In reality, Tasik Chini is less a lake and more a naturally dammed tributary of the mighty Pahang River, which lies to the north. Until recently the water of the lake rose and fell with the seasons - during the wet season the water was unable to flow down the narrow Sungai Chini and so became backed up into a series of lakes. A unique ecosystem developed, dominated by the presence of the Sacred Lotus Nelumbo Nucifera, which once covered the entire surface of the lake system.

During low water the lotus seeds would germinate, the roots take hold in the soft mud and the stunning blooms would appear on the water's surface.

During monsoonal floods, from October to January the lotus would die but with the flowers having been fertilised, new seeds would litter the lake bottom awaiting the dry season.

In 1995 the authorities, in a bid to make the lakes more appealing to visitors in the dry season, built a dam at the point where the Sungai Chini enters the Pahang River. The waters were then never able to recede again. It was not long before the ecosystem started showing signs of stress.

The lotus became fewer and fewer with the passing years, and large stands of various species of Eugenia trees, which border the lake also died back, being unable to tolerate constant submergence.

Happily, the mistake has been rectified; in early 2000 the dam was breached and redesigned to accommodate the annual rise and fall of the waters. The lotus are returning once again, however it will be decades before the hurt is healed.
