In 2025, fire departments serving Green River responded to 30 fire and hazmat incidents . Here's the full picture.
Incomplete 2025 data. Green River's departments reported 30 incidents to NFIRS for 2025, against about 65 in a typical year, so 2025 figures on this page undercount. The 2021–2025 totals are the better guide.
Hazardous condition, other lead by count. Building fires lead by dollars. Together the top five categories make up about 63% of all calls.
Aug peaks. Feb dips. Watch for the typical fall climb starting in October.
324 incidents 2021–2025. Peak year was 2023.

| 2022 | 63 | -8.7% | |
| 2023 | 96 | +52.4% | |
| 2024 | 66 | -31.2% | |
| 2025* | 30 | — |
* Well below Green River's usual volume. That almost always means one or more departments didn't submit a full year to NFIRS, not that fires dropped, so no year-over-year change is shown for it.

Numbers reflect incidents reported by participating fire departments to the National Fire Incident Reporting System (NFIRS) Public Data Release for calendar year 2025. NFIRS is voluntary — about 23,000 of roughly 30,000 US fire departments report — so totals are a strong indicator, not a complete census. Per-capita comparisons use 2023 ACS population estimates. Wildland fire data complements NFIRS with NIFC and USFS perimeters. Active-fire counts come from a dated NIFC snapshot, not a live feed.
