About Riverable
Riverable was created by avid paddlers and hydrology data specialists to answer a simple, essential question: "Is the river safe and flowing right today, or will we scrape bottom?"
Demystifying Streamflow Telemetry
For decades, recreational river enthusiasts—tubers, kayakers, canoeists, packrafters, and fly fishermen—had to navigate dense government tables, decipher obscure station IDs, and guess whether 350 CFS meant a gentle family float or a bony, bottom-scraping drag.
Riverable synthesizes raw scientific telemetry from the United States Geological Survey (USGS) with localized atmospheric forecasts, watershed precipitation accumulation, and craft-specific hydrodynamic models to give river runners immediate, actionable clarity.
Our Scientific Data Stack
We rely strictly on reputable public scientific agencies and open meteorological infrastructure:
- USGS Water Services (NWIS): Real-time streamflow discharge (CFS), gauge height (stage in feet), and water temperature (°C/°F) across 2,200+ instantaneous monitoring stations throughout the United States.
- NOAA / National Weather Service (NWS): River flood stages, crest forecasts, and severe hydrologic alerts.
- Open-Meteo: High-resolution atmospheric modeling, ambient air temperature, wind velocity, and trailing 7-day watershed precipitation totals.
- OpenStreetMap (Overpass API): Public boat ramps, canoe launches, egress take-outs, and livery coordinates.
- RainViewer: Real-time Doppler weather radar composite overlays for tracking incoming storm cells.
Floatability Score Methodology
Our proprietary 1 to 10 Floatability Score evaluates river safety and comfort across four distinct activity profiles:
Optimal: 150–500 CFS. Low water (<100 CFS) causes scraping; high flows (>500 CFS) create entrapment and strainer hazards. Water below 55°F triggers cold shock caps.
Optimal: 250–1,200 CFS. Balanced depth and current for touring boats with easy maneuvering around gravel shoals.
Optimal: 800–3,500+ CFS. Fast continuous current, standing waves, and hydraulic features requiring technical paddling equipment.
Optimal: 100–600 CFS. Safe wadeable current velocities, stable hydrograph curves, and high water clarity for active insect hatches.
Provisional Telemetry Subject to Revision
Real-time streamflow discharge data from the USGS is transmitted automatically via satellite and cellular telemetry at intervals ranging from 15 to 60 minutes. As explicitly noted by the USGS, "Data are provisional and subject to revision until they have received final review and approval by qualified hydrographers." Ice buildup, flash channel scour, or backwater effect from debris can occasionally cause instantaneous readings to diverge from actual river conditions.
Editorial Standards & Corrections Policy
River safety depends on accuracy. Our content is compiled and reviewed by the Riverable Hydrology & Editorial Team, cross-referencing official hydrographic data with established paddling guidebooks and American Whitewater safety guidelines.
If you spot an error, outdated put-in information, changed parking access, or an inaccurate flow sweet spot on any river reach, we want to know immediately. We investigate and apply corrections within 24 to 48 hours.
