The Rudrasagar Lake falls in the Melaghar Block under Sonamura Sub-Division in the West Tripura District and at a separation of around 55 km from the state capital of Tripura. Geologically the lake is arranged in the middle of 23029' N and 900 01' E. It is Under the Jurisdiction of Department of Fisheries, Department of Tourism, and Department of Agriculture/Horticulture/Soil Conservation where Department of Fisheries, Government of Tripura is the administration expert of the lake.
As indicated by the Annual Report (2005-2006) of Ministry of Environment and Forest Govt. of India,
Rudrasagar Lake is recorded in the LIST OF WETLANDS IDENTIFIED UNDER NATIONAL WETLAND CONSERVATION Program and was specified in THE LIST OF WETLANDS OF INTERNATIONAL IMPORTANCE UNDER RAMSAR CONVENTION (INDIA). Rudrasagar Lake (Ramsar site no. 1572.) was distinguished as Ramsar site on 08/11/05 at the 'CoP' 09 (Conference of Parties) meeting held at Uganda amid 8-15 November, 2005. Secretary General, Convention on Wetlands, Ramsar site has announced and included Rudrasagar Lake as in the rundown of wetlands of International Importance. This endorsement has been imparted by service of condition and timberland, govt. of India on 29-02-2007.
Hydromorphologically, Rudrasagar Lake is a characteristic sedimentation repository, which gets spill out of three lasting streams to be specific, Noacherra, Durlavnaraya cherra and Kemtali cherra. In the wake of settling the dregs from the got stream, clear water releases into the waterway Gomati through a connective channel to be specific Kachigang. The lake bed has been shaped by sediment statement. All things considered no stone development is found with 50m is residue (Clay soil) and underneath arrangement is sandy. Encompassing hillocks are of delicate sedimentary development. Attributable to high precipitation (2500mm) and downstream geology, the wetland is frequently overflowed with 4-5 times yearly pinnacle, aiding groundwater revive. Lake water is new with unimportant contamination with a profundity fluctuates from 2 m to 9m. Vacillation in water level differs from EL 9m to 16m.The downstream territory of the lake is 750 ha with a temperature variety from 370C to 50C and precipitation amid May 15 to October 15. Terrains are claimed by the state with lasting water territories rented out to the subsistent anglers' agreeable, and encompassing occasional water bodies are developed for paddy.
The lake is rich in economically imperative freshwater angles like Botia spp, Notopterus Chitala, Mystus spp., Ompok pabda, Labeo bata, Mystus aor, Wallago attu, Heterophneutes fossilis and freshwater scampi, with yearly creation of 26 metric-tons, and a perfect natural surroundings for IUCN Redlisted Three-striped Roof Turtle Kachuga dhongka. Aside from these species other imperative fish species are: Puntius sophore, Esomus danrica, Chanda ranga, nandus, Anabus testudeneus, Colisa fasciatus, notopterus, Cirrhinus reba, Mastacembelus pancalus, Channa punctata,, Macrognathus siamensis, Gudusia chapra, Cylonia spp, Labeo rohita, Mystus gulio, Ompak paba, Channa marulius and so forth.
By and by the lake is progressively confronting a few anthropogenic weights which are undermining the environmental adjust of the lake. These issues are-
Eco-zoning of Lake Shoreline: Breaking the IUCN protection rules, the shoreline was exasperates with number of acts of neglect, for example, anthropogenic dumped trash, affidavit of strong waste and development materials along the shoreline and so forth.
Eutrophication: Uncontrolled development of outsider intrusive species, for example, water hyacinth, exorbitant green growth was seen in the lake which caused loss of oceanic biodiversity. Social Eutrophication which was seen, as it were, is thought to be the real parameter for poor water quality administration in Rudrasagar Lake.
Soil disintegration and Siltation in the lake: Major soil disintegration in catchment territory of the lake is one of the key issues to diminish the lake region and to diminish the profundity of the lake too. For such reason and others, the region of Rudrasagar Lake has been diminished radically from 1000 ha. Preceding 1950 to pretty much 100 ha. at present. Siltation is happening because of expanded disintegration because of development of human living space and farming regions, deforestation, surge, inundation of icons by the religious action and such other land unsettling influences occurring in the waste bowl of the lake.
Farming action: As the water region has been diminished, the general public used to use out the neighboring zone of the lake to the individuals for horticulture reason. Great quantities of rancher utilize pesticides and concoction manures in their paddy field which is pernicious to the living beings of the lake.
Deforestation, filling, depleting and corruption of wetland regions: Clearing and evacuation of local vegetation because of the fast impromptu formative movement in the lake zone isn't just lessening the local vegetation biodiversity, yet in addition diminishes fauna biodiversity through the loss of environment for rearing, settling, and sustaining and expanded rivalry for existing living space territories..
Absence of mindfulness, logical information and carelessness in assurance by law: Landowners of the encompassing territories don't know about protection parts of biodiversity on their territory. Because of absence of logical information, and the many-sided quality of environments, usually difficult to anticipate what impacts certain exercises will have on specific species or biological systems, or what factors are causing singular species decrease. Consistently amid November to April, people groups from various parts of the state and in addition from outside, visit the place for cookout reason. Be that as it may, it is astonishing to see the strong waste dumped by the outing parties in the lake shoreline and in addition in the lake water itself. Not in any case a solitary billboard or standard has been hanged in the regions by the concerned expert to secure and keep the lake to be defiled by these anthropogenic exercises. The wetland isn't having an unmistakable Wetland Authority as well.
