The Telta Lake is a body of water found just north of Kakariko Village. The lake is filled with fish, with numerous Hyrule Bass, Armored Carp, and Staminoka Bass found throughout. A Raft can be found at the north end of the Lake, making for easier navigation.
There are two treasure chests found in the lake, buried at the sea floor. One near the center of the Lake contains an Opal gem, with another just to the northeast containing ten Arrows. At the far southwest end of the lake, there is a small cave with two small statues. Drop an Apple as an offering to get a Korok Seed.
