No way to know really. We know it came out high enough for a boat to be sucked into a still spinning propellor (Talk about Excedrin Headache #666!) but I doubt it would have come up much higher since by then, the bow was already in contact with the bottom.
>>could It be possible that the water was deep that day than It is now.<<
No. The depth of the water in this area is well known and was known back then. To get the sort of shift in depth you're thinking of would take a supermassive earthquake the likes of which hasn't been seen on this planet at any time in recorded history.
UN-recorded may be another matter entirely, but that goes way too far back to be of any relevance here.
She could have not come very high in the air. The ship was a little over 882 feet long and the water about 400 feet deep. Her stem was touching the seabed while her stern was still out on the water.
Also she was rolling to starboard, the stern settled back and sunk under water.
