Interestingly, there is walkable terrain at the bottom of the pool. This could be a remnant of the fabled "Water Boots" or a ditched feature of the Iron Boots which are speculated to have allowed you to sink underwater like the Iron Boots from Ocarina of Time. Regardless of which, one reason why this ability could have been ditched is because the game takes place over an entire ocean. This could cause some major issues story-wise, like using the boots to sink to Hyrule early, and programming-wise, like where Link would appear when he sunk to Hyrule.
