Notes: Data for 1997 through 2001 are final. All other data are
preliminary unless otherwise noted. See Explanatory Note 6 for
discussion of the reporting of underground storage information. Gas in
storage at the end of a reporting period may not equal the quantity
derived by adding or subtracting net injections or withdrawals during
the period to the quantity of gas in storage at the beginning of the
period. This is due to changes in the quantities of native gas included
in base gas and/or losses in base gas due to migration from storage
reservoirs. Totals may not equal sum of components because of
independent rounding. Geographic coverage is the 50 States and the
District of Columbia. Positive net withdrawals indicate the volume of
withdrawals in excess of injections. Negative net withdrawals indicate
the volume of injections in excess of withdrawals.
