Western Ramganga is the major river system of kumaun Himalaya, was studied for seven prime physicochemical parameters and two biological factors at five locations for a period of three years (2009 2012) at monthly intervals. The physical factors are water temperature, water current and turbidity of water; whereas the chemical parameters of river comprise pH, dissolved oxygen, total alkalinity and total hardness of water. The biological factors considered were macro-zoo benthos and plankton of the river. River was highly productive as presence of various class and order of benthos, zooplankton and phytoplankton although there were no sign of problems like eutrophication. Biological studies indicate that river water was fit for aquatic organism, such as fishes because of there were plenty of food. Over the years of time, river has been subjected to study and observer very modest human interference (because of very little or no urbanization and since there were no major industries) and water quality was not to be getting deteriorated. physico-chemical parameters levels indicate the moderate quality of water. Thus present study concludes that river water was not polluted; all results are within permissible limit when compared with safe water quality standards
