"The Swirling Reef of Death got it's name after a dull history of just being named after a person. Teenagers were tasked with making up a new name for the reef so it would have a great name, therefore, the Swirling Reef of Death was born. "
So was this originally "Dave's Pond"?
I think unless someone with direct knowledge can be found - there is unlikely to be a definitive answer.
In regards to the name Swirling Reef of Death, I came across this quote from Dave who was the owner of Scuba Shack:
“It’s a local joke,” Dave explained in his laconic way, his face deeply tanned from decades of ocean work. “The reef has had two or three different names. Not long ago we had a couple of thirteen year old boys on board and they came up with the new one and so far, it seems to be sticking.” (somewhat goes along with "The Perfect Dive" site quote)
Think if Dave's name had been attached to the name of the site before, he may have indicated so.

A Misty Christmas
Changes in Latitude beach bar was a very short walk from the old Scuba Shack which was also used as a marker for Dave's Pool. It became Coconuts beach bar, which was our favorite, but it was recently closed or sold and most likely has a new name (if sold.)
The picture from the website
Scuba Shore Diving Site Page for: Dave's Pool of USVI, St. Croix, Caribbean that the OP came across shows the site, Dave's Pool, and which has the old pier in the background, far left. That would definitely put the site just north of the pier.
As memories are coming back to me, it was never mentioned to us that we could shore dive from this location when it was Scuba Shack nor when it became N2theBlue. We just hopped into a vehicle and they took us to the pier to get on the boat.
