A SLEW of young celebs enjoyed the pool at Hollywood's Roosevelt Hotel over the weekend - oblivious to the fact that the hotel staff never drained the water after a dead body was found in the pool a week earlier, sources said.

At 4:30 a.m. Monday Oct. 13, Jordan Nagler, 30, a Rockville Centre, LI, native who was the executive director of International Student Exchange in Babylon, was found dead in the hotel's Tropicana Bar pool.

Ed Winter, assistant chief of investigations for the Los Angeles County coroner's office, told The Post's David Finnigan: "He was found at the bottom of the pool wearing swimming trunks. The staff at the hotel found him, but we don't know who actually removed him from the pool."

A Page Six source told us that days after Nagler's body was found, "The hotel management had a meeting, where they told staffers the pool didn't need to be drained" because "there was enough chlorine in it to kill the bacteria."

The tipster added, "Following the tragedy, the hotel held a meeting with employees of the Roosevelt, Teddy's [the club inside the hotel] and Tropicana Bar." Staffers were instructed not to "say anything to anyone" because, "We don't want this to get out."

One week later, the likes of Lindsay Lohan, girlfriend Samantha Ronson, Eve, Entourage's Kevin Connolly and frequent companion Stacy Keibler "were swimming in the unchanged water," our source added. On Monday, Justin Long, Sarah Chalke, Seth Rogen and Elizabeth Banks were there for an Effen Vodka-hosted party.

Stephen Brandman, chief operating officer of Thompson Hotels, which owns the Roosevelt, called reports about not draining the pool and shushing the staff "urban legend." He told us, "Somebody did die, but we don't think anything awkward or bizarre occurred. He had a heart attack."

Winter said the cause of death was undetermined. An LA cop told Finnigan there's no homicide investigation and the death "could be a result of alcohol consumption."
