Plumas County

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Volcanoes within 100 miles

1. U.S. volcanoes within 100 miles, from the USGS Volcano Hazards Program. The threat category is the USGS 2018 National Volcanic Threat Assessment, which ranks volcanoes by how hazardous their past eruptions were and how many people and how much infrastructure lie near them. It is not a forecast of eruption.

Mapped landslides

Mapped by NASA (5), USGS CA Dixie Fire Debris Flows (2).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

More event types since 1996

Costliest events since 1996

1. Sep 1, 2000Wildfire$22.7 million
   National Weather Service narrative

   A wildfire ignited on August 17th...20 miles west of Quincy in the steep terrain of the Feather River Canyon. The fire was pushed by strong winds for several days and significantly impacted Hwy 70 and the Bucks Lake Wilderness area. Only one structure (an out-building) was lost but 46280 acres were burned.

2. Feb 7, 2017Flood$2.0 million
   National Weather Service narrative

   The Middle Fork of the Feather River saw record flooding (a record crest at Portola on the 10th) and caused extensive structural damage in Portola, Clio, and downstream to Blairsden. Highway 89 was closed near Clio due to water over the road. Many schools were closed on the 9th in the Portola area and along the Feather River. Damage estimate only for repairs to Highway 89 (per a CALTRANS report) so actual flooding damage likely much higher.

3. Dec 31, 2005Flood$1.0 million
   National Weather Service narrative

   Mainly rural flooding was reported in Plumas County.

4. Jul 3, 2015Thunderstorm Wind$525,000
   National Weather Service narrative

   Wind damage was focused on Lake Almanor Peninsula and Lake Almanor West with reports of trees into 3 homes, downed power lines, a propane release and other damages. Major damage was done to one home, minor damage to 2 other homes on the Peninsula. Three vehicles were damaged including a Sheriff Deputy patrol car. Many residents suffered mud and debris problems in yards and driveways. Highway 32 was closed near the causeway due to a debris flow across the roadway.

5. Dec 14, 2002High Wind, Lassen/Eastern Plumas/Eastern Sierra$220,000
   National Weather Service narrative

   A strong cold front moving through northern California on December 14 brought near-record nigh winds to northeast California and western Nevada. Wind gusts reports in the 60-80 mph range were common throughout the day across the entire region, with a few gusts near 100 mph. Remote wind sensors along the Sierra Crest measured wind gusts in excess of 130 mph. Strongest winds occurred just before the cold front moved into the area at about 5:30 p.m. Literally hundreds of trees and thousands of tree limbs were blown down across the region. In addition, there was widespread damage to roofs, fences, commercial billboards and signs, and power lines. Numerous power outages occurred, some…
