abstract={The present study deals with the study of Physico-chemical characteristics and the periphytic algal community of the Ragda Gad stream in district Pauri Garhwal, state Uttarakhand, India. The coordinates of this spring-fed stream are 30¡ã<SUP> </SUP>11¡¯15¡± N and 78¡ã46¡¯22¡± E. During the investigation it was found that the periphytic algal community of Ragda Gad stream mainly comprised 25 taxa belonging to 3 major class namely Bacillariophyceae (<i>Cymbella</i><i> sp.</i>,<i> Synedra</i><i> sp.</i>,<i> Fragilaria</i><i> sp.</i>,<i> </i><i>Gomphonema</i><i> sp.</i>,<i> Navicula</i><i> sp.</i>,<i> Tabellaria</i><i> sp.</i>,<i> Achnanthes</i><i> sp.</i>,<i> </i><i>Bacillaria</i><i> sp.</i>,<i> Diatoma</i><i> sp.</i>,<i> Amphora sp</i><i>.</i><i>,</i> and<i> Nitzchia</i> <i>sp.</i>, etc), Chlorophyceae (<i>Cladophora</i><i> sp.</i>,<i> Oedogonium</i><i> sp.</i>,<i> Spirogyra sp., Microspora sp., Volvox sp., Zygenema, Ulothrix sp., Closterium sp., Cosmarium sp. and Geminela sp,)</i> and Cyanophyceae (<i>Nostoc sp., Anabaena sp., Rivularia sp. and Phormidium sp.</i>). The dominance of Chlorophyceae in the stream indicates the healthy condition of the stream ecosystem. It is having crystal clear water and is free from pollution. Further, as a result of less anthropogenic pressure, the quality of water is rather superior.},
