How to Complete The Ancient Zora Waterworks

First things first, jump into the water. You'll land in a little pond right in front of some steps. Just swim forward onto dry land.

You'll quickly run into a drain pipe that's blocked. Grab a bomb or equip a weapon with a rock attached to it and smash that pipe open. This is key because it'll raise the water level enough for you to get into the main area of The Ancient Zora Waterworks.

Next up, you'll enter a room with a low water level. Take a look down – you should see some floating planks and the second blockage. Just jump down there and clear it out.

Now, look across the room. You'll spot the third blockage, but this one's a bit trickier since it's up off the ground. See those planks lying around? Use your Ultrahand ability to build a makeshift ladder. Once it's built, climb up and unclog that pipe. That's the fourth blockage done!

After dealing with the third blockage, find the giant pipe. Right near it, you'll see two smaller pipes. You need to climb inside these smaller ones. They'll lead you through the pipe system. Keep your wits about you, though, because some Chuchus might pop out and attack while you're navigating.

Your main goal here is to reach the very center of this pipe network, where you'll notice water pouring down from above. Once you see that pouring water, stand right in the middle and use your Ascend ability. This will shoot you straight up to the fourth blockage. Just hit that one to finish filling the room with water.

Now, head through the pipe you just emerged from. You'll find a lever. Use your Ultrahand to pull it and open the gate.

The final step is to head to the center ruins and interact with the glowing stone table. Doing this will open up the path to the sky islands and send Link back to Sidon. You've cleared it!
