Beneath the dark waters of Caddo Lake, where cypress trees rise like ancient sentinels and Spanish moss drapes so thickly it nearly blocks out the sun, most people have no idea what lies beneath them — one of the largest natural gas deposits on the entire planet. The Haynesville Shale holds enough recoverable natural gas to meet total United States demand for approximately eighteen months, accounts for roughly fourteen percent of all domestic gas production, and was just named by the U.S. Geological Survey as the largest continuous natural gas assessment it has ever conducted anywhere in the country. For mineral owners in northwestern Louisiana and East Texas, understanding what that means has never been more important.
