What is US Lower 48 Natural Gas Working Storage (EIA weekly) (GAS_STORAGE_US_L48)?

US Lower 48 Natural Gas Working Storage (EIA weekly) is a weekly inventory level published by the US Energy Information Administration (EIA) — the volume held in storage at the end of the reporting week, not a price.
