About Wavetrain · hello@thewavetrain.com

Wavetrain is an early build. Flow readings are USGS provisional data and may be revised. Runnable ranges and run details are drafts for paddlers to review. Permit dates and rules come from the agency pages linked on each permit and can change. Snowpack figures come from NRCS SNOTEL stations, are provisional, and are grouped into basins by watershed, so they may differ from official NRCS basin reports. Nothing here replaces scouting, local knowledge or a conversation with a nearby outfitter.
