The Water bomb threat in the Tsangpo-Siang reduces substantially as the Central Water Commission informed that Siang water rose steeply at midnight but started falling by morning at Tuting near the Indo China Border.
This is only shows that water traveled faster than what was calculated earlier and had entered India around midnight and is now hurtling towards Passighat. India earlier estimated the water level to reach by noon today.
According its latest tweet of thr CWC – Water Level on river Siang at Tuting (Monitoring stn.) in Upper Siang dist. of Arunachal Pradesh at 0600 hrs is 413.05 m with falling trend which is 7.38m below its Highest Flood Level of 420.43m.
Earlier India estimated that water bomb will enter India at 1400 hours today at Imkiyong at the Indo –China border. But CWC Hydrograph says it entered last night itself as it recorded steep rise in midnight and steep fall by morning.
A similar trend is now shown at Passighat where water level is fast going up and about to cross the danger level.
Despite border tension, India and China had agreed to share water related information and thus by the China had been constantly informing India about the landslide triggered barrier dam. This has given India head start to prepare for possible devastation.
Already Union minister of External Affairs Sushma Swaraj had spoken to Chief Minister of Assam Sarbananda Sonowal and Arunachal Pradesh Chief Minister Prema Khandu. The Cabinet Secretary last night held review meeting and the CWC was monitoring the situation from Delhi, Guwahati and Dibrugarh besides their ground stations of Arunachal Pradesh.
The CWC authorities comparing at the 2004 devastation of similar nature feels that this time damage should be less as 18000 CUSEC or cubic feet per second of water is supposed to flow through Siang which is much less than 2004 devastation when 1,00,000 CUSEC water flowed through the river causing 40 ft wave but did not have any impact 210 km down at Passighat. With that example, the CWC official was keeping an eye on the river asking the riverine people, not to venture in the river.
