The 'live storage capacity' of a reservoir is:
Choose the correct answer
Total volume of the reservoir
Usable storage between minimum pool level (dead storage level) and full reservoir level (FRL)
Volume of dead storage only
Volume above flood level
Correct Answer
B. Usable storage between minimum pool level (dead storage level) and full reservoir level (FRL)
Why is this the answer?
Live (active) storage: volume between minimum pool level (MWL at dead storage) and FRL (Full Reservoir Level). This is the usable storage for irrigation, power, water supply. Dead storage: below minimum pool level — not usable (silts collect here). Total storage = dead + live + flood (between FRL and MWL). Reservoir capacity from mass curve.
