2023 Sikkim flash floods
On 4 October 2023, there were heavy rains in Sikkim, India. Due to this rain, a lake on the Lhonak glacier overflowed, which created a big flood. This flood that started at around 1:30 am in the night rushed towards the Teesta III Dam in Chungthang which was the biggest hydropower project in Sikkim and broke it in the middle of the night, before the dam's gates could be opened. As a result, the water in the Teesta River downstream rose a lot, as much as twenty feet in some places. This caused a lot of damage in the area and areas in the surrounding particularly in West Bengal were also affected.
