Słupca Lake
Słupca Lake () is an artificial reservoir located in Wielkopolska Province in central–western Poland. It was created in 1955 as a recreational centre on former turbary land. It has a surface of 258 hectares, with 0.9 km breadth and length of 3.6 km. The lake, fed by the Meszna River, is situated at the edge of Słupca town, and has long been the site of urban development. From the south, the lake borders on Słupca Town Park, with the amphitheater, shooting range and two stadiums. In recent time, thanks to significant improvement of the community's economy driven mainly by the proximity of the city of Poznań, the lake is getting surrounded by cottages and dwellings of the new upper-middle class. Tourism activities In the past, the Lake was a site of motor-boat races, and a popular active-tourism destination. Among sports practiced there one could find canoeing, surfing, swimming, and sailing among others. Underwater sports such as scuba diving or snorkeling were nev ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, 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 Bay, 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 stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Human Swimming
Swimming is the self-propulsion of a person through water, such as saltwater or freshwater environments, usually for recreation, sport, exercise, or survival. Swimmers achieve locomotion by coordinating limb and body movements to achieve hydrodynamic thrust that results in directional motion. Newborns can instinctively hold their breath underwater and exhibit rudimentary swimming movements as part of a survival reflex. Swimming requires endurance, skill and efficient techniques to maximize speed and minimize energy consumption. Swimming is a popular activity and competitive sport where certain techniques are deployed to move through water. It offers numerous health benefits, such as strengthened cardiovascular health, muscle strength, and increased flexibility. It is suitable for people of all ages and fitness levels. Swimming is consistently among the top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum ...

Rutilus
''Rutilus'', commonly known as roaches, is a genus of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related fishes. This genus is a widely distributed lineage of leuciscids and ranges from West Europe to East Siberia. Taxonomy ''Rutilus'' was first proposed as a genus in 1820 by the French polymath Constantine Samuel Rafinesque with ''Cyprinus rutilus'' designated as the type species but also the type species by absolute tautonymy. ''Cyprinus rutilus'' was first formally described in the 10th edition of ''Systema Naturae'' by Carl Linnaeus with "European lakes" given as the type locality. In a phylogeographic study, Levin et al. (2017) argue that the Ponto-Caspian taxa including ''R. caspicus'', ''R. heckelii'' and ''R. stoumboudae'' could represent a single widespread species whose range extends to Siberia, to be named ''Rutilus lacustris'', whereas ''R. kutum'' is included in ''R. frisii''.

Perch
Perch is a common name for freshwater fish from the genus ''Perca'', which belongs to the family Percidae of the large order Perciformes. The name comes from , meaning the type species of this genus, the European perch (''P. fluviatilis''). Many species of freshwater game fish more or less resemble perch, but belong to different genera. In fact, the exclusively saltwater-dwelling red drum (which belong to a different order Acanthuriformes) is often referred to as a "red perch", though by definition perch are freshwater species. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. Species Most authorities recognize three species within the perch genus: * The European perch (''P. fluviatilis'') is primarily found in Europe, but a few can also be found in South Africa, and even as far east on the Southern hemisphere as Australia. This species is typically greenish in color with dark vertical ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carp
The term carp (: carp) is a generic common name for numerous species of freshwater fish from the family (biology), family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized game fish, quarries and are valued (even pisciculture, commercially cultivated) as both food fish, food and ornamental fish in many parts of the Old World, they are considered trash fish and invasive species, invasive pest (organism), pests in many parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angling
Angling (from Old English ''angol'', meaning "hook") is a fishing technique that uses a fish hook attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated with a fishing rod, although rodless techniques such as handlining also exist. Modern angling rods are usually fitted with a fishing reel that functions as a crank (mechanism), cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and traditional cane pole fishing are two rod-angling methods that do not use any reel. The fish hook itself can be additionally weighted with a denser fishing tackle, tackle called a sinker (fishing), sinker, and is typically dressed with an appetizing bait (luring substance), bait (i.e. hookbait) to attract and entice the fish into swallowing the hook, but sometimes an inedible fake/imitation bait with multiple attached hooks (known as a fishing lure, lure) is used instead of a single hook with edible bait.

Snorkeling
Snorkeling (American and British English spelling differences#Doubled in British English, British and Commonwealth English spelling: snorkelling) is the practice of human swimming, swimming face down on or through a body of water while breathing the ambient air through a shaped tube called a Snorkel (swimming), snorkel, usually with swimming goggles or a diving mask, and swimfins. In cooler waters, a wetsuit may also be worn. The snorkel may be an independent item or integrated with the mask. The use of this equipment allows the snorkeler to observe the underwater environment for extended periods with relatively little effort, and to breathe while face-down at the surface. Snorkeling is a popular recreational activity, particularly at tropics, tropical resort locations. It provides the opportunity to observe marine biology#Lifeforms, underwater life in a natural setting without the complicated equipment and training required for scuba diving. It appeals to all ages because of ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailing
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, Windsurfing, windsurfer, or Kitesurfing, kitesurfer), on ''ice'' (iceboat) or on ''land'' (Land sailing, land yacht) over a chosen Course (navigation), course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail. Sail was slowly replaced by steam as the method of propulsion for ships over the latter part of the 19th century – seeing a gradual improvement in the technology of steam through a number of developmental steps. Steam allowed schedul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surfing
Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found as standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or wave pools. Surfing includes all forms of wave-riding using a board, regardless of the stance. There are several types of boards. The Moche of Peru would often surf on reed craft, while the native peoples of the Pacific surfed waves on alaia, paipo, and other such watercraft. Ancient cultures often surfed on their belly and knees, while modern-day surfing is most often ''stand-up surfing'', in which a surfer rides a wave while standing on a surfboard. Another prominent form of surfing is body boarding, where a surfer rides the wave on a bodyboard, either lying on thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canoeing
Canoeing is an activity which involves paddling a canoe with a single-bladed paddle. In some parts of Europe, canoeing refers to both canoeing and kayaking, with a canoe being called an 'open canoe' or Canadian. A few of the recreational forms of canoeing are canoe camping and canoe racing. Other forms include a wide range of canoeing on lakes, rivers, oceans, ponds and streams. History of organized recreational canoeing Canoeing is an ancient mode of transportation. Modern recreational canoeing was established in the late 19th century. Among early promoters of canoeing as a sport was Carl Smith, who introduced canoeing to Sweden in the 1880s. In 1924, canoeing associations from Austria, Germany, Denmark, and Sweden founded the ''Internationalen Representation for Kanusport'', the forerunner of the International Canoe Federation (ICF). Canoeing became part of the Olympic Games in the 1936 Summer Olympics. which featured canoe sprint Canoe sprint is a wat ...
