"We have evacuated more than 34,000 people, some 49,000 to 50, 000 people are still stranded there. Efforts are being made to rescue stranded people in Uttarakhand," the Home Minister told the media in state capital Dehradun, after a meeting with disaster management officials.
He said that the death toll could rise further.
Floods and landslides, triggered by heavy rainfall, hit northern India Sunday, with Uttarakhand being the worst affected.
Forty bodies of flood victims were recovered from Haridwar, a Hindu holy city dedicated to the Hindu god Shiva, taking the toll in the rain fury to 190, said officials.
Meanwhile, rescue operation for some 10,000 Hindu pilgrims stranded in the holy sites of Kedarnath and Badrinath was picking up pace with the army sending over 40 helicopters.
Uttarakhand principal secretary Rakesh Sharma said casualty figures can be "shocking" as most flood affected ares remain out of access by authorities.
In Haridwar, 40 bodies of those killed in the flashfloods and incessant rain have been found in the mud and debris, the Press Trust of India quoted officials as saying.
Indian Prime Minister Manmohan Singh and Congress Chairperson Sonia Gandhi have viewed the devastated areas from air and promised massive central government aid to the local government.
The people stranded in the remote areas are running out of water and food as all the roads leading to these places were damaged by landslide and flood, said officials.
Indian officials described the devastation of the Uttarakhand as "unprecedented in 1,000 years" and said it would need at least five years for the flood-affected areas to recover.
Monsoon arrived two weeks ahead of normal time this year and took authorities by surprise.
In the Indian capital, the weather has returned to the heat with temperature re-bouncing back to above 45 degrees Celsius.
At least 40 bodies have been recovered from the river Ganges in the temple town of Haridwar, taking the toll in the flood-hit Indian state of Uttarakhand to 207, officials said.
The bodies were recovered on Friday, senior Haridwar police official Rajiv Swaroop told the BBC.
Haridwar is downstream from the region where heavy rains on Sunday night triggered flash floods and landslides.
Meanwhile, rescuers continue to search for survivors trapped in remote areas.
Officials said more than 33,000 pilgrims had been rescued in the last few days, but more than 50,000 people were still stranded.

State Chief Minister Vijay Bahuguna has described the floods as a "Himalayan tsunami".
Officials say that the number of dead could exceed 1,000 people, although the exact number will be known only after a survey of the entire region is completed.
Flood-related deaths have also been reported in Himachal Pradesh and Uttar Pradesh states and neighbouring Nepal.
The monsoon season generally lasts from June to September, bringing rain which is critical to the farming output, but this year the rain in the north of India and parts of Nepal has been heavier than usual.
On Friday, officials said 43 helicopters were being used to drop food and medicine and evacuate people trapped in towns and villages in the northern Himalayas.
The Indian army said they were making temporary bridges and working to restore road links.

Rescuers were trying to evacuate the last of the stranded from the holy town of Kedarnath, in Rudraprayag district, which has been among the worst affected areas.
State Agriculture Minister Harak Singh Rawat, who had visited the Kedarnath area, described the floods as the "worst tragedy of the millennium".
"It will take us at least five years to recover from the extensive damages caused to the entire infrastructure network in the Kedarnath area which is the worst affected," the Press Trust of India quoted him as saying.
Mr Rawat said he was "shocked" to see the extent of the damage caused to the buildings and area adjoining the shrine.
"The centre of faith has turned into a burial ground. Bodies are scattered in the area. Only the sanctum sanctorum is intact," he added.
Officials say the rains in Uttarakhand have been the heaviest in 60 years and the floods have flattened hotels and homes and washed away roads and dozens of bridges.
Prime Minister Manmohan Singh has described the situation there as "distressing" and announced a 10bn rupee ($170m; £127m) aid package for the state.
NEW DELHI, June 22 (Xinhua) -- As many as 600 people have been killed and hundreds still missing in monsoon floods which swept through the northern Indian state of Uttarakhand last Sunday, triggering landslides and washing away several towns and roads, a government official said Saturday.
The death toll is expected to rise once more dead bodies are recovered from the slush and mud lying everywhere across the hilly state, he said, adding that disaster management teams, comprising Indian Army, Indian Air Force and para-military troopers, have been trying their best to rescue people, mostly Hindu pilgrims, who are still stranded in the difficult terrain of the hilly state.
Indian Home Minister Sushil Kumar Shinde, who visited the flood- hit areas of the state this morning, said that some 73,000 people have been taken to safety so far and an additional 30,000 to 32, 000 still stranded. "We are hopeful of evacuating all people in the next two days," he told the media.
Some 17 foreign tourists are among those who have been air- lifted to safety this morning, the official said, adding that the next two days will be crucial for rescue work as the weather office has predicted that heavy rains may again lash the flood-hit state.
"The rescuers, led by the Indian Army, are racing against time to rescue as many people as possible, still stranded in the hilly terrain. Many people have already died due to hunger and illness. Indian Army road engineers have been pressed into service to build bridges swept away in the floods," he added.
Local TV channels showed footage of Indian Army and Indian Air Force choppers air lifting people, including aged pilgrims, who are stranded in upper reaches of the state, including the pilgrimage sites of Badrinath, Kedarnath, Gangotri and Yamunotri, without adequate supply of food and water.
Flood survivors were evacuated to state capital Dehradun which has also been made the base for the relief effort, from where rescue workers, medicines and food are being flown to the flood- hit areas. Many of the survivors have been recounting the horror stories to TV channels, with some saying that they saw rocks and boulders, as big as cars, hitting those killed in the flash floods in the hilly terrain.
Indian Prime Minister Manmohan Singh has announced a 10 billion rupees (170 million U.S. dollars) relief package for the state.
The monsoon arrives in India in June end and stays till September. But, this year, the weather office says that the showers came a fortnight ahead of schedule. Moreover, the rains in Uttarakhand is said to be the heaviest in 60 years.
The death toll from monsoon flooding and landslides in mountainous northern India rose to nearly 600 on Friday with rescuers finding bodies in the Ganges and in the muddy, broken earth, officials said.
The air force dropped paratroopers, food and medicine for people trapped in up to 100 towns and villages cut off since Sunday in the Himalayan state of Uttarakhand where thousands of people are stranded, many of them Hindu pilgrims who were visiting four shrines in the area.
The Uttarakhand state chief minister, Vijay Bahuguna, told CNN-IBN television channel on Friday that 556 bodies had been seen buried deep in mud and the army was trying to recover them. Rescuers also found 40 bodies floating in the Ganges near the pilgrimage site of Haridwar, said Rajiv Swaroop, a police officer.
Rakesh Sharma, another state official, said on Thursday that the death toll might reach the thousands, but the exact figure would not be known until the entire region had been checked.
Sushilkumar Shinde, the federal home minister, told reporters in Delhi that 34,000 people had been evacuated so far and 50,000 more were stranded in the region. Roads and bridges were washed away by the floods or blocked by debris.
A spokesman for Uttarakhand, Amit Chandola, said the rescue operation was centred on evacuating nearly 27,000 people trapped in the worst-hit Kedarnath temple area, one of the holiest Hindu sites dedicated to the god Shiva, located high in the Garhwal Himalayan range. The temple escaped major damage, but debris covered the area around it and television images showed the bodies of pilgrims strewn around the area.
Soldiers and other workers reopened dozens of roads by building makeshift bridges, accelerating the evacuation, Chandola said. More than 2,000 vehicles carrying stranded Hindu pilgrims had moved out of the area since late on Thursday and thousands of soldiers were continuing efforts to reach the worst-hit towns and villages, he said.
Thirty-six air force helicopters have been ferrying rescue workers, doctors, equipment, food and medicine to Kedarnath, the town closest to many of those stranded, said Priya Joshi, an air force spokeswoman. Seven aircraft carried paratroopers and fuel to the region.
Hundreds of people looking for relatives demonstrated in Dehradun, the Uttarakhand state capital, where flood survivors were taken by helicopter. They complained the government was taking too long to evacuate the survivors, with helicopters bringing in four to five people at a time.
Jasveer Kaur, a 50-year-old housewife, said she and her family survived by taking shelter in a Sikh shrine, which withstood the flood, located in Govind Dham.
"There was destruction all around," said Kaur after she was evacuated by an air force helicopter. "It was a nightmare."
Google has launched an application, Person Finder, to help trace missing people in Uttarakhand. The version is available in both Hindi and English versions.
The annual monsoon rains sustain India's agriculture but also cause flooding that claims hune numbers of lives and damages property. The neighbouring Uttar Pradesh state said 17 flood-related deaths had occurred there since the heavy rains on Sunday.
