Description ABSTRACT
Studies on Environmental Impact Studies on the status of Pong Dam Wetland in district Kangra of
Himachal Pradesh were conducted during the year 2011-12 in the vicinity of Pong reservoir with the objectives
to study the spatial distribution of bio-physical resources in the catchment of Pong wetland and to study the
effect of resource use on the spatial patterns of soil and water quality of wetland. The site selected for the
present study was Pong catchment area upto 20Km distance of tributaries in district Kangra of Himachal
Pradesh. Four tributaries viz. Buhal, Dehar, Gaj and Baner were selected in the reservoir vicinity. Each tributary
and its catchment was divided into four locations/distances of 5Km each. Location which does not form the
catchment of Pong was avoided. Under each location of tributaries catchment, three land uses were selected viz.
agriculture, pasture and the forest for study. Various physico-chemical parameters were analyzed in catchment
soils and water of different tributaries. The results of study revealed that the area under current study was
931Km2. Physico-chemical analysis of catchment soils showed that Electrical Conductivity, Phosphorus and soil
erodibility i.e. RDI value was found maximum under Agricultural land use with their mean values of 0.098
dS/m, 14.25 Kg/ha and 0.68×10-2, respectively ; Nitrogen and Potassium content was found maximum under
pasture/grassland land use with their mean values of 233.5 Kg/ha and 344.04 Kg/ha, respectively ; and
pH, organic carbon, calcium and magnesium content was found maximum under forest land use with their
mean values of 6.63 , 0.6% , 1914 Kg/ha and 310.3 mg/Kg, respectively. Heavy metal like Fe, Cu, Zn, Cd
concentration in the lake silt was within permissible limits. Physico-chemical attributes of water viz. colour,
pH, temperature, transparency, EC, total dissolved solids, total suspended solids, total solids, alkalinity, acidity,
BOD, COD, potassium, calcium, magnesium, total hardness, iron, sodium, chlorides and sulfates except DO
and phosphates at different locations of tributaries were found within the limits prescribed for irrigation and
drinking, no excessive concentration of any parameters was recorded during study period. The results of
Bathymetric analysis revealed that lake was sedimented upto the level of 6 meters since 1975.
