Lake Matka
Matka is the oldest artificial lake in Macedonia, with its reservoir being built in 1938. It was created by damming the Treska River with the dam of St. Andrew (dam), St. Andrew and forming an artificial reservoir in the Matka Canyon. The water from the lake is used for hydroelectric power generation as well as irrigation of the surrounding villages. The lake is also stocked with fish and is frequently used for recreational fishing. Within the lake, there is the underwater cave called Vrelo, one of the deepest underwater caves in Europe, with a depth of over .

Artificial Lake
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 larg ...

Treska
Treska (; ), is a river in the western part of North Macedonia, flowing for before joining the Vardar as its right tributary. With a basin covering 2,068 km2, the river originates high in the Stogovo mountain at about 2,000 metres elevation, initially flowing eastward through the Kičevo valley before making a sharp northward turn near Makedonski Brod and continuing through a narrow valley between the Suva Gora and Karadžica mountains to eventually meet the Vardar river near Skopje. The river system is known for its three major dams—Matka (built in 1937), Kozjak (2004), and Sveta Petka (2012)—as well as its diverse groundwater resources, which include isotropic aquifers in river valleys, fractured aquifers in mountainous regions, and particularly significant karst aquifers in limestone-rich areas that supply water to several towns in North Macedonia despite facing contamination risks from inadequate sewage infrastructure, unsanctioned landfills, intensive agriculture, a ...

Matka Canyon
Matka (; ) is a canyon located west of central Skopje, North Macedonia. Covering roughly 5,000 hectares, Matka is one of the most popular outdoor destinations in North Macedonia and is home to several medieval monasteries. The Matka Lake within the Matka Canyon is the oldest artificial lake in the country. Geology There are ten caves at Matka Canyon, with the shortest in length being 20 metres (65.6 feet) and the longest being 176 metres (577.4 feet). The canyon also features two vertical pits, both roughly extending 35 metres (114.8 feet) in depth. Vrelo Cave Located on the right bank of the Treska River, Vrelo Cave was listed as one of the top 77 natural sites in the world in the New7Wonders of Nature project. Vrelo Cave has many stalactites including a large one in the middle of the cave known as the "Pine Cone" due to its shape. There are two lakes at the end of the cave, with one larger than the other. The smaller lake is 8 metres (26.2 feet) at its longest length and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Recreational Fishing
Recreational fishing, also called sport fishing or game fishing, is fishing for leisure, exercise or competition. It can be contrasted with commercial fishing, which is occupational fishing activities done for profit; or subsistence fishing, which is fishing for survival and livelihood. The most common form of recreational fishing is angling, which is done with a rig of rod, reel, line, hooks and any one of a wide range of baits, as well as other complementary devices such as weights, floats, swivels and method feeders, collectively referred to as '' terminal tackles''. Lures are frequently used instead of fresh bait when fishing for predatory fishes. Some hobbyists hand-make custom tackles themselves, including plastic lures and artificial flies. Other forms of recreational fishing include spearfishing, which is done with a speargun or harpoon usually while diving; and bowfishing, which is done from above the water with archery equipments such as a co ...

Underwater Cave
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
