in Aroostook County. First Musquacook Lake First Musquacook Lake is connected to Second Musquacook Lake by a short, broad thoroughfare which keeps both lakes at the same elevation. The first lake extends north from the thoroughfare to overflow into Musquacook Stream upstream of Horse Race Rapids. Searway Brook enters the east shore of the first lake. Summer dissolved oxygen concentrations are marginal below the thermocline, but lake trout and brook trout reach the first lake through the thoroughfare during cool weather. Second Musquacook Lak ...

Saint John River (Bay Of Fundy)
The Saint John River (french: Fleuve Saint-Jean; Maliseet-Passamaquoddy: ''Wolastoq'') is a long river that flows from Northern Maine into Canada, and runs south along the western side of New Brunswick, emptying into the Atlantic Ocean in the Bay of Fundy. Eastern Canada's longest river, its drainage basin is one of the largest on the east coast at about . A part of the border between New Brunswick and Maine follows 130 km (80 miles) of the river. A tributary forms 55 km (35 miles) of the border between Quebec and Maine. New Brunswick settlements through which it passes include, moving downstream, Edmundston, Fredericton, Oromocto, and Saint John. It is regulated by hydro-power dams at Mactaquac, Beechwood, and Grand Falls, New Brunswick. Hydronym Samuel de Champlain visited the mouth of the river on the feast day of John the Baptist in 1604 and renamed it the Rivière Saint-Jean or Saint John River in English.

Lake Trout
The lake trout (''Salvelinus namaycush'') is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, namaycush, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish. Those caught with dark coloration may be called ''mud hens''. Taxonomy It is the only member of the subgenus ''Cristovomer'', which is more derived than the subgenus '' Baione'' (the most basal clade of ''Salvelinus'', containing the brook trout (''S. fontinalis'') and silver trout (''S. agasizii'')) but still basal to the other members of ''Salvelinus''. Range From a zoogeographical perspective, lake trout have a relatively narrow distribution. They are native only to the northern parts of North America, principally Canada, but also Alaska and, to some extent, the northeastern United States. Lake trout have been wide ...

Rivers Of Aroostook County, Maine
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs ...

Lake Whitefish
The lake whitefish (''Coregonus clupeaformis'') is a species of freshwater whitefish from North America. Lake whitefish are found throughout much of Canada and parts of the northern United States, including all of the Great Lakes. The lake whitefish is sometimes referred to as a "humpback" fish due to the small size of the head in relation to the length of the body.Roland Sigurdson (2011Lake whitefishMinnesota Department of Natural Resources Species Profile. 19 April. 2012 It is a valuable commercial fish, and also occasionally taken by sport fishermen. Smoked, refrigerated, vacuum-packed lake whitefish fillets are available in North American grocery stores. Other vernacular names used for this fish include ''Otsego bass'', ''Sault whitefish'', ''gizzard fish'', ''common whitefish, eastern whitefish, Great Lakes whitefish, humpback whitefish, inland whitefish'' and ''whitefish''.

White Sucker
The white sucker (''Catostomus commersonii)'' is a species of freshwater cypriniform fish inhabiting the upper Midwest and Northeast in North America, but it is also found as far south as Georgia and as far west as New Mexico. The fish is commonly known as a "sucker" due to its fleshy, papillose lips that suck up organic matter and '' aufwuchs'' from the bottom of rivers and streams. Other common names for the white sucker include bay fish, brook sucker, common sucker, and mullet. The white sucker is often confused with the longnose sucker (''C. catostomus''), because they look very similar. Etymology The specific name, ''commersonii'', is in honor of French naturalist Philibert Commerson. Description The white sucker is a long, round-bodied fish with a dark green, grey, copper, brown, or black back and sides and a light underbelly. The fish also has typical features of primitive Cypriniformes fishes, such as a homocercal tail, cycloid scales, and dorsal, pectoral, and pelvic f ...

Fallfish
The fallfish (''Semotilus corporalis'') is a North American freshwater fish, a chub in the family Cyprinidae. The fallfish is the largest minnow species native to Eastern North America. Description Average specimens generally measure about in length, but individuals occasionally grow to with exceptional specimens of more than having been recorded. Juvenile fallfish have a dark stripe that runs down the center of their body. They are a silvery shade on the top and sides of the body, but have a white shading on the belly. Breeding males develop a pinkish tone on the opercular region, although the species does not develop bright breeding colors. Spawning males build stone nests, known as a redd, which form a prominent part of the bottom on many streams throughout the northeast. Spawning is communal with both males and females joining the nest builder. Distribution and habitat Fallfish are found in the northeastern United States and eastern Canada, where they inhabit clear strea ...

Hornpout
The brown bullhead (''Ameiurus nebulosus'') is a fish of the family Ictaluridae that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead (''Ameiurus melas'') and yellow bullhead (''Ameiurus natalis''). It was originally described as ''Pimelodus nebulosus'' by Charles Alexandre Lesueur in 1819, and is also referred to as ''Ictalurus nebulosus''. The brown bullhead is also widely known as the "mud pout", "horned pout", "hornpout", or simply "mud cat", a name also used with the other bullhead species. The brown bullhead is important as a clan symbol of the Ojibwe people. In their tradition, the bullhead or is one of six beings that came out of the sea to form the original clans. Appearance The brown bullhead grows to be approximately in length and is a darker brown-green dorsally, growing lighter green and yellow towards the ventral surface. The belly is off-white or cream, and the fish has no scales. Additionally, th ... [...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. It is native to Eastern North America in the United States and Canada, but has been introduced elsewhere in North America, as well as to Iceland, Europe, and Asia. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook charr, squaretail, brookie or mud trout, among others. A potamodromous population in Lake Superior, as well as an anadromous population in Maine, is known as coaster trout or, simply, as coasters. The brook trout is the state fish of nine U.S. states: Michigan, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Vermont, Virginia, and West Virginia, and the Provincial Fish of Nova Scotia in Canada.

Thermocline
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) in which temperature changes more drastically with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below. Depending largely on season, latitude, and turbulent mixing by wind, thermoclines may be a semi-permanent feature of the body of water in which they occur, or they may form temporarily in response to phenomena such as the radiative heating/cooling of surface water during the day/night. Factors that affect the depth and thickness of a thermocline include seasonal weather variations, latitude, and local environmental conditions, such as tides and currents. Oceans Most of the heat energy of the sunlight that strikes the Earth is absorbed in the first few centimeters at the ocean's surface, which ...

Allagash River
The Allagash River is a tributary of the Saint John River, approximately long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed June 22, 2011 in northern Maine in the United States. It drains in a remote and scenic area of wilderness in the Maine North Woods north of Mount Katahdin. The name "Allagash" comes from the Abenaki language, a dialect of the Algonquin languages, spoken by the Penobscot Tribe. The word, ''/walakéskʸihtəkʸ/'', means "bark stream". The Allagash issues from Churchill Lake (formerly known as Heron Lake) at Churchill Depot in northern Piscataquis County. In its natural state, it also drained Allagash, Chamberlain, and Telos lakes, but in the 1840s dams were built which diverted their drainage into the East Branch of the Penobscot River, to facilitate the shipping of logs south to coastal Maine. Lock Dam drains some water from Chamberlain Lake into the south end of Eagle Lake, which then flows o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...
