This project deals improved dam water management mechanism. The flood which is caused due to sudden release of dam water is prevented by continuously monitoring the dam and transporting the water from one dam to another if necessary. People in the world get affected because of flood in winter and water scarcity in summer. Reservoir is the most efficient tool to save the water resources. The water in reservoirs can be used for domestic and industrial purpose, irrigation, hydropower generation, navigation, ecology, boating, fishing and other forms of recreational activities. But it gets wasted in the form flood. Hence a prototype is constructed more efficiently to save the life of people and environment from flood impacts and also to save the water resources. It is a low cost automated control system which provides better accuracy. Here the data is analyzed and controlled by Arduino Uno R3. This automatic control system is completely programmed. The data is communicated from one dam to another dam through master controller and the communication between the master controller and dams takes place wirelessly using RF Transmitters/Receivers. The master controller has an LCD display to output visual information.
