Lake Mansar is a famous tourist destination in the suburbs of Jammu which is receiving on an average 5 lac tourists every year. Subsequently a number of structures like 11 Government offices, JKTDC Cafeteria, Tea Stalls, Dhabas, Grocery shops, Bathing ghats, boating points, cremation ground, wildlife park, Dak Bungalows etc have been erected in its catchment area which have exerted their deleterious effects on the ecology of the lake. The various parameters estimated for the present study revealed that conductivity values were below 250 µmhos, TDS values were less than 500mg/l, SAR values less than 10meq/l, RSC values between 1.159 meq/l to 2.379 meq/l, SSP values between 21.110meq/l to 44.877meq/l and DPI varying between 38.006 to 81.507 which indicates that the water of Lake Mansar is best suited for irrigation purposes as it belongs to Class II category as per DPI chart.
