Another 22 are Moderate, and 12 are Very High, with none in Low. Since 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. Fire record ## Where the fires _actually were_ The 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. Several very large fires also affected land partly in Lassen County, including Dixie (2021) at 963,309 acres and Sugar (2021) at 105,076 acres. The 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. ![Rush Fire (2012) in Lassen County, California - Rush Fire , Lassen County, California](/images/wildfire-risk/lassen-county/photos/rush-fire-blm.webp) **Rush Fire, 2012** — Lassen County.

Perimeters are simplified for display; acreage is the figure the source records. Communities ## Where in the county you are _matters most_ Among the listed communities, the higher overall wildfire risk scores include Doyle (72.5), Patton Village (72.1), and Johnstonville (66.1). Susanville, the largest city listed, is 65.2, which sits in the same general range as other nearby communities like Spaulding (61.4). Lower 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. Doyle village · 536 people 72.5 _High_ Patton Village village · 632 people 72.1 _High_ Johnstonville village · 973 people 66.1 _High_ Susanville city · 12,816 people 65.2 _High_ Spaulding village · 206 people 61.4 _High_ Janesville village · 2,461 people 55.8 _High_ Westwood village · 2,150 people 53.7 _High_ Herlong village · 237 people 53.6 _High_ Bieber village 52.4 _High_ Standish village 48.3 _Moderate_ The 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. Terrain & fuels ## Terrain, vegetation and _fuels_ Terrain 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. Vegetation 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. Taken 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. 55 median terrain score (max 65 near Doyle) 74 median vegetation & fuels score (max 80 near Doyle) Fire weather ## Fire weather across _Lassen County_ Fire 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. Separate 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. 54.8 lowest fire-weather score — near Westwood 64.4 highest fire-weather score — near Standish What drives it ## Which part of the risk _moves_, and which doesn't Risk is not uniform inside Lassen County. The highest scored location is 81.1 near Standish, but the lowest is 33.1 in Bieber. Among named communities, Doyle (72.5) and Patton Village (72.1) are on the higher end, while Bieber (52.4) is lower. Even in the Susanville area, scores are mixed: Johnstonville is 66.1 and Susanville is 65.2, while Janesville is 55.8. Each 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.

Source: USFS Wildfire Risk to Communities v2.0 (ImageServer, county extent). CAL FIRE has no mapped Fire Hazard Severity Zone at **92** of the 160 sampled points — the zones cover Local Responsibility Areas, and most of this county is state or federal land. At **92** of them the USFS grid above supplied the hazard reading instead. 160 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. For a property ## What a county range means for _one address_ Two 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. Fire 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. For 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. Across 160 sampled points in Lassen County, the score runs from 33.1 to 81.1 — two neighbouring parcels can sit in different tiers. A county number is the middle of that spread; it says nothing about which end yours is at.

Yes. Since 1984, 884,742 acres have burned, equal to 29.5% of the county. What tier is most common in Lassen County? High 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. What is the most recent large fire named for this county? Biscar (2026) is the most recent large fire, at 69,352 acres. The largest listed fire is Rush (2012) at 315,512 acres. Is fire weather the same thing as burn probability? No. 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. This page is generated from a Lassen County data pack assembled on 2026-08-19 (pack v1.0). Scores are sampled across the county, not measured at any individual address, and are informational decision support — not a substitute for official evacuation orders, a fire-agency hazard determination, or an insurer's underwriting judgement.
