In 2010, the lake was taken over by Coimbatore Corporation on a 90-year lease from the Public Works Department of the Government of Tamil Nadu. Hydrography The lake is fed by canals derived from Noyyal river. The lake also receives water from Selvachinthamani lake located upstream in the north and drain water. The lake has an outlet connecting it with Valankulam lake. The water can be released through four sluice gates located on the south side of the lake.

Eutrophication
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients deriv ...

List Of Chief Ministers Of Tamil Nadu
The chief minister of Tamil Nadu is the chief executive of the Indian state of Tamil Nadu. In accordance with the Constitution of India, the governor is a state's ''de jure'' head, but ''de facto'' executive authority rests with the chief minister. Following elections to the Tamil Nadu Legislative Assembly, the state's governor usually invites the party (or coalition) with a majority of seats to form the government. The governor appoints the chief minister, who is accountable to the assembly through his council of ministers. Given that he has the confidence of the assembly, the chief minister's term is for five years and is subject to no term limits. Since 1952, Tamil Nadu has had 12 chief ministers. The longest-serving chief minister, M. Karunanidhi from Dravida Munnetra Kazhagam held the office for over eighteen years in multiple tenures, while he was the one who had the largest gap between two terms (nearly thirteen years). The All India Anna Dravida Munn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans ( shrimp/ lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms ( starfish/ sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations ( fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. Fishing has been an important part of human culture since hunter-gatherer times, and is one of the few food production activities that have persisted ...

Painted Stork
The painted stork (''Mycteria leucocephala'') is a large wading bird, wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink Flight feather#Tertials, tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. They nest colonially in trees, often along with other waterbirds. The only sounds they produce are weak moans or bill clattering at the nest. They are not bird migration, migratory and only make short distance movements in some parts of their range in response to changes in weather or food availability or for breeding. Like other storks, they are often seen soaring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Grebe
The little grebe (''Tachybaptus ruficollis''), also known as dabchick, is a member of the grebe family of water birds. The genus name is from Ancient Greek ''takhus'' "fast" and ''bapto'' "to sink under". The specific ''ruficollis'' is from Latin ''rufus'' "red" and Modern Latin ''-collis'', "-necked", itself derived from Latin ''collum'' "neck". At in length it is the smallest European member of its family. It is commonly found in open bodies of water across most of its range. Taxonomy The little grebe was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name ''Colymbus ruficollis''. The tricolored grebe was considered conspecific, with some taxonomic authorities still considering it so. There are six currently-recognized subspecies, separated principally by size and colouration. * ''T. r. ruficollis'' – (Pallas, 1764): nominate, found from Europe and western Russia south to North Africa * ''T. r. iraquensis'' – (Ticehurst, 1923): found ...

Avifauna
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

South-west Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in Atmosphere of Earth, atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the Wet season, rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the #Africa, West African, Asia–Australian, the North American monsoon, North American, and South American monsoons. The term was first Glossary of the British Raj, used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringi ...
