'The maximum level at the Tapovan barrage is 1803 meters, but, according to reports, the water level crossed 1808 meters, which led to breakage. By the time the water reached Joshimath, its level had touched 1388 meters, breaching all records. During the flash floods in the state in 2013, the highest water level at Joshimath was 1385.54 metres, experts said "
So, the height of the supposed wave was 85 meters (1388 - 1803 = 85).
The beginning of the natural disaster - February 7, 2021, 10: 00-10: 15 local time (hereinafter).
26 km (the approximate distance from the site of the starting of catastrophe to the location of the power plant in the Joshimatha region, the wave passed in 15-30 minutes (the destruction of the power plant - at about 10:30).
Consequently, the wave speed: from 50 to 100 km per hour.
There are also reflections, for example: "With temperatures in the hills of Utttarkhand's Chamoli district dropping to below zero in the month of February, why did the glacier break off now? According to Manish Mehta, senior scientist at Wadia Institute of Himalayan Geology, 'This is an anomaly. In winter, glaciers remain firmly frozen. Even walls of glacial lakes are tightly bound. A flood of this sort in this season is usually caused by an avalanche or landslide. Neither seems to be the case here.'

However, rampant construction continues due to which the disaster was inevitable. This was a manmade disaster.'"
Another material (TIMESOFINDIA) tells that the fish before the disaster (from about 09:00) behaved in a completely unusual way - apparently, they had foresaw a disaster ... (Did fish sense the oncoming deluge?
