WATER QUALITY ASSESSMENT OF MOHAND RAO RIVER OF DOON-VALLEYPrashant-Dwivedi Purandara Bekal I.P.PandeyAbstract Streams and rivers are the distinct ecosystems, supporting significant and unique biodiversity. Stream morphology, habitat diversity and water quality are a reflection of catchment characteristics such as topography, geology, soils and vegetation. Direct impacts include changes in flow regime and habitat type resulting from dams, weirs etc; loss of riparian vegetation, causing major effects on riparian and in-stream habitats and processes; increases in sediment transport from the catchment, leading to changes in water quality. Therefore, water quality monitoring is the basic need for the people who rely on river water for their day to usages. In this context, a stretch of 15 km from Dat-Mandir to Ganeshpur of the Mohand-Rao river(Doon valley) was studied during the year 2004 and 2005. The study revealed that, the river water is free from pollutants, however, the study stressed the need to keep the flow condition in a optimal satge.
