All 2026 Lassen County Fires · 11 fires

A fire is listed here when it is located in Lassen County. Each complex is counted once, through its parent: the parent carries the complex's acres, and its member fires are listed beneath it without being counted again. A fire that crossed a county line is listed with the acres that burned in Lassen County, not its whole reported size. A fire located elsewhere that burned into Lassen County is listed too, at its Lassen County acres, and is not added to the Lassen County fire counts. County lines come from a different boundary dataset than state lines, so Lassen County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
