The present study was carried out in Kosi and Sharda Rivers of Kumaun, of Uttarakhand. The various water quality parameters such as nitrate, phosphate, total hardness, TDS and alkalinity were analyzed from the period of November 2015 to April 2016. The nitrate and Phosphate increased in the spring months due to the higher phytoplanktonic production. Total hardness and alkalinity were higher during winter. Studied were indicated that both river water were suitable for aquatic organism, such as fishes. Water parameters levels indicated the moderate quality of water. Thus present study concludes that river water was not polluted; all the results are within permissible limit when compared with safe water quality standards.
