ABSTRACT

 

Chakkamkandam lake of Kerala (India) is a water body situated near a township famous for pilgrimage tourism. A couple of decades back this water body was the main source of income for the native population by means of both capture and culture fisheries which was altered to a present condition of adversity for the sustenance of the aquatic lives. To assess the pollution status of the water body field visits were done at regular intervals and water samples were collected monthly for one year during 2009 to 2010.Water quality was estimated as pH, dissolved oxygen, turbidity, and ammonia. The CCME Water Quality Index was calculated. It was inferred that Chakkamkandam lake has a CCME WQI value which can be categorized under the Poor status. Fish diseases were reported by native fishermen during this period, which was in accordance with the study inferences. The water body is under pollution risk and mitigation measures need to be adopted.
