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.
