Brooklyn residents were still reeling Tuesday from heavy flooding that wreaked havoc during torrential downpours in the Big Apple a day earlier.

Amanda Denesha of Gowanus said she was forced to wade through waist-deep floodwaters donning sandals Monday evening as she made her way into her Carroll Street home where the rainwater was up to her ankles.

“It was dirt and water. It looked disgusting,” said Denesha. “It was going into the basement and going into my apartment.”

Denesha said she was “scared” for her dog and “just wanted to make sure he was OK and did not get electrocuted.”

She noted that the flooding “happened very quickly” and within 40 minutes the waters had receded.

“We threw away our throw rug. We bleached the floors,” Denesha said.

Online videos showed floodwaters completely inundating the intersection of Carroll Street and Fourth Avenue Monday night with parked cars submerged.

Eunice Lee’s gray 2008 Toyota Prius that was parked in front of her apartment on Fourth Avenue was one of the vehicle casualties.

“I couldn’t go inside [the car]. The water was really high. The seats are wet,” said Lee, who ran to move her car after the rain started but was too late.

“It happened in less than 10 minutes,” Lee said. “I was taking a shower. When I came out it was already flooded. We ran down, but if we had opened the door the water would have just flooded in even more.”

North Carolina resident Thomas Flaherty, who was in town visiting his daughter, also suffered a water-logged car.

Flaherty had parked his 2011 gray BMW on Carroll Street, and during Monday’s storm “the water lifted it up and put it up against the light pole.”

“It is probably totaled because of the water damage,” he said, adding, “I tried to bail it out…I tried to start it. It started up, but it started smoking.”

Liam O’Brien, a co-owner of a new Fourth Avenue pub called Gowanus Gardens, said the flooding has delayed the bar’s opening, setting the owners back about $20,000.

“Luckily we are covered by insurance. We have to look at the positive,” O’Brien said, adding that he called his partners and asked, “What the f–k is happening” when he saw the wild scenes of the flooding emerge on Twitter.

Floodwaters soaked the pub’s new wood floor.

“We are hoping the floor did not get too f–ked up because it’s not sealed yet and it’s wood,” O’Brien said. “Our basement is still a little flooded. There are puddles of water down there.”

Monday’s thunderstorm caused flooding in several areas across the city.
