Udayamarthandapuram is one of the important Birds Sanctuaries in Tamil Nadu. It is under the administrative jurisdiction of Thiruthuraipoondi taluk, Muthupet Block of Tiruvarur district. Created in 1998 in Tiruvarur District. It is near the confluence of Baminiyar-Kannanaar Rivers, covering 43.767 ha. The sanctuary is a seasonal wetland fed by small canals receiving water from Mettur Dam through the Koraiyar canal. As the Sanctuary is an inland wetland, it does not show the presence of structures like beach/shoreline/sand dune/ mud flats, etc. It has been declared as Protected Area in 1998. Fresh alluvium soil is deposited every year by irrigation water received from Mettur dam. The wetland plays the primary role of buffering by acting as a sponge during events of floods and extreme rainfall, & is a major source of ground water recharge. There is significant runoff from surrounding catchment area and the wetland acts as a sink for sediments. Udhayamarthandapuram Bird Sanctuary has a diverse habitat including large and deep reservoirs with a number of inlets and surrounding irrigated agricultural fields.
