Since bodies are still being found from the slush and debris left behind by the river in both the states, the exact casualty count will be clear in the next few days after collating the details, officials said.
The release of water from the Chungthang dam led to a sudden increase in water levels up to 15-20 feet high downstream, defence spokesperson Lt Col Mahendra Rawat said.
On day three after a flash flood wreaked havoc in Sikkim's Teesta basin, the number of bodies recovered from the river and mud embankments downstream rose to 22, including seven army men.
Landslides triggered by heavy rain cut off large parts of northern and eastern Sikkim, including Nathula pass, while efforts were being made to restore connectivity, officials said on Friday.
The NRSC satellite imagery revealed that the lake covered approximately 162.7 hectares. Its area increased to 167.4 hectares on September 28 but drastically reduced to 60.3 hectares.

The Sikkim Government has confirmed that 14 people have died so far in the flash floods that occurred in Sikkim in the early hours of Wednesday.
A study by an international team of researchers had warned two year ago that the South Lhonak lake in Sikkim may burst in the future and significantly impact the downstream region.

With rescue teams finding it difficult to reach far-flung quake-hit areas in Sikkim, hundreds of survivors are trekking out of their villages, crawling sometimes to negotiate dangerous stretches. Hundreds of villagers from inaccessible higher areas of Lachung, Lachen and Chungthan have gathered in Tung after an arduous trek down and are being taken to safe places. Army sources said hundreds of villagers reached Tung, 10 km from Chungthang, one of the worst-hit areas.
Prime Minister Manmohan Singh on Thursday made an aerial survey of quake-ravaged areas of Sikkim and announced Rs 1,000 crore as Central assistance to the state.
