2026 Lyman County, South Dakota Wildfires
All 2026 Lyman County Fires
A fire is listed here when it is located in Lyman 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 Lyman County, not its whole reported size. A fire located elsewhere that burned into Lyman County is listed too, at its Lyman County acres, and is not added to the Lyman County fire counts. County lines come from a different boundary dataset than state lines, so Lyman County's acres are counted along county lines and can differ a little at the edges from the figures on the state page.
No fires are tracked in Lyman County for the 2026 season. This table lists every fire the season statistics count for Lyman County; for 2026 that list is empty. Statistics update with each data-update cycle, which normally runs about every 5 minutes.

Burn severity · Lyman County 2026
Burned acres in Lyman County for the 2026 season, split by how severely each cell of ground burned. Each figure counts the 30 m cells inside a fire's latest mapped perimeter, measured from satellite imagery. The Fires tab carries the reported season acreage.
Severity comes from the differenced normalized burn ratio (dNBR), the same index the federal burn severity programs publish, classified with the standard thresholds.
This is an initial assessment. Trees keep dying for months after a burn, so severity in forest reads conservative until the official assessments arrive after the season.
