I've already gotten all 64 cube/anti-cube bits in Fez and finished the game, but there are two doors which remain inaccessible to me. The 64-bit door under the little tree island, and the door underneath the main warp gate.
I've already reduced the flow at the waterfall, of course, but I can't find anything else which will allow me to lower the water a little bit more so I can reach these two rooms.
The 64-bit door even opens when I approach, but the water is just high enough that I'm swimming, and entering the door is impossible (i.e. the Up key does nothing).
What do I do? I've looked through a dozen walkthroughs, to no avail!

It is possible to partially lower the water if you are not rotating corresponding lever to the very end. Check if you have used it to the end.
