stuck in Skyview Temple?

I'm in the Skyview Temple, in the first three connected rooms -- the middle room is the one that contains the map, the rooms to the left and right contain some skulltulas and pink switches.

Unfortunately I raised the water level (twice) before I realized there was another pink switch in a hole or tunnel at floor level in the room to the right...

I don't have the Water Scale (or whatever it's called) yet, so I don't seem to be able to dive. But there also doesn't seem to be any way to lower the water back down (hitting any of the switches again has no effect).

So it would seem I don't have any choice but to start the game over from scratch. Has anyone else encountered this?

Solution 1:

According to several walkthroughs -- which I had consulted in desperation -- you have to crawl into that hole/tunnel because one of the pink switches is there.

I am 99.9% sure I never did that. I don't believe I even noticed the hole until after consulting the walkthroughs -- shame on me -- but at that point I had already raised the water level.

But as it turns out, I was able to move on. The water was high enough that I could jump to the vines on the right wall in the middle room and climb up. I thought I had tried this after raising the water level a 2nd time, but it's possible I didn't. (Or maybe I did but missed the vines because I was not pointed in quite the right direction.)

But I'm almost positive that I never crawled into that hole ... which would mean the walkthroughs are inaccurate on that point.
