Popis: In recent years, monitoring quality of water body or reservoir has become a main concern for the determination of current condition and long-term pattern for future management. This study focused on hydrology properties and water quality of Sembrong Dam in Johor, Malaysia. The Sembrong dam reservoir is constructed on large lowland rivers with gradually sloping banks, it can be characterized by inundation of large areas, extreme horizontal variability with extensive shallow riparian vegetation and shallow reservoir. The secondary function of the dam was to provide a clean water supply to 240,000 consumers in Kluang district area were used for daily activities. Extrapolation beyond the data is often necessary to provide information needed for dam safety risk assessments. Thus, quality of the water from Sembrong dam important for future. The rainfall data were sourced from the Environmental Impact Assessment (EIA) report and the Department of Irrigation and Drainage, Malaysia whilst reservoir inflow data were extracted using a water balance equation. For water quality study, there were a total of 17 water quality sampling stations. The result indicated that Sembrong River Dam slightly shows high soil loss (487.12 kg/km2/day) where is consist of soft fine grained silty clay material with organic matter, tree roots and decaying timber. For rainfall and evaporation records are 1862 mm and 1098 mm. Sembrong River (Zone A) generally slightly polluted compared Merpoh River (Zone B) where is clear from pollution in Sembrong Dam. Due to Biological parameter where the Sembrong River shows a high of Total Coliform rather Merpoh River. The chemical parameters show that Sembrong River was not a good condition. According to Water Quality Index, Sembrong River was truly slightly polluted compared Merpoh River in Sembrong Dam. As a conclusion, Sembrong dam categorized as Class III according to NWQS
