Tannin-Colored Water of The Oparara River, New Zealand

Reddish-brown water in a lush forested setting with tea trunks, vines, and green foliageView Full Resolution

The Oparara river in New Zealand is famous for having tannin-stained waters that produce this vibrant reddish color pictured here, and deep yellow hues in other places.

This same phenomenon occurs in other climates, including much of the temperature U.S., where decaying leaves and other organic matter leaches tannins into the water. The color is usually not quite as striking as that pictured here though.
