What are the different storage zones in a reservoir?

Reservoir storage zones from bottom up: Dead storage - below lowest outlet, stores sediment, cannot be used. Active/live storage - between dead storage level and normal pool level, for water supply, irrigation, or power generation. Flood control storage - between normal pool and maximum pool levels, reserved for temporary flood detention. Total storage includes all zones. Reservoir operation rules balance these uses. Sedimentation gradually fills dead storage, eventually affecting active storage if not managed.
