Physico-Chemical Characteristic in Difference Lakes of Malaysia

The objective of this study is to assess the physico-chemical characteristic of five selected lakes in Malaysia. The depth of the selected lakes range between 4 m and 100 meter. The selected lakes with increasing depth are Sembrong Reservoir, Bekok Reservoir, Dayang Bunting Lake, Sg Terip Reservoir and Kenyir Reservoir. Measurements were carried out at three sites in all lakes using a multi-parameter probe. The main parameters studied include temperature, dissolved oxygen, pH and chlorophyll-a. Additionally, water samples were also collected near surface for analysis of total phosphorus. Temperature-depth profile indicate that stratification of temperature was only apparent in deeper lake such as Kenyir. Stratification of dissolved oxygen was observed in most lakes despite their depth variation. Chemical stratification in the studied lakes was likely influenced by geological and chemical processes. Shallower lakes were observed to have higher nutrient concentration compared to deeper ones.
