Briar Creek Reservoir
The Briar Creek Reservoir (also known as Briar Creek Park Lake or Briar Creek Lake) is a reservoir in Columbia County, Pennsylvania, in the United States. It has an area of 51.04 acres and is located in Briar Creek Township, Columbia County, Pennsylvania, Briar Creek Township. The lake is situated on East Branch Briar Creek. The lake was constructed in the early 1970s for the purpose of flood control. It is dammed by the Briar Creek Dam. Shale and limestone rocks are found in the lake's vicinity. The lake was electrofished by the Pennsylvania Fish and Boat Commission in 2010. The reservoir is designated as Approved Trout Waters and is stocked with trout. More than a dozen species of fish inhabit it and several bird species are found in its vicinity. The lake is part of the 173-acre Briar Creek Lake Park. Fishing and boating are done in the reservoir.

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climate cha ...

Bluegill
The bluegill (''Lepomis macrochirus''), sometimes referred to as "bream", "brim", "sunny", or "copper nose" as is common in Texas, is a species of North American freshwater fish, native to and commonly found in streams, rivers, lakes, ponds and wetlands east of the Rocky Mountains. It is the type species of the genus ''Lepomis'' (true sunfish), from the family Centrarchidae (sunfishes, crappies and black basses) in the order Perciformes (perch-like fish). Bluegills can grow up to long and about . While their color can vary from population to population, they typically have a very distinctive coloring, with deep blue and purple on the face and gill cover, dark olive-colored bands down the side, and a fiery orange to yellow belly. They are omnivorous and will consume anything they can fit in their mouth, but mostly feed on small aquatic insects and baitfishes. The fish are important prey for bass, other larger sunfish, northern pike and muskellunge, walleye, trout, herons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hatchery
A hatchery is a facility where eggs are hatched under artificial conditions, especially those of fish, poultry or even turtles. It may be used for ex-situ conservation purposes, i.e. to breed rare or endangered species under controlled conditions; alternatively, it may be for economic reasons (i.e. to enhance food supplies or fishery resources). Fish hatcheries Fish hatcheries are used to cultivate and breed a large number of fish in an enclosed environment. Fish farms use hatcheries to cultivate fish to sell for food, or ornamental purposes, eliminating the need to find the fish in the wild and even providing some species outside their natural season. They raise the fish until they are ready to be eaten or sold to aquarium stores. Other hatcheries release the juvenile fish into a river, lake or the ocean to support commercial, tribal, or recreational fishing or to supplement the natural numbers of threatened or endangered species, a practice known as fish stocking.

White Crappie
The white crappie (''Pomoxis annularis'') is a freshwater fish found in North America, one of the two species of crappies. Alternate common names for the species include goldring and silver perch. is named for the fish. The genus name ''Pomoxis'' refers to crappies' sharp operculum, while the species name ''annularis'' means 'having rings', i.e., it has vaguely vertical bars on the body. Description White crappies are morphologically similar to black crappie. They have 5–10 dark vertical bars along their bodies, rather than the randomly scattered spots like the black crappie. The white crappie has a silvery color with green or brown shades along its back, with dark lateral bars along its side, and a white belly. The dorsal fins of the white crappie starts farther back on the body than those of the black crappie. The anal fin is about the same size as the dorsal fin. The white crappie has six dorsal fin spines, whereas the black crappie has seven or eight dorsal fin spines. W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Shiner
The golden shiner (''Notemigonus crysoleucas'') is a cyprinid fish native to eastern North America. It is the sole member of its genus. Much used as a bait fish, it is probably the most widely pond-cultured fish in the United States. It can be found in Quebec, and its French name is "Mené jaune" or "Chatte de l'Est". Taxonomy It is the only North American member of the Old World clade within subfamily Leuciscinae. Description Though it has been known to reach lengths of , in the wild the golden shiner is usually between long. The body is laterally compressed (deep-bodied). The back is dark green or olive, and the belly is a silvery white. The sides are silver in smaller individuals, but golden in larger ones. There can be a faint dusky stripe along the sides. The anal fin is large and has 8-19 rays, while the dorsal fin comprises almost always 8 rays. Scales are relatively large and easily lost when the fish is handled. The mouth is small and upturned. Two characteristics can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Bullhead
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] |
Yellow Perch
The yellow perch (''Perca flavescens''), commonly referred to as perch, striped perch, American perch, American river perch or preacher is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. It is closely related, and morphologically similar to the European perch (''Perca fluviatilis''); and is sometimes considered a subspecies of its European counterpart. Other common names for yellow perch include American perch, coontail, lake perch, raccoon perch, ring-tail perch, ringed perch, and striped perch. Another nickname for the perch is the Dodd fish. Latitudinal variability in age, growth rates, and size have been observed among populations of yellow perch, likely resulting from differences in day length and annual water temperatures. In many populations, yellow perch often live 9 to 10 years, with adults generally ranging from in length. The world record yellow perch (; ) was caught in May 1 ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Stocking
Fish stocking is the practice of raising fish in a hatchery and releasing them into a river, lake or ocean to supplement existing populations or to create a population where previously none exists. Stocking may be done for the benefit of commercial, recreational or tribal heritage fishing, but may also be done to restore or increase the population of threatened or endangered fish in a body of water closed to fishing. Fish stocking may be conducted by governmental agencies in public waters, or by private groups in private waters. When in public waters, fish stocking creates a common-pool resource which is rivalrous in nature but non-excludable. Thus, on public grounds, all can enjoy the benefits of fishing so long as fish continue to be stocked. History Fish stocking is a practice that dates back hundreds of years. According to biologist Edwin Pister, widespread trout stocking dates back to the 1800s. For the first hundred years of stocking, the location and number of fish introdu ...

Electrofishing
Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned."FISHNET SHOCKINGS" . ''Toronto Star'', December 3, page IN3. Paul Hunter Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, density and species composition. When performed correctly, electrofishing results in no permanent harm to the fish, which return to their natural mobility state in as little as two minutes after being caught. Method Electrofishing relies on two |
