RESERVOIR STORAGE MONITORING SYSTEM

Posted On: 21 JUL 2025 4:02PM by PIB Delhi

Central Water Commission (CWC) monitors live storage capacity of important reservoirs of the country and issues weekly bulletin. Prior to Reservoir Storage Monitoring System (RSMS), the data was collected from the respective project authorities through phone calls and fax. The collected data was then analyzed manually Based on the analysis and results, the reports were prepared and bulletins issued.

To streamline the process of data entry and generation of bulletin, the RSMS was introduced in 2012. In RSMS, user id and passwords have been allocated to project authorities and regional offices of CWC. They enter their data directly by logging into RSMS. Data analysis and bulletin generation is done with the help of RSMS and the soft copy of the bulletin sent through email to all concerned Union ministries, respective State governments and other stakeholders. This bulletin is also uploaded on RSMS portal for view/use of public at large. This open access to information supports informed decision making. It enables better planning for irrigation, drinking water, and flood control, while also aiding drought preparedness.

As on date, live storage status of 161 important reservoirs in the country is being monitored by CWC. The cumulative live storage capacity of 161 reservoirs is 182.46 Billion Cubic Metre (BCM). State and UT-wise cumulative live storage capacity of monitored reservoirs is given below.

The RSMS portal was developed in-house by CWC. No separate budgetary allocation made for development and maintenance of RSMS since its inception.

The storage of 161 key reservoirs across the country is being monitored on RSMS, with comprehensive bulletins released on a weekly basis to inform stakeholders and support water resource management.
