The lowest scored location is 33.1 in Bieber, while the highest is 81.1 near Standish, so conditions vary a lot by location.\n\n[Score my Lassen County address →](#score-my-address) [How risky is this county? ↓](#risk-at-a-glance)\n\nBefore 20002000s2010s2020sCommunity\n\nLassen County — the largest fires on record, at their perimeter centres, with the county’s main communities.

Another 22 are Moderate, and 12 are Very High, with none in Low.\n\nSince 1984, 884,742 acres have burned in the county, which is 29.5% of county area. That burn history is a major part of how risk is distributed today.\n\nFire record\n\n## Where the fires _actually were_\n\nThe largest fire listed for this county is Rush (2012) at 315,512 acres. The most recent large fire is Biscar (2026) at 69,352 acres.\n\nSeveral very large fires also affected land partly in Lassen County, including Dixie (2021) at 963,309 acres and Sugar (2021) at 105,076 acres.\n\nThe record also includes many other incidents over time, with 328 fire perimeters mapped since 1984. That history helps explain why some nearby areas score very differently from one another.\n\n![Rush Fire (2012) in Lassen County, California - Rush Fire , Lassen County, California](/images/wildfire-risk/lassen-county/photos/rush-fire-blm.webp)\n\n**Rush Fire, 2012** — Lassen County.

Perimeters are simplified for display; acreage is the figure the source records.\n\nCommunities\n\n## Where in the county you are _matters most_\n\nAmong the listed communities, the higher overall wildfire risk scores include Doyle (72.5), Patton Village (72.1), and Johnstonville (66.1).\n\nSusanville, the largest city listed, is 65.2, which sits in the same general range as other nearby communities like Spaulding (61.4).\n\nLower scores among the listed places include Standish (48.3), Bieber (52.4), and Herlong (53.6). For buyers and owners, that spread means location inside the county matters as much as county averages.\n\nDoyle village · 536 people\n\n72.5 _High_\n\nPatton Village village · 632 people\n\n72.1 _High_\n\nJohnstonville village · 973 people\n\n66.1 _High_\n\nSusanville city · 12,816 people\n\n65.2 _High_\n\nSpaulding village · 206 people\n\n61.4 _High_\n\nJanesville village · 2,461 people\n\n55.8 _High_\n\nWestwood village · 2,150 people\n\n53.7 _High_\n\nHerlong village · 237 people\n\n53.6 _High_\n\nBieber village\n\n52.4 _High_\n\nStandish village\n\n48.3 _Moderate_\n\nThe score is the median of the sampled points nearest that community — a community-scale indicator, not a score for any individual property in it. Population comes from the community's own record where the source carries one.\n\nTerrain & fuels\n\n## Terrain, vegetation and _fuels_\n\nTerrain scores are fairly tight in Lassen County, from 55.0 near Doyle to 65.0 at Doyle. That means slope-related exposure contributes, but it does not separate places as sharply as some other factors.\n\nVegetation and fuels vary much more: the lowest scored location is 20.0 in Susanville, while the highest is 80.0 near Doyle. The county’s middle value is 74.0, so fuels are an important contributor in many locations.\n\nTaken together, terrain is relatively steady while fuels change more from place to place. That pattern is associated with why nearby communities can land in different risk tiers.\n\n55 median terrain score (max 65 near Doyle)\n\n74 median vegetation & fuels score (max 80 near Doyle)\n\nFire weather\n\n## Fire weather across _Lassen County_\n\nFire weather was measured across the county, and the scores run from 54.8 near Westwood to 64.4 near Standish, with a middle value of 62.5. That is a narrower spread than several other wildfire risk factors.\n\nSeparate from fire weather, the USFS Wildfire Risk to Communities model reports a mean annual burn probability of 1.07% for the county, with a 90th-percentile cell at 1.94%. It also indicates that 97% of the county is in places that can burn.\n\n54.8 lowest fire-weather score — near Westwood\n\n64.4 highest fire-weather score — near Standish\n\nWhat drives it\n\n## Which part of the risk _moves_, and which doesn't\n\nRisk is not uniform inside Lassen County. The highest scored location is 81.1 near Standish, but the lowest is 33.1 in Bieber.\n\nAmong named communities, Doyle (72.5) and Patton Village (72.1) are on the higher end, while Bieber (52.4) is lower.\n\nEven in the Susanville area, scores are mixed: Johnstonville is 66.1 and Susanville is 65.2, while Janesville is 55.8.\n\nEach bar is what one part of the score covers across Lassen County, on the same 0–100 scale. A long bar is a part of the risk that depends on where you are; a short one is the same almost everywhere.\n\nTerrain\n\n55–65 highest near Doyle\n\nVegetation & fuels\n\n20–80 highest near Doyle\n\nHazard zone\n\n10–91.7 highest near Spaulding\n\nFire history\n\n5–95 highest near Doyle\n\nFire weather\n\n54.8–64.4 highest near Standish\n\nOverall score\n\n33.1–81.1 highest near Standish\n\nThe tick on each bar is the middle value.

At **92** of them the USFS grid above supplied the hazard reading instead.\n\n160 sample points on a ~2.3 km grid, plus one at the centre of each community, weighted with the Satelife county profile v1 · median layer coverage 100%. Scores are 0–100 and comparable within the county, not across states.\n\nFor a property\n\n## What a county range means for _one address_\n\nTwo mapped factors that often matter at property scale are hazard zone and local fire history, and both vary sharply here. Hazard zone scores range from 10.0 in Herlong to 91.7 near Spaulding, with a middle value of 70.0.\n\nFire history also has a wide spread, from 5.0 in Herlong to 95.0 near Doyle. The county middle value is 40.0, which reflects substantial differences in past fire footprint between locations.\n\nFor countywide context, FEMA’s National Risk Index rates Lassen County’s wildfire risk as Relatively Moderate and its expected annual wildfire loss as Relatively Moderate. FEMA also rates overall all-hazards risk as Relatively Low for the county.\n\nAcross 160 sampled points in Lassen County, the score runs from 33.1 to 81.1 — two neighbouring parcels can sit in different tiers.

Since 1984, 884,742 acres have burned, equal to 29.5% of the county.\n\nWhat tier is most common in Lassen County?\n\nHigh is the most common tier among the places we scored, with 126 locations in High. There are also 22 Moderate and 12 Very High locations, and none in Low.\n\nWhat is the most recent large fire named for this county?\n\nBiscar (2026) is the most recent large fire, at 69,352 acres. The largest listed fire is Rush (2012) at 315,512 acres.\n\nIs fire weather the same thing as burn probability?\n\nNo. Fire weather scores describe weather-related wildfire exposure, while burn probability here comes from the USFS Wildfire Risk to Communities model. In this county, that model reports 1.07% mean annual burn probability and 1.94% at the 90th-percentile cell.\n\nThis page is generated from a Lassen County data pack assembled on 2026-08-19 (pack v1.0).
