Manasbal Lake
Manasbal Lake is the deepest freshwater lake found in the Safapora area of Ganderbal district of Jammu and [Kashmir (union territory)|Jammu and Kashmir], India. Named after the sacred Manasarovar. The lake is encircled by four villages, viz., Jarokbal, Kondabal, Nesbal, and Gratbal. It's renowned for its lotus blooms at the periphery of the lake adds to the beauty of the clear waters of the lake. The Mughal garden, called the Jaroka Bagh, built by Nur Jahan, overlooks the lake.
The lake is a good place for birdwatching as it is one of the largest natural spawning grounds of Aquatic birds in Kashmir and has the epithet "supreme gem of all Kashmir Lakes". The rootstocks of the lotus plant, which grows extensively in the lake, are harvested and marketed, and also eaten by the local people.
Access
The lake is approached from Srinagar by a road via Shadipora, Nasim, and Ganderbal. The road to Wular Lake, the largest lake in Kashmir, passes through this lake via Safapora.It is also easy to reach Manasbal from Sonmarg via Ganderbal.
History
It is believed to be an ancient lake by locals, but exact dating is yet to be done. Close to the northern shore of the lake are the ruins of a 17th-century fort, called the Jharokha Bagh, built by the Mughals, used in the past by caravans traveling from Punjab to Kashmir.Topography
The lake is surrounded by the Baladar mountains on the east, by an elevated plateau known as 'Karewa' comprising lacustrine, fluviatile, and loessic deposits on the north, and bounded by the Ahtung hills in the south, which are used for limestone extraction.Along the course of the Jhelum River, the Manasbal Lake falls under the third series of high altitude lakes of the Himalayas as the valley lakes situated at the altitudinal zone of ; the other two types being the high altitude wetlands of the second series of lakes in the lower fringes of Pir Panjal ranges right amid pine forests, and the glaciated lakes of the first series situated on the inner Himalayas between amsl which have probably originated during the third Himalayan glaciation. A fissure is reported to be running from east to west at the centre of the lake.
Land use
Important vegetation in the catchment of the lake comprises Orchards, some Platanus, and Salix trees. Safar, adjacent to Safapur, contains an extensive grove of Chinar trees, known as Badshah Boni, royal Chinar, and was planted in imitation of the Nasim Bagh in Srinagar. Maize, mustard, and wheat are generally the main crops grown in the agricultural lands of the catchment. In recent years, land use patterns have changed with more land used for horticulture and also diversion of land for construction purposes.Hydrology
The drainage basin for the lake, covering an area of, has no major inlet channels and is thus fed mainly by precipitation and springs. Lake water outflows to the Jhelum River through a regulated outflow channel. The lake is the source of water for fishing and for obtaining food and fodder plants.The lake not only provides a source of water but also offers facilities for navigation and transportation, fisheries, harvesting of economically useful plants, sightseeing, tourism, and recreation.
Water quality issues
Some of the water quality parameters reported relate to:- The lake is a monomictic mixing type and develops thermal stratification from March to November. The maximum depth of the Thermocline is. Hypolimnion temperature ranges from to.
- pH value varied from a maximum of 8.8 on the surface to a minimum of 7.7 at depth in year over the 12 months.
- DO value varied from a maximum of 10.4 on the surface to a minimum of 2.2 at the bottom in year over the 12 months.
- Maximum Nitrogen Concentration (NH4-N of 13 on the surface and 120 at the bottom of the lake has been reported.
- The lake water temperature varied from a minimum of in January to in June/July at the surface and correspondingly and, at the bottom of the lake.
Flora
Within the lake water, the flora recorded comprises the following.- Emerged macrophytes, floating macrophytes, submerged macrophytes, and phytoplankton. In the reported period, the biomass production due to plankton was a maximum of 864.9 milligrams/cm2 in June, with a minimum of 54 milligrams/cm2 in December.
Fauna
The fauna recorded in the lake includes zooplankton, benthos, and fish. The economically important fishes reported are:- Schizothorax niger, S. esocinus, Cyprinus carpio specularis+, C. carpio communis+ and Neomacheilus latius.
Cyprinus, an exotic species, has proliferated extensively after its introduction in 1956. A decline in the population of indigenous species due to rapid changes in the environment was reported.
Deterioration of the lake
was recorded and confirmed by the test results in the lake. Ceratophyllum demersum recorded an increase in the lake area. Dense mono-specific stands have been created by the weeds. Further, a decrease in species diversity has occurred, an increase in the period of anoxic conditions, and accumulation of H2S in deeper waters have been reported. Pollution has also taken place due to a lack of wastewater treatment plants.World Wide Fund for Nature, which conducted an extensive survey of the lake in 1997, attributed the reasons for the deterioration of the lake, particularly on its banks, gradually turning it into a stinking marsh, to the following.
- Large-scale illegal encroachment on the periphery of Ganderbal and Qazibagh sides in the form of hundreds of trees, vegetable gardens, toilets, residential structures, garbage dumping sites
- Siltation due to noxious run-off from adjoining fields, stone quarries, and lime kilns;
- The flow of sewage and the use of fertilizers in the agricultural fields in its adjoining villages
- 80 per cent of the lake was seen under the thick blanket of weed
Lake restoration works
It was only in the year 2007 that lake restoration measures could be undertaken with the formation of the Wular-Manasbal Development Authority under the Government of Jammu and Kashmir.WMDA undertook the following measures for restoration and to improve the general environment of the lake.
- Removing the illegal constructions;
- Pedestrian walkway/pathway construction around the lake periphery of
- Manual de-weeding
- Dredging
- Demarcation of the lake
- Construction of STPs and
- Regulation of limestone extraction and afforestation of mountains to restore the lake's glory
A Shikara operator of the Lake area has reported that "there has been a lot of improvement in its condition".
