Zora's River

Zora's River is a recurring location in the Legend of Zelda series. Zora's River runs throughout certain areas of Hyrule, the flow of the water coming directly from Zora's Domain, the source of all of Hyrule's water.

The Legend of Zelda: Ocarina of Time
Zora's River runs down from Zora's Fountain and Zora's Domain, west across Hyrule Field, through the narrow gorge in Gerudo Valley, and finally empties out into Lake Hylia and various other small lakes and streams along the way. The river is very important to the people of Hyrule because it is the country's largest source of fresh water. Because of this, the King of Hyrule entrusted the Zora race to protect Zora's Domain and prevent anyone from tampering with Hyrule’s largest water supply.

The Legend of Zelda: Twilight Princess
When Link first arrives at Zora's River, it is dried up because Zora's Domain is frozen solid. When Link and Midna thaw Zora's Domain through use of a Twilight Portal, the river returns to normal. Later in the game, Link can find some Shadow Insects in the area.

Initially, Link must call a Shadow Kargaroc in order to fly up the river. There, Link will find some Shadow Beasts and, consequently, a Twilight Portal. Link must later use the Shadow Kargoroc again to get Lanayru's Tears of Light, after which Zora River, Lake Hylia, and Zora's Domain are restored to their usual state.

Later, when Link has dispelled the Twilight, he can play a game very similar to taking the Shadow Kargoroc up the river. This time, however, he howls next to Hawk Grass in wolf form to call a normal Kargoroc. This game, run by a bird named Plumm, is played by controlling the monster bird to fly into balloons to earn points.

Iza's Rapid Ride located at the Boat Rental Cabin in Upper Zora's River also has Link canoeing down the Zora's River.
