The quarry we dive in is an old lead qaurry where they hit a natural spring so it flooded... 200' or so to the bottom, some 'caves' at the bottom with train tracks and far back in one of them is a train that they didnt get out when the place flooded. Despite being a lead qaurry, they claim the waters safe.
Anyways, point being, alot of flooded qaurry's are becuase they hit natural springs.
