Lake Rotomahana
Rotomahana means "warm lake". Prior to the Tarawera eruption, this lake comprised two smaller lakes - Lake Rotomahana (warm) and Lake Makariri (cold).
Lake Rotomahana was the site of the geothermal "Pink and White Terraces", once considered the eighth wonder of the natural world. The terraces were destroyed in the 1886 Tarawera eruption, which also substantially altered the lake. Today, it is the deepest of the Rotorua lakes and is said to contain the purest strain of rainbow trout in the world.
