Last reviewed on October 3, 2026. Figures below are a snapshot of the EIA release of October 1, 2026 and are updated by hand — always check the EIA Weekly Natural Gas Storage Report for the newest number.

Regional breakdown (week ending September 25, 2026)

The EIA splits the Lower 48 into five storage regions. South Central is further divided into salt-cavern and non-salt facilities; salt caverns can cycle gas in and out quickly, so they often swing the most from week to week.

Weekly storage history, 2026

Stock levels are taken from the EIA's historical series as published with the October 1, 2026 release; the EIA occasionally revises or reclassifies past weeks, so a few values can differ slightly from the figure announced on the original release day. Five-year averages and year-ago values are the EIA's published comparison values for each 2026 report week.

What the weekly report contains

The Weekly Natural Gas Storage Report estimates how much working gas sits in underground storage in the Lower 48 states at the end of each week (Friday), based on the EIA-912 survey of storage operators. It shows:

• Stocks for the current and previous week, nationally and for each of the five regions (East, Midwest, Mountain, Pacific, South Central).
• Net change — the injection (positive) or withdrawal (negative) in Bcf. This is the headline number the market trades.
• Implied flow — the physical injection or withdrawal after removing any reclassifications or revisions to earlier data. Usually it equals the net change.
• Comparisons with the same week a year ago and with the five-year average, in Bcf and percent.

Because traders build their own estimates from weather, production and demand data, prices react to the gap between the reported change and the market consensus rather than to the number itself. For a full walkthrough, read our guide to U.S. natural gas storage and how to read the report.

Seasonal pattern: injection and withdrawal seasons

Storage normally falls from November through March as heating demand exceeds production and rises from April through October. The table below shows how low inventories fell each spring and how high they climbed each autumn in recent years, using EIA weekly data.

Some useful reference points from the EIA's five-region history, which starts in 2010:

• Highest weekly level: 4,047 Bcf (week ending November 11, 2016).
• Lowest weekly level: 824 Bcf (week ending March 28, 2014), after the cold 2013–14 winter.
• Largest weekly withdrawal: 359 Bcf, reported for the weeks ending January 5, 2018 and January 30, 2026.
