Through anthropogenic activities such as dam building, river management works, indirectly through developments and disturbances in the landscape of the watersheds in particular effluent discharges and deforestation increasingly threatened the environmental integrity of freshwaters systems, world wide. In order to access the monthly and seasonally variations of “Ropar Weland”, study on various physio-chemical parameters was carried out from October 2015 to September 2017 at four representative sites (S1, S2, S3 and S4). The seasons were generally divided into winter (December to February), summer (March to May), monsoon (June to August) and autumn (September to November). Maximum amount of all the parameters except DO and free CO2 were observed in summer and monsoon season and minimum in winter season. Minimum value of DO and free CO2 during summer season is due to the higher temperature because temperature is inversely proportional to DO. Rest of the parameters such as phosphate, sulphate, magnesium, calcium were widely fluctuated according to seasons and are under permissible limits.
