How this is worked out: on every run Flowcast saves each gauge's latest USGS flow reading and its status; the last run of each day is kept as that day's snapshot (times are when the run finished, not exact reading times). This page compares the oldest snapshot in the last 7 days (Oct 24, 2026, 7:07 PM PDT) with the latest one (Oct 30, 2026, 11:23 AM PDT), about 5.7 days apart. Change is (latest flow − earlier flow) ÷ earlier flow. Rising or falling here means a change of 10% or more either way. “n/a” means the gauge had no snapshot reading at one end (for example it was added to Flowcast later, or had no current reading). Two snapshots can miss peaks in between, USGS readings are provisional, and dam releases can change flow on regulated rivers at any time. This describes the past week only; it is not a forecast. The window moves forward one day each day.

Data from the U.S. Geological Survey (USGS). Readings are provisional and subject to revision. Flowcast statuses are automated comparisons with each gauge's own history, not safety ratings or fishing reports. Check local conditions, weather, regulations and closures before you go. Rivers can change quickly.
