It happened just after 10:30 a.m. at the Steve Benko Pool at Waveny Park.
The Tesla plowed through a fence and set of trees before plunging into the water. Police say he was trying to park at the time.
The community pool was closed when it happened, so no one was swimming or in the path of the vehicle.
Lifeguards and first responders entered the pool to help the driver out of the vehicle.
Lifeguard Mike D'Urso, 18, described what happened.
"Me and my coworker were setting up the umbrellas when we heard a loud crash and we turned around and there was a car right in the middle of the pool," D'Urso said.
D'Urso said the man was conscious and alert but the vehicle began to take on water.
"The car began to sink a couple minutes in, and my concern was that the water would rise above his head and wouldn't be able to breathe," D'Urso said.
D'Urso and EMS workers pulled the victim out through the passenger side window. The driver said he wasn't injured, but he was taken to a local hospital for evaluation.
The pool will have to be drained, cleaned and refilled. Officials hope to have it reopened by the weekend.
