Notes: This table tracks U.S. natural gas inventories held in underground storage facilities. The weekly stocks generally are the volumes of working gas as of the report date. Changes in reported stock levels reflect all events affecting working gas in storage, including injections, withdrawals, and reclassifications between base and working gas, including information on estimated measures of sampling variability for the most current published estimates of weekly stocks and their net changes.  See Definitions, Sources, and Notes link above for more information on this table.
