Located in the western part of Odisha, the Hirakud Dam on the Mahanadi River, is about 20km north of Sambalpur town. The dam, along with its twin observation towers, Gandhi Minar and Jawhar Minar, are often visited as part of a day tour from town, especially between October and March. But hardly any one ventures along the right dyke of the bank that leads into a little known wildlife sanctuary. A halt at Zero Point offers a glimpse of the forest on one side and the reservoir on the other.
