Abstract
The present communication highlights the hydrological regime of Beas river in Kullu valley which was studied at four sites during the whole year of 2003. Flow of current ranged between 378 - 432 cubic feet /sec. Depth of river ranged between 1–4 mts. Width of the river ranged between 40-50 mts. Water temperature ranged between 5.2 ºC -17.7 ºC. pH showed only little fluctuation. Transparency of the water was high throughout the year except rainy season. Dissolved oxygen was high and it showed an inverse relationship with water temperature. Total alkalinity was also high. Investigation of fish fauna of the river in the valley revealed the presence of 6 species of fishes belonging to 3 orders and 3 families.
