Geographically the lake is positioned in between 23029 'N and 900 01' E. It’s Beneath the Jurisdiction of Division of Fisheries, Division of Tourism, and Division of Agriculture / Horticulture / Soil Conservation the place Division of Fisheries, Authorities of Tripura is the administration authority of the lake.

In keeping with the Annual Report (2005-2006) of Ministry of Setting and Forest Govt. of India,
Rudrasagar Lake is listed in the LIST OF WETLANDS IDENTIFIED UNDER NATIONAL WETLAND CONSERVATION PROGRAM and was said in THE LIST OF WETLANDS OF INTERNATIONAL IMPORTANCE UNDER RAMSAR CONVENTION (INDIA). Rudrasagar Lake (Ramsar website no. 1572.) was recognized as Ramsar website on 08/11/05 on the 'CoP' 09 (Convention of Events) assembly held at Uganda throughout Eight-15 November, 2005. Secretary Common, Conference on Wetlands , Ramsar website has declared and included Rudrasagar Lake as in the listing of wetlands of International Importance. This certificates has been communicated by ministry of atmosphere and forest, govt. of India on 29-02-2007.

Hydromorphologically, Rudrasagar Lake is a pure sedimentation reservoir, which receives circulate from three perennial streams specifically, Noacherra, Durlavnaraya cherra and Kemtali cherra. After settling the sediment from the obtained circulate, clear water discharges into the river Gomati by means of a connective channel specifically Kachigang. The lake mattress has been fashioned by silt deposition. As such no rock formation is discovered with 50m is silt (Clay loam) and under formation is sandy. Surrounding hills are of tender sedimentary formation. Owing to excessive rainfall (2500mm) and downstream topography, the wetland is repeatedly flooded with four-5 instances annual peak, helping in groundwater recharge. Lake water is contemporary with insignificant air pollution with a depth varies from 2 m to 9m. Fluctuation in water stage variants from EL 9m to 16m.The downstream space of ​​the lake is 750 ha with a temperature variation from 370C to 50C and wet throughout Might 15 to October 15. Lands are owned by the state with perennial water areas leased out to the constant fisherman's cooperative, and surrounding seasonal water our bodies are cultured for paddy.

The lake is abundantly in commercially vital freshwater fishes like Botia spp, Notopterus Chitala, Mystus spp., Ompok pabda, Labeo bata, Mystus aor, Wallago attu, Heterophneutes fossilis and freshwater scampi, with annual manufacturing of 26 metric-tons, and a really perfect habitat for IUCN Redlisted Three-striped Roof Turtle Kachuga dhongka. Aside from these species different vital fish species 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 and many others.

At present the lake is more and more dealing with a number of anthropogenic pressures that are threatening the ecological stability of the lake. These issues are-

Eco-zoning of Lake Shoreline : Breaking the IUCN conservation pointers, the shoreline was disturbed with quantity of malpractices comparable to anthropogenic dumped rubbish, deposition of strong waste and building supplies alongside the shoreline and many others.

Eutrophication : Uncontrolled progress of alien invasive species comparable to water hyacinth, extreme algae was noticed in the lake which brought on loss of aquatic biodiversity. Cultural Eutrophication which was noticed to an important extent is taken into account to be the main parameter for poor water high quality administration in Rudrasagar Lake.

Soil erosion and Siltation in the lake : Main soil erosion in catchment space of ​​the lake is one of the important thing issues to lower the lake space and to lower the depth of the lake additionally.

Siltation is happening resulting from elevated erosion because of this of enlargement of human habitat and agricultural areas, deforestation, flood, immersion of idols by the spiritual exercise and such different land disturbances happening in the drain basin of the lake.

Agricultural exercise : Because the water space has been decreed, the society used to make use of out the adjoining space of ​​the lake to the members for agriculture function. Good numbers of farmer use pesticides and chemical fertilizers in their paddy area which is deleterious to the dwelling organizations of the lake.

Deforestation, filling, draining and degradation of wetland areas : Clearing and elimination of native vegetation as a result of speedy unplanned developmental exercise in the lake space isn’t solely lowering the native vegetation biodiversity, but additionally reduces fauna biodiversity by means of the loss of habitat for breeding, nesting, and feeding and elevated competitors for current habitat areas ..

Lack of consciousness, scientific data and negligence in safety by legislation : Landowners of the encircling areas are usually not aware of conservation facets of biodiversity on their land. On account of lack of scientific data, and the complexity of ecosystems, it’s usually tough to foretell what impacts sure actions may have on sure species or ecosystems, or what elements are inflicting particular person species decline. Yearly throughout November to April, peoples from totally different components of the state in addition to from outdoors, go to the place for picnic function. However it’s shocking to see the strong waste dumped by the picnic events in the lake shoreline in addition to in the lake water itself. Not even a single signboard or banner has been hung in the areas by the involved authority to guard and forestall the lake to be contaminated by these anthropogenic actions.

Nevertheless growth of tourism has been unplanned and spontaneous. The optimum nature of the current useful resource appropriation in gentle of its sustainability must be labored out by means of additional ecological assessments and particular regulatory framework needs to be in place to revive the ecological stability of the ecosystem.
