 The present study was carried out to assess the water quality of Manawar Tawi river of Rajouri during 

May 2013 to April 2014 in four different seasons viz. Summer (March to June), Monsoon (July– August), 

Post Monsoon(September to October) and Winter (November to Feuary). Two stations were identified on the basis of 

anthropogenic load viz. Station I & Station II. Water samples were analyzed for physicochemical parameters including: 

Air temperature, Water temperature, Transparency, pH, DO, FCO2, BOD, Carbonates, Bicarbonates, Total dissolved 

solids(TDS),Total suspended solids(TSS),Conductivity, Calcium, Magnesium, Nitrates, Chloride, Sulphates and Phosphate 

from two different stations. The results revealed seasonal variations in the Physico–chemical parameters at Station I 

& Station II and further investigations showed that water was clear with high values of pH and DO and low values of 

FCO2, TDS, TSS and BOD at Station 1 while at Station II high values of BOD, nitrates, chlorides, free CO2, TDS but 

low value of DO & pH indicated pollution load. The comparative study showed that the water quality of the Manawar 

Tawi was degraded due to the presence of significant amount of pollutants discharged from Rajouri city at Station II so 

water is not potable at this site. To maintain the healthy ecosystem of the river there is a need for proper management 

and monitoring of water quality of the river
