Thank you for visiting this website which is maintained by the Hydrology and Water Resources Division of the Department of Irrigation and Drainage (DID), Malaysia. The hydrologic data is updated at regular intervals (hourly to daily) from over 300 Remote Telemetry Units (RTUs) located at strategic points nationwide. Data is transmitted by various means depending on the most reliable system of telecommunication such as UHF, VHF, telephone or satellite. The Master Telemetry Unit (MTU) in each state DID office receives and displays the data for local use. An automatic emailer program in each state DID office sends all the data through the internet to the Hydrology and Water Resources Division of DID in Kuala Lumpur that operates a Centralized Flood Monitoring System (See Diagram).
 
Heavy rains and the subsequent high river flows are the major causes of flooding and landslides. The Online rainfall data displayed through this website are useful indicators of potential flooding or landslides. The Online river level data at key flood warning stations of DID provide online information on flooded areas and highways. While DID strives to give the public the most updated data, there will be times when data transmission problems will be encountered. Please use the data in this website with discretion.
