What is a run?
A run is a defined section of river with a put-in and take-out. It's the atomic unit of H2OFlows — everything else (rapids, flow ranges, conditions reports, hazard warnings) attaches to a run.
Glossary note: The app uses the term run everywhere. Internally the database and API use reach — a standard hydrology term. They mean the same thing.

Data provenance
Run data is seeded using AI (Claude) from guidebook knowledge, American Whitewater records, and community trip reports. Every item carries a data_source field:
| Source | Meaning |
|---|---|
ai_seed | Generated by AI seeder, pending verification |
import | Imported from a KMZ file |
maintainer | Manually authored, high confidence |
community | Contributed and verified by community |
AI-seeded items below confidence 50 are dropped at generation time. Items at or above 85 are auto-verified. Items in the 50–84 range are stored as drafts and shown with a confidence badge until a community member verifies them.
Finding runs
Use the Explore page to browse runs on a map. Filter by region, class rating, or whether flow data is available. Click any run pin to open its detail page.
Runs also appear as linked items on gauge cards in the dashboard when a gauge is associated with one or more runs.
