Note: We estimated end-of-month values for March from the Weekly Natural Gas Storage Report.

We estimate the Lower 48 U.S. states began this natural gas injection season (April–October) with 1,890 billion cubic feet (Bcf) of working natural gas in storage, based on interpolated data from our Weekly Natural Gas Storage Report. This level was 3% above the previous five-year (2021–25) average and 3% above last year’s end-of-season storage volume.
