The water was colored dark reddish because they contain tannins derived from peat in the surrounding forest. In the rainy season, the depth of the lake water can reach 6-8 meters and cause tergenangnya surrounding forest. However, during the dry season, where the water level in Sungai Kapuas gradually decreased, water from Lake Sentarum will flow into the Kapuas River so that water in the river discharge is relatively stable.
