That pattern lines up with a county that has seen repeated fire activity over time. Fire record ## Where the fires _actually were_ Lake County has had 157 mapped fire perimeters since 1984, and 738,119 acres have burned in that period. In total, 87.2% of the county has burned since 1984. The largest fire listed here is the Ranch Fire in 2018 at 410,202 acres. It is also the most recent large fire in this county record. Other major fires tied to Lake County include the Doe Fire (2020), which burned 589,835 acres and was partly in the county, and the Valley Fire (2015), which burned 76,085 acres and destroyed 1,955 structures. The Rocky Fire (2015), River Fire (2018), Pawnee Fire (2018), Jerusalem Fire (2015), and Fork Fire (1996, partly in county) are also part of the county’s fire history. ![Ranch Fire (2018) in Lake County, California - In a year of record-breaking fires, California scored another record on August 7, 2018, when the Mendocino Complex burst into the ](/images/wildfire-risk/lake-county/photos/california-wildfires-modis-2018-08-08.webp) **Ranch Fire, 2018** — Lake County.

Communities ## Where in the county you are _matters most_ Community-level results show meaningful differences around the county. Spring Valley (79.4), Cobb (78.6), and Midlakes (76.1) are among the higher-scored places listed here. Lower-scored communities include Lucerne at 58.9 and Lakeport at 63.3, while Clearlake is higher at 73.9. These gaps are large enough that two homes in different towns can sit in clearly different wildfire-risk contexts.

Population comes from the community's own record where the source carries one. Terrain & fuels ## Terrain, vegetation and _fuels_ Terrain scores in Lake County are mostly on the higher side, with a county middle value of 65.0. In the places scored, terrain runs from 40.0 in Middletown to 65.0 in Cobb. Vegetation and fuels vary much more. That score ranges from 5.0 in Clearlake Oaks to 80.0 in Middletown, with a county middle value of 74.5. 65 median terrain score (max 65 near Cobb) 74.5 median vegetation & fuels score (max 80 near Middletown) Fire weather ## Fire weather across _Lake County_ Fire weather was measured across the county, and scores are consistently elevated. Values run from 53.8 near Upper Lake to 65.2 in Spring Valley, with a middle value of 63.1. A separate national model from the USFS Wildfire Risk to Communities project reports a mean annual burn probability of 1.88% for Lake County, with a 90th-percentile cell at 4.00%. It also indicates that 95% of the county can burn. 53.8 lowest fire-weather score — near Upper Lake 65.2 highest fire-weather score — near Spring Valley What drives it ## Which part of the risk _moves_, and which doesn't Risk is not uniform across Lake County. Among named communities, Spring Valley is at 79.4 while Lucerne is at 58.9, showing a wide local spread. Several other communities cluster on the higher side, including Cobb at 78.6 and Kelseyville at 76.5, while Lakeport is lower at 63.3. For buyers and owners, that means neighborhood-level differences can be substantial even within the same county. Each bar is what one part of the score covers across Lake 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.

Scores are 0–100 and comparable within the county, not across states. For a property ## What a county range means for _one address_ Two property-relevant factors are especially high in many parts of Lake County: hazard zone and past fire activity. Hazard-zone scores range from 10.0 in Clearlake to 96.3 in Spring Valley, with a county middle value of 90.0. Fire-history scores show a similar pattern of elevated exposure over time. They range from 5.0 in Lucerne to 95.0 in Middletown, and the county middle value is 80.0. FEMA’s National Risk Index rates Lake County’s wildfire risk as "Relatively High" and its wildfire expected annual loss as "Relatively High." FEMA also rates overall all-hazards risk as "Relatively Moderate," social vulnerability as "Relatively High," and community resilience as "Relatively Low." Across 161 sampled points in Lake County, the score runs from 17.6 to 84.1 — 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.
