Pulicat Lake is one of the major important lakes in southern India is taken for the present study to monitor the health status of the lake by determining the Organic matter (OM) and carbon content (CC). A total of 9 sediment samples were collected from pulicat lake at random locations and co-ordinates of the sampling stations were recorded by using a hand held GPS. Ranges of sand, silt and clay are 11.8% to 93% (av. 61.1), 6.7% to 87.8 % (av. 31) and 0.3% to 47.8% (av. 12.2) respectively. More than 60% of the sand grains in this environment are mainly medium to fine grade and predominance of silty sand. The organic matter values ranges from 1.89 to 8.62% and controlled by grain size patterns. Silt clay and clay in the central part of the lagoon are having high carbonate content (range 0.5 to 3.2%). Like organic matter, the carbonate content is less in the coarse sediments and in fine sediments of the central parts of the lagoon is more. The average carbonate content of the Pulicat Lake sediments is 1.45%. The sediments were mostly transported by bottom suspension and rolling, graded suspension and uniform suspension mode.
