How this is worked out: for each gauge Flowcast compares the latest USGS flow reading with the reading closest to 24 hours earlier (it must be within 3 hours of that time). A change of +10% or more is labelled rising, −10% or more falling, and anything in between steady. “n/a” means there was no current reading or no reading near 24 hours earlier. USGS readings are provisional. This describes the last 24 hours only; it is not a forecast, and dam releases can change flow on regulated rivers at any time.
