  "content": "Residents along the Dikhow River in Assam's Sivasagar district received welcome reassurance on Thursday after official assessments confirmed that river flow remains completely unobstructed. Earlier concerns had emerged regarding a potential blockage upstream following a reported landslide in Nagaland's Longleng area, prompting immediate coordination between interstate administrative teams.\n\nGround Verification Clears Obstruction Concerns\nThe District Disaster Management Authority (DDMA) in Sivasagar initiated a comprehensive review after receiving inputs from authorities in Nagaland's Mokokchung and Longleng districts. Following ground-level inspections, officials confirmed that the natural movement of the river has not suffered any stoppage or barrier formation at the affected point. Observations recorded downstream on October 1 showed that water was moving freely and at regular velocity.\n\nGeographically, the reported landslide zone lies between sections of Mokokchung and Longleng districts in Nagaland. This location is situated approximately 44 kilometres upstream from the overhanging bridge at Naginimora, just before the Dikhow courses downward into Assam. Because this stretch serves as a vital hydrological conduit into the plains, authorities closely tracked channel conditions across the hill terrain.\n\nContext Behind Wednesday Downstream Alert\nThe official clarification effectively supersedes a precautionary warning issued on Wednesday by the Sivasagar district administration. At that time, riverside populations in downstream belts were placed on alert after unverified accounts suggested that a severe rockfall had cut off a major share of the river channel upstream.\n\nThat initial notification was circulated after a voice dispatch from the Longleng Deputy Commissioner indicated that debris had potentially choked nearly 80 per cent of the riverbed, leaving an estimated 20 per cent volume to trickle through. That assessment had been forwarded on the basis of a report submitted by the Chairman of Yongshei village in Longleng district. However, administrative leaders had noted that an exhaustive ground survey would take place the following morning to establish the ground reality. Thursday's findings conclusively proved that the primary river course remains clear and functional.\n\nWater Level Measurements at Bihubar and Weather Outlook\nHydrological tracking along the Dikhow River at the Bihubar monitoring station was conducted across September 30 and October 1 to check for any sudden surge or withdrawal. The designated warning threshold at this station stands at 102.77 metres, with the critical danger stage marked at 103.77 metres.\n\nField measurements verified that the river peaked at 94.73 metres, leaving it safely 9.04 metres below the designated danger line. According to the DDMA, the overall water trend has reflected steady or slightly increasing volumes within safe operational limits. Joint advisories from the India Meteorological Department (IMD) and the Central Water Commission (CWC) noted light precipitation in isolated pockets, alongside a rainfall forecast covering Mokokchung and Longleng districts over the subsequent two days.\n\nControl Room Contacts and Continuous Surveillance\nDisaster management teams have underscored that multi-agency monitoring remains active, with regular updates being gathered on river volume trends. Riverside communities have been urged to stay calm and promptly alert authorities if any sudden variance in current velocity or water characteristics is observed. Reports can be directed to the District Emergency Operation Centre (DEOC) through its mobile contact at 84718-64355 or the toll-free line at 03772-1077.\n\nWhat this means for you\nThis administrative clearance removes the immediate fear of flash flooding for downstream populations along the river basin.\n\n• Across India: Inter-state disaster management coordination between northeastern hill states and downstream plains continues to prevent false panic during post-monsoon weather events. Transparent verifications help maintain public stability and emergency readiness without unwarranted distress.\n• In Assam and Nagaland: Residents in downstream Sivasagar do not need to evacuate or pause routine river-adjacent activities. Community members noticing any sudden water level changes can directly notify the emergency operation centre at 84718-64355 or 03772-1077.\n• Weather and Rain Forecast: Rainfall warnings remain in place for Mokokchung and Longleng over the next two days. Travellers and residents in hilly border zones should remain observant of fresh debris along vulnerable road stretches.\n• Farming and Daily Routines: Agricultural operations and river transport can continue unhindered as water levels at Bihubar sit comfortably 9.04 metres below danger stage. No administrative restrictions or movement limits have been placed on downstream areas.\n\nWhy this happened\nThe situation developed after early unverified inputs suggested a catastrophic river blockage in Nagaland's high-altitude catchment area. The administration initiated joint checks to ascertain if landslide debris posed a flash flood risk to plains downstream.\n\n• Initial Source of Information: The alarm originated from a report by the Chairman of Yongshei village in Longleng district, which prompted a voice message from the Longleng Deputy Commissioner. That dispatch noted that roughly 80 per cent of the river channel was obstructed with only 20 per cent water escaping.\n• Terrain and Geographic Distance: The location lies between Mokokchung and Longleng, approximately 44 kilometres upstream from the Naginimora bridge. Rugged terrain necessitated an overnight delay before ground teams could physically inspect the waterway at daybreak.\n• Outcome of Ground Verification: Field assessments conducted Thursday confirmed that no obstruction or natural dam had formed across the riverbed. Water readings from October 1 verified consistent flow, proving the initial damage estimate incorrect.\n• Weather Influences: Isolated light showers occurred in the catchment zone without creating significant run-off spikes. Monitoring continues as meteorology authorities flagged light rain across Mokokchung and Longleng over the subsequent 48 hours.\n\nQuestions & Answers\n\n1. Is the Dikhow River blocked due to the landslide in Nagaland?\nNo, ground verification by authorities confirmed that there is no obstruction and river water is flowing normally.\n\n2. Why was a warning issued to downstream residents earlier?\nThe warning was sent as a precaution after an unverified voice message based on a village report suggested an 80 per cent river blockage.\n\n3. Where is the landslide site located relative to Assam?\nThe site lies between Mokokchung and Longleng districts in Nagaland, approximately 44 kilometres upstream from the Naginimora bridge.\n\n4. What was the recorded water level of the Dikhow River at Bihubar?\nThe river peaked at 94.73 metres at Bihubar, which is 9.04 metres below the danger level of 103.77 metres.\n\n5. Which emergency helpline numbers can residents use to report changes?\nResidents can reach the District Emergency Operation Centre at 84718-64355 or toll-free at 03772-1077.",
