It receives water mainly from the Vellar river, which orginates in Salem district and flows from west to east. The tank also receives water from Tholudur regulator through a supply channel, and drainage from catchment areas during the northeast monsoons. The Reservoir has a catchment area of 129 sq. km. This reservoir supports 10,000 ha of agricultural fields for irrigation. The length of the bund is about 4 km. The maximum depth of the lake is about 9 m. The waterbody has rich benthic flora and other hydrophytes. The Forest Department has planted Acacia nilotica especially in the northern part of the Reservoir.
