Abstract

It is generally observed that a variety of physical and chemical variables
have considerable impact on the biological life in a mountain river which
include plankton, benthic algae, benthic invertebrate and finally the fishery
resources. They are often subjected to extreme hydrological disturbances
particularly during rainy seasons when increased volume of water create
'Wash Off" situation for existing fauna and flora. A case study of a lesser
Himalayan river - the Gaula which drains the south-central part of Kumaon
region in Uttaranchal is presented here. Since this river does not get snowmelt
water, it mainly depends on steady flow of the groundwater round the
year. The climate of the area is characterized with long winters, short summer
and good amount of rain during monsoon months. The infiltrated groundwater
which seeps into the surface soil layers during monsoon seasons is the chief
source of discharge of water during winter and summer season.
