Zora's River

From Zelda Wiki.org

Zora's River is a river found in Ocarina of Time, A Link to the Past, and Twilight Princess. In A Link to the Past Zora's River can not be swam in unless Link has the Flippers. When Ganon takes over and makes Hyrule into the Dark World the river becomes greenish-black with many foes hiding underneath.

It is the source of Lake Hylia, starting in Zora's Domain, where the Zoras dwell. A few bridges are built over the river, for easy crossing and to allow horses to cross. Zora's River is considered to be the source of all major bodies of water in Hyrule. While Zora's River passed in front of Death Mountain in Ocarina of Time and A Link to the Past, it does not in Twilight Princess.

In Twilight Princess, the majority of Zora's River is used for two mini-games and for capturing Shadow Insects. This part of the river is not accessible by foot and can only be reached in the aforementioned ways. Upper Zora's River, however, is accessible by foot. It is home to Iza, Hena, and Hena's Fishing Hole.
