Abstract

Tasik Chini is one of the natural lakes in Malaysia, located in the south-east of the Pahang State. It is the second largest natural lake in Peninsular Malaysia comprised of 12 open water bodies (locally known as “LAUT”). It covers an area of 202 ha of open water and 700 ha of freshwater swamp. Tasik Chini is a popular tourist sites due to its beautiful view where water lily flowers are growth and live on the surface of Tasik Chini. Surface water resources have played an important function throughout the history in the development of human civilization. About one third of the drinking water requirement of the world is obtained from surface sources like rivers, canals and lakes (Das & Acharya 2003). Unfortunately, these sources seem to be used as the best place for waste discharge for agriculture, domestics and industries (Nigel 2002). Tasik Chini recently has undergone devastating situation since 1984 or earlier due to the development in the surrounding areas such as mining, oil palm plantation and urbanization. A study carried out by the Malaysian Nature Society (1999) found that there are 288 species of plants, 21 species of aquatic plants, 92 species of birds and 144 species of freshwater fishes. Studies by the Malaysian Wetland International revealed that the barraging of Sungai Chini has created negative impacts on the general health of the ecosystem and surrounding water bodies (UNDP 1999). The condition of Tasik Chini became worst when a barrage was built in 1994 to retain water in Tasik Chini for tourism purposes (Mushrifah Idris & Ahmad Abas Kutty 2005). Negative impacts have been identified as a result of the barraging (Muhd. Barzani et al. 2004), and it was postulated that the barrage has changed the downstream water flow characteristics. This includes degradation of water quality, increase in-lake sedimentation, lake and river bank scouring and the water of the lake had been found to be only safe for recreational purposes (Ahmad Abas et al.2005a). Since 1998, after the barrage was re-structured by reducing the spill design, several problems associated with the low flow in the water level have emerged. This hinders boating navigation in the lake, the loss of diversity in the aquatic species and degradation in the water quality. As a result, the number of local and international tourists visiting Tasik Chini has decreased. The study based on various physico-chemical parameters and heavy metals were carried out in order to identify water quality status of seven feeder rivers before entering Tasik Chini. The study period was from October 2004 to November 2005 for representing two monsoon seasons.
