PRODUCTIVITY OF CHAMBAL RIVER IN RELATION TO WATER QUALITY

Reddy P. B.*

ABSTRACT

The productivity of a fresh water pond depends on its water quality. The present research was carried out to study the limnological aspects of upstream and downstream of Chambal River at Nagda, in response to changing physicochemical factors of surface water. The results of water quality parameters reveal that, Juna Nagda (downstream) was highly polluted as it exceeded acceptable limits of water quality values studied. The values of gross primary productivity (GPP) in the upstream (Methwasa) was found to be 0.38 gC/m2 /day while it was 0.058 gC/m2 /day at Downstream (Juna Nagda). It clearly indicates that toxic municipal and industrial effluents considerably reduced phytoplankton primary productivity in the downstream. This study provides base line information to find out influence of water quality on primary productivity. Regular supervision of the water quality is recommended to prevent the pollution in this segment of the River.
