The Jagdispur Reservoirs was constructed in the early 1970s for irrigation purpose.The reservoirs is surrounded by cultivated land and a few smaller lakes which serve as a buffer zone for bird movement.Current uses of the reservoir and adjacent areas include fishing, grazing, fuel wood and fodder collection, domestic use of the Reservoir such as for laundry, and harvesting of wetland products. The area is also popular for picnics, swimming, boating, bathing, and other forms of recreation and supplies water for irrigation in 6,200 ha of surrounding cultivated land. The water body has great potential for commercial stocking and production of fish. Surrounding areas are primarily used for farming. The site has been proposed as a designated bird sanctuar.The site is visited by a large number of wintering and staging waterfowls and provides excellent foraging habitat for both resident and migratory bird species Bird species symbolic of the area are the Falcated duck, Mallard, Tufted duck.

13. Conclusions
• Vegetation is in a submerged succession stage with patches of floating species
and reed swamp formations
• Dense aquatic macrophyte vegetation indicates eutrophic status and a high
sedimentation rate
• Rapid succession towards a marsh meadow condition, reduction in the life span
of the reservoir in the absence of a desiltation tank
• Currently managed under the Reservoir Management Committee
