PHYSICO- CHEMICAL FEATURES OF VELI LAKE (SOUTHWEST COAST OF INDIA)
The Veli Lake is the smallest among the backwaters of Kerala. It is situated 8 km north west of Trivandrum City at 8o 28’ N latitude and 76o 57’ E longitude. The system widens from the bar mouth to the eastern part and is 2 km long and 0.3 km broad. It is shallow with a mean depth of 2-3m. The partially treated sewage and the completely untreated industrial effluents are the main sources that brought undesirable changes in the lake. For the present study three stations were fixed in the lake to test the physicochemical features (April 2000-March 2001).The results shown that monsoon and less polluted zones with minimum undesirable physico-chemical parameters.
