A total of 13 species belonging to 6 families under 2 classes of Mollusca were encountered. The class Gastropoda dominated the faunal composition (91%) with 11 species under 5 families and the class Bivalvia constituting (9%) with 2 species under single family. Among them <em>Bellamya bengalensis, Lymnaea accuminata, Indoplnorbis exeutus, </em><em>Gyraulus convexiusculus</em><em>, Melanoides tuberculata </em>and <em>Lamellidens marginalis </em>were the most dominating taxa. The highest number of molluscan taxa was from the family Viviparidae (3 spp.) 29% followed by Planorbidae (2 spp.) 27%, Lymnaedae (3 spp.) 23%, Unionidae (2 spp.) 9%, Thiaridae (1 sp.) 8% and lowest from Piladae (2 spp.) 4%. Seasonal variation showed maximum density in the summer and minimum in the monsoon. Correlation (p&gt; 0.05) indicate that <em>B. bengalensis, L. accuminata</em>, <em>I. exustus, L. marginalis </em>had close dependency to soil pH, soil organic Carbon, Soil organic matter and sand particle whereas <em>M. tuberculata </em>and <em>G. convexiusculus </em>show significant positive correlation with silt and clay particle. Biodiversity indices indicating low species diversity and richness of molluscs in both migratory bird visiting and non-visiting lakes. These findings emphasized the importance of protection and management of molluscs fauna in the lakes for supporting the food for the migratory birds.</p><p>Bangladesh J.
