(2007-11) prepared by Wetlands International, South Asia, collation of existing
information augmented through rapid surveys, intensive community
consultations and participatory resource appraisals indicated the following:-
 The area of lake as per topo sheets of 1911 was 217.8 sq km which
includes 58 sq km of associated marshes. The area was reduced from157.74
sq. km to 86.71 sq km during 1911 to 2007.
 Overall there was reduction the lake area by 45% mainly due to conversion for
agriculture (28%) and plantation (17%). Further associated marshes were
reduced by 70% again due to conversions for
agriculture and settlements.
 One fifth of the water holding capacity has been lost over last three decades
due to siltation from degraded catchments and wetland conversions for
agriculture and willow plantations.
