The water quality issue in Kashmir has not yet got its due importance. A comprehensive water quality monitoring program is indispensable to assess the water quality status of the national rivers. This paper assesses the monitoring data on water quality of the longest river of Kashmir Valley i.e., River Jehlum from 2003 to 2012 and strives to convert it into an understandable format that can be easily interpreted using various analytical techniques pertaining to Water Quality indexing(WQI) such as Canadian Water Quality Index(CWQI) and Arithmetic Water Quality Index(AWQI) where the former is computed using CWQI 1.0 model while the latter is calculated using Weighted Arithmetic Index method. It also formulates certain surface water quality standards according to different water usages and detects long-range trends in selected water quality parameters which account for various potential problems causing alterations to the quality of River Jehlum. This study also identifies most polluted reaches and proposes management scenarios for the reduction of the build-up pollution in River Jehlum.
