JORHAT: Due to incessant rain, almost all the tributaries of the Brahmaputra are flowing above the danger level since Sunday evening, said Central Water Commission (CWC) sources. According to CWC sources, the water level of most of the Brahmaputra tributaries was flowing above the danger mark due to incessant rain in the higher altitudes of Nagaland, Arunachal Pradesh, Karbi Anglong and Dima Hasao. The Brahmaputra is expected to flow above the danger mark for the next 24 hours. Alert has been sounded in sensitive zones like the Kaziranga National Park and Pobitora Wildlife Sanctuary as water from the Brahmaputra along with its tributaries Difloo and Jia Bharali might submerge the park areas. Kaziranga National Park has already sounded alert for vehicles to keep the speed limit up to 40km/hour within the park area on NH-37 or to pay fine up to Rs 5,000 for over speeding.
