All 2026 San Joaquin County Fires · 4 fires

A fire is listed here when it is located in San Joaquin 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 San Joaquin County, not its whole reported size. A fire located elsewhere that burned into San Joaquin County is listed too, at its San Joaquin County acres, and is not added to the San Joaquin County fire counts. County lines come from a different boundary dataset than state lines, so San Joaquin County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
