He discovers that the lake has been drained as a result of Morpha's curse. Later, after the young hero turns into an adult by pulling the Master Sword from its pedestal, Link returns to find the lake almost drained of its rich waters. Link first visits the lake as a child while looking for Princess Ruto, where he finds Ruto's Letter encased in a bottle at the bottom of the lake. Other notable features of Lake Hylia include the Lakeside Laboratory, where various experiments are conducted to discover the lake's mysteries, and the Fishing Pond, where Link can fish for an unlimited time for just 20 Rupees. Also on the shore of Lake Hylia are two Scarecrows named Pierre and Bonooru, the latter of which helps Link obtain the Scarecrow's Song.
As such, it is possible to reach the lake by floating down the river from Gerudo Valley. All of the lake's water comes from Zora's Fountain, passing through Zora's River, then Gerudo Valley, and eventually reaching Lake Hylia.
The lake is made up of various islands, with the largest one bearing a lone tree as well as the Triforce Warp for the ' Serenade of Water.' It is connected to Hyrule Field and has an underwater tunnel that serves as a shortcut to Zora's Domain, although it is blocked by ice once Link turns into an adult. In Ocarina of Time, Lake Hylia is located in the southern region of Hyrule and is home to the sunken Water Temple, which is used by the Zoras to worship the water spirits.
