Float times are calculated using real-time flow data from the USGS Westham gauge and CFS-based velocity modeling proven across hundreds of James River floats.

The model uses base paddling speeds calibrated for each river section (current + paddler effort), then adjusts for live river flow — higher CFS means faster current and shorter float times.

Effort levels: Leisurely (casual pace, frequent stops), Moderate (steady paddling), Athletic (strong sustained effort).

Wind adjustment: Real-time wind speed and direction are factored in — headwinds slow you down, tailwinds speed you up.

Times include the full section including put-in to take-out. Actual times may vary based on group size and stops.
