The Ayamura Lakes are a group of lakes found in the central region of the Bird's Head Peninsula in West Papua. The lakes are named after the Ayamaru tribe that lived here for thousands of years. The nearest village to the group is Greemakolo.

Physical Features

The group makes up Lake Ayamaru and Lake Hain. The lakes are surrounded by many low hills. The water in both of the lakes are a clear blue because of the rich material found in the water. There are deep holes in the lakes that lead to underwater caverns. The vivid colors on the north shores of the Ayamaru Lakes are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from orange to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature of the water which favors one bacterium over another. The pH in the lake exeeds to 8.0. On the south shores of the lakes is filled with wetlands and many wildlife.

Lake Ayamaru

The largest lake in the group, Lake Ayamura has a more warm temperature than Lake Hatlin. In the ceter of the lake is Kaymundan Island, a small island filled with trees. On the northwestern shore of the lake is the village of Greemakolo. The lake is a bit foggy because of the temperatures up to 71 F. This is also where the Ayamaru River starts. The people from the surrounding villages use the lake for fishing and bathing.
