After you beat the Water Temple, then the lake fills up due to the rain. But first you need the Hookshot, metal boots, and the bow. The hammer helps as well.
you have to complete the dungeon at the bottom of lake hylia
Get the silver scale in Zora's Domain, then go to Lake Hylia through the warp door. The letter is near the door at the Lake Hylia end.
He's at Lake Hylia. You summon him by playing the Scarecrow's Song at special places in dungeons.
Do the Zora diving game. Win it. The you will get the Silver Scale that allows you to dive deeper. It allows you to dive for 6 seconds. That will allow you enough time to dove to the bottom of Lake Hylia to get the bottle.
You have to get princess ruto's message from lake hylia and show it to king zora and he will move.
You learn it at Lake Hylia. As child Link, go up to one of the scarecrows and take out your ocarina. They'll teach you the Scarecrow's Song, which you compose yourself.
Inside Jabu Jabu's belly to get there. You have to get the bottle under water at Lake Hylia and show it to him.
Go to Lake Hylia. Swim out to the island in the middle with a plaque that reads, 'When water fills the lake, shoot for the morning light.' Turn. There should be a small building on a small outcropping of land with a poster of a fishing pole on its side.
If you mean in the Wind Waker, then he is at the back of outset island, you have to blow up a cracked wall to get in, but if you mean in the ocarina of time, then he is in the lake area behind the zora king, you have to give the king rutos note that you get in lake hylia to make you let him pass
You can get the golden scale by going to the fishing pond near Lake Hylia as an adult and catching a fish that weighs 15lbs. This is easier to do during the morning or when it's raining. In order to reach the fishing pond as an adult you should have planted a bean plant next to the house near the entrance of Lake Hylia as a child. However, I remember being able to get up there somehow before...
in lake hylia - ocarina of time - there are two pieces of heart you can get from the laboratory. one is on top of the roof and up the ladder. the other you can get by diving really far down while inside the building. but first you have to get the golden scales by catching the largest fish in the fishing pond. you can only get the largest fish by becoming an adult and completing the water temple. once you have the golden scales you can dive deep enough for the old freaky man to give you a piece of heart.
depends on the game. In ocarina of time you find the fire arrows at lake hylia, the ice in the gerudo training grounds. In wind waker the queen fairy gives them to you. In majora's mask you find fire in the snowhead temple and the ice arrows at the great bay temple
They come with the bow, which can be found in the forest temple. Other arrows: Fire Arrows (go to lake hylia and fire an arrow at the sun as it rises), Ice Arrows(complete the gerudo training ground), and Light Arrows(given to you before entering ganon's castle and beating the game).
