The state has vast processes that can form lakes. A potential & all its water bodies Glacial Lake: A lake with origins in recent tectonic uplift of a mountain needs to be preserved as many of a melted glacier such as Sheeshnag range can create bowl-shaped them are under the pressure of Lake located in District Anantnag. depressions that accumulate water pollution, encroachment, silting, and form lakes. The advance and Artificial Lake: A lake created by construction activity or retreat of glaciers can scrape flooding land behind a dam, called urbanization. They are the main depressions in the surface where an impoundment or reservoir, by flood basins around our cities. Our water accumulates, example of deliberate human excavation e.g., population depends on these for such lakes are Kousarnag, Tarsar, Harwan reservoir in Srinagar, drinking water, fishing, livelihood Marsar etc. Yusmarg reservoir in Budgam. etc. Flash floods in the month of September 2014 are an indicator Lakes can also form by means of Endorheic Lake: Example of such that our water bodies are not landslides or by glacial blockages type of lake is Tsomorori in being managed properly and we such as Gangabal, Kishansar, Ladakh. Such lakes are most need to restore their glory for the Vishansar and Nagputan lakes common in desert locations. future generations. located in Ganderbal District.

Apart from being most valuable natural habitat for a number of Flora Oxbow Lake: A lake which is formed when a wide and Fauna, these water bodies are also life line for a meander from a stream or a river is cut off to form a large number of people and act as part of vital lake. They are called "oxbow" lakes due to the hydrological cycle. distinctive curved shape that results from this As the state is well known for its charming scenery, process. e.g., Hokarsar, Haigam located in Baramulla comprising beautiful springs, lakes, rivers and their etc tributaries, all these add to its scenic beauty. As per data prepared by Department of Ecology, Rift Lake or Sag pond: A lake which forms as a Environment & Remote Sensing, J&K, there are 1230 result of subsidence along a geological fault in the lakes and water bodies in the state with 150 in Earth's tectonic plates. Examples include the Jammu region, 415 in Kashmir region and 665 in Tsomorori and Pangong lakes in Ladakh. Ladakh. On the basis of altitudes these have been divided into two categories. Underground Lake: A lake which is formed under the surface of the Earth's crust. Such a lake may be High Altitude Lakes: Gangabal, Vishan Sar, Kishan associated with caves, aquifers or springs. Sar, Sheesh Nag, Nilnag, Kausarnag etc. Crater Lake: A lake which forms in a Valley Lakes: Wular, Dal, Manasbal, Aanchar, volcanic caldera or crater after the volcano has been Ahansar, Hokersar, Haigam etc. inactive for some time. Water in this type of lake may be fresh or highly acidic, and may contain various dissolved minerals. Some also have geothermal activity, especially if the volcano is merely dormant rather than extinct. Lava Lake: A pool of molten lava contained in a volcanic crater or other depression. Lava lakes that have partly or completely solidified are also referred to as lava lakes. Former: A lake which is no longer in existence. Bodsar is an example of a former lake. Gangabal Lake Ephemeral Lake: A seasonal lake that exists as Classification of Water bodies as per a body of water during only part of the year. Wetland Land rules 2010 of Ministry of Intermittent Lake: A lake with no water during a Environment and Forests part of the year. The classification of Wetlands as per the Wetlands Rules 2010, as finalized by Ministry of Environment Shrunken: Examples are Barinambal, Kushhalsar, and Forests Govt. of India is as follows: Anchar, Gilsar located in Srinagar and Hokarsar, Haigam in Baramulla. “The classification system besides all the wetlands incorporates Reservoirs, Ash ponds/Cooling ponds, and abandoned Quarries.” 3 The Ministry of Environment and Forests has notified Table 3: Area wise number of Lakes/Water bodies of the Wetlands (Conservation and Management) Rules, different districts (Old) Kashmir Division 2010.
