The water level in the project's bottom portion has since dropped.

According to reports, eight diversion tunnels have been blocked in all. Local authorities have reported that lakhs of fish have died due to the sudden drop in the water level of the Subansiri River.

It should be mentioned that the diversion tunnels were closed when the main dam's construction was finished. However, the main diversion tunnel was reopened due to the significant landslip.
