Site description Udhuwa or Udhwa Lake is situated 11 kms southeast of Rajmahal in the Sahebganj district of Jharkhand state. This Bird Sanctuary is constituted by two waterbodies, namely Pataura (155 ha) and Berhale (410 ha). Pataura is a comparatively clean waterbody and the average depth is about 2 m whereas Berhale is a shallow one having average depth of about 70 cm. Berhale is largely choked with aquatic vegetation, with small pockets of clear water. Both these waterbodies are inter-connected by a water channel and the whole bird Sanctuary is connected with River Ganga at Farraka by Udhuwa Nala which is a 25 km stretch. Pataura is surrounded by hillocks on one side, and on the other side, the Forest Department has done some plantations (on the hillocks).
