Whitewater kayaking
Estimated population-level acute risk associated with whitewater kayaking on rivers with rapids.
Base risk estimate
0.8 micromorts per hours
Population-level estimate. Not a personal prediction.
Assumptions
Assumes whitewater kayaking on class III–IV rapids with appropriate safety gear and paddling experience.
Limitations
Whitewater/flatwater split is estimated, not directly measured in USCG data. Risk varies significantly by rapid class, water level, swimmer rescue difficulty, protective gear, and experience level.
Source notes
USCG 2022: ~89 kayak fatalities total. Whitewater kayaking involves higher per-hour risk than flatwater due to more hazardous conditions. The combined USCG-derived rate of ~0.45 micromorts/hour is adjusted upward to 0.80 for whitewater, reflecting that whitewater participants have smaller exposure hours but account for a disproportionate share of deaths. USCG data does not separate flatwater from whitewater.
