The Rudrasagar Lake falls within the Melaghar Block under Sonamura Sub-Division inside the western world Tripura District and away of roughly 55 km inside the condition capital of Tripura. Geographically the forest are available in between 23029′ N and 900 01′ E. It’s Underneath the Jurisdiction of Department of Fisheries, Department of Tourism, and Department of Agriculture/Horticulture/Soil Conservation where Department of Fisheries, Government of Tripura may be the management authority within the lake.
Using the Annual Report (2005-2006) of Secretary of condition for Atmosphere and Forest Govt. asia,
Rudrasagar Lake appears within the Set Of WETLANDS IDENTIFIED UNDER NATIONAL WETLAND CONSERVATION PROGRAMME plus it was mentioned within the Set Of WETLANDS OF Worldwide IMPORTANCE UNDER RAMSAR CONVENTION (INDIA). Rudrasagar Lake (Ramsar site no. 1572.) was known as Ramsar site on 08/11/05 inside the ‘CoP’ 09 (Conference of Parties) meeting held at Uganda during 8-15 November, 2005. Secretary General, Convention on Wetlands, Ramsar site has declared and incorporated Rudrasagar Lake much like their list of wetlands of Worldwide Importance. This certificate remains conveyed by secretary of condition for atmosphere and forest, govt. asia on 29-02-2007.
Hydromorphologically, Rudrasagar Lake could be a natural sedimentation reservoir, which receives flow from three perennial streams namely, Noacherra, Durlavnaraya cherra and Kemtali cherra. After settling the sediment inside the received flow, apparent water discharges towards the river Gomati utilizing a connective funnel namely Kachigang. The forest bed remains created by silt deposition. Consequently no rock formation can be found with 50m is silt (Clay loam) and below formation is sandy. Surrounding hillocks have soft sedimentary formation. Because of high rain (2500mm) and downstream topography, the wetland is frequently flooded with 4-5 occasions annual peak, assisting in groundwater recharge. Lake water is fresh with minor pollution obtaining a depth differs from 2 m to 9m. Fluctuation in level differs from EL 9m to 16m.The downstream part of the lake is 750 ha obtaining a temperature variation from 370C to 50C and rain during May 15 to October 15. Lands participate in the issue with perennial water areas leased for the subsistent fishermen’s cooperative, and surrounding periodic water physiques are cultivated for paddy.
The forest is wealthy in commercially important freshwater fishes like Botia spp, Notopterus Chitala, Mystus spp., Ompok pabda, Labeo bata, Mystus aor, Wallago attu, Heterophneutes fossilis and freshwater scampi, with annual creation of 26 metric-tons, along with an ideal habitat for IUCN Redlisted Three-striped Roof Turtle Kachuga dhongka. Aside from these species other important striper are: Puntius sophore, Esomus danrica, Chanda ranga, Nandus nandus, Anabus testudeneus, Colisa fasciatus, Notopterus notopterus, Cirrhinus reba, Mastacembelus pancalus, Channa punctata,, Macrognathus siamensis, Gudusia chapra, Cylonia spp, Labeo rohita, Mystus gulio, Ompak paba, Channa marulius etc.
Presently the forest is more and more more facing several anthropogenic pressures that are threatening the environmental balance within the lake. These problems are-
Eco-zoning of Lake Shoreline: Damaging the IUCN conservation guidelines, the shoreline was disturbed with amount of malpractices for example anthropogenic dumped garbage, deposition of solid waste and construction materials within the shoreline etc.
Eutrophication: Unmanageable progression of alien invasive species for example water hyacinth, excessive algae was observed inside the river which caused inadequate marine bio-diversity. Cultural Eutrophication that was observed having a degree is recognized as since the primary parameter for poor water quality management in Rudrasagar Lake.
Soil erosion and Siltation within the lake: Major soil erosion in catchment part of the lake is most likely the important thing problems to lessen the forest area and to decrease the depth within the lake also. For such reason while some, the place of Rudrasagar Lake remains decreased drastically from 1000 ha. Before 1950 to virtually 100 ha. at this time. Siltation is happening because of elevated erosion because of growth and development of human habitat and farming areas, deforestation, ton, immersion of idols using the religious activity and so forth other land disturbances happening within the drainage basin within the lake.
