Up to 200,000 people were evacuated from their homes in north-eastern Pennsylvania alone because of rising waters on the Susquehanna River.
A state of emergency has been declared across large parts of New Jersey, New York and Pennsylvania states.
The flooding follows days of torrential rain along the east coast.
New York Governor George Pataki - who ordered the National Guard to help with evacuation efforts - said it was by far the worst flooding he had seen in his 12 years in the job.
The largest evacuation effort was taking place in Wilkes-Barre, in Pennsylvania, where rising waters were expected to crest a few feet from the top of the 41ft (12.3m) levees protecting the town from Susquehanna's rising waters.
Luzerne County Commissioner Todd Vonderheid said the evacuation of 200,000 residents was "honestly precautionary".
"We have great faith the levees are going to hold," he told the Associated Press.
Across the region, emergency helicopters, divers and boats were rescuing people left stranded by the floods.

"We tell people, 'Turn around, don't drown,' " Edward J McDonough, a spokesman for the Maryland Emergency Management Agency, told the New York Times.
"If you see rainwater on the road, don't cross it, because you don't know how deep it is or how fast it's moving."
