A 33-year-old Manhattan man jumped into the North Pool at the 9/11 Memorial & Museum on Monday afternoon and survived the leap with just a leg injury – but was awaiting criminal charges, according to police.

Cops responded to the World Trade Center site in lower Manhattan around 1:30 p.m. after a Port Authority employee spotted the man making the leap into one of the two tiered reflecting pools at the memorial.

A video posted on X, formerly known as Twitter, shows the man lying down in waters in the pool’s central basin, peering into the 20-foot-deep opening in the middle.

Police said he suffered an injury to his left leg and was taken to Bellevue Hospital, where he was in stable condition.

The man, whose name is being withheld by The Post pending criminal charges, was taken into custody.

It was not immediately known why the man jumped.

The pair of reflecting pools at the memorial site mark the former footprints of the two Twin Towers before they were felled during the Sept. 11, 2001, terror attacks and now honor those who died that day.

Both pools feature a 30-foot waterfall, with the water dropping into an acre-size basin that flows into a smaller opening in the center that drops another 20 feet.

The site is public and access to the grounds, including the reflecting pools, is not restricted.

According to law-enforcement sources, a potential jumper was talked down off the ledge at the South Pool last month.

Last year, another individual did leap into the North Pool, the sources said, although details of that incident were not immediately available.
