The CNN video below shows the damage caused by Irene in the small town of Prattsville, New York. The Catskills town of just over 300 homes was almost entirely underwater when newscasters arrived.
A state police helicopter was needed to rescue over 20 people stranded in the town yesterday, according to CNN.
The town was flooded when a local creek rose over 15 feet in under 12 hours. Greene County Administrator Shaun Groden told CNN that the rainwater spilling off the Catskills sent a volume of water that was greater than Niagara Falls through Prattsville.
According to the Associated Press, continued flooding on bridges and roads has cutoff at least three towns in New York and “some Vermont rivers still haven't reached their peak.” Flooding in Vermont is the worst in a century.
In Bartonsville, Vermont, strong floodwaters carried away a 141-year-old covered bridge as onlookers watched in shock.
