Prairie du Sac, WI
Prairie du Sac, WI's wildfire risk, in USFS's own numbers
Prairie du Sac sits at the 16th percentile nationally for wildfire risk to structures — among the lower wildfire-risk places nationally — per USFS's Wildfire Risk to Communities model, built from its 1,789 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Prairie du Sac at the 17th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
USFS puts 55.5% of Prairie du Sac's 1,789 buildings in the Indirect exposure zone, versus 6.1% Direct and 38.5% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
