Crest stages and dates are the National Weather Service's own (National Water Prediction Service gauge data), shown only for gauges whose NWS forecast point lists the same USGS gauge number. Stages are in feet on each point's own NWS datum. Crests NWS marks as an older datum, and preliminary crests, are left out; only official and record crests are listed. These describe flooding history, not fishing or boating safety; Flowcast's Fishable/Floatable status is never based on them. Gauges not listed have no NWS crest history that passed these filters.

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.
