Site description The Vaduvoor Lake Bird Sanctuary is situated in the Tiruvarur district of Tamil Nadu. It is c. 24 km from Thanjavur and 15 km from Mannargudi. The Lake has a depth of c. 2.5 m, and receives water mainly from the northeast monsoon and the Vennaru river. The Lake irrigates about 1,356 acres of agricultural land. Nayvasal and Vaduvoor villages are situated around the Sanctuary. The road to Mannargudi borders one side of the Lake. The other sides are protected by huge bunds. Migratory birds start to arrive by October and stay till February to March. This freshwater lake is rich in aquatic flora, with submerged, floating and emergent vegetation. Ipomoea carnea is seen in many parts of the Lake. There are thickets of Prosopis chilensis. The Forest Department has planted Acacia nilotica in the lake environs.
