The primary productivity of the river Mahanadi at Sambalpur has been estimated from January to December 1980 at three different stations. It varies from 1.03 g C m-2 day to 1.78 g Cm-2 day-1 with mean annual production of 518 g Cm-2. This is comparable production for riverine ecosystems in the tropics. However, the rate of primary productivity is adversely affected by human and animal abuse of the water, industrial effluents and sewage.
