Synosis Points
1
This Indian Standard was first published in 1974. Since then considerable developments in the techniques of reservoir operations had taken place. The concept of operation of reservoir considering it as a single entity had given way to the concept of integrated operation of reservoirs. First revision of this standard was taken up in 1994 to include application of system engineering methods, such as mathematical optimization and simulation which were increasingly used for defining, evaluation and selection of reservoir operation policies.

This revision (second revision) has been brought out to bring the standard in the latest style and format of the Indian Standards. In addition, the following major changes have been incorporated:
a) A new clause on hydropower has been incorporated to outline the operation principles of reservoirs designed for power generation, emphasizing water level management for flood and sediment control, particularly in high-flow and low-flow periods.
b) Clause on flood control zone has been modified to clarify its typical range, specifying that it lies between the Full Reservoir Level (FRL) and a predefined level between the FRL and the Minimum Drawdown Level (MDDL) or Dead Storage Level (DSL).

c) New clauses have been incorporated to enhance real-time reservoir operation by including downstream warning system, flood simulation studies, inundation mapping, and a comprehensive Early Warning System (EWS) for disaster risk reduction, particularly in the Himalayan region.
d) Clause on data collection and analysis has been modified to include various data transmission media, including GSM/GPRS communication, Radio Wave communication, and VSAT communication systems, to emphasize the diverse options available for efficient data communication.
