The Ocean Hole is a natural "blue hole" that the locals say is bottomless. It is actually an inland salt water lake, a mile from the oceans, yet it is filled with salt water sea life, and rises and ebbs with the tides.
Therefore, it definitely has a connection with he ocean, although no-one has found the connection (Jacques Cousteau, formerly a part-time resident of Windemere, tried unsuccessfully.)
The hole is full of fish, but no fishing allowed, although you are welcome to swim and feed the fish.
