River Levels: Gauge Log

River levels with the source, station ID and observation time beside each reading, plus a plain-language view of rises, falls and daily ranges. ▶ KNOW THE SOURCE • See the agency, station ID, observation time and elapsed minutes beside each reading. • Check the raw provider value and unit, measurement reference and Provisional or quality status. • Open the provider station page and data attribution from the gauge detail. • Gauges keeps cached readings between visits and labels older values Last known reading. ▶ READ THE RISE OR FALL • Read Rising, Falling or Steady, with a rate per hour from the last 3 hours when enough observations are available. • See the 24-hour minimum and maximum alongside the current reading. • At supported US gauges, compare the level with agency stages when the station and vertical reference match. • Inspect a 7-day observation chart; breaks show missing samples. ▶ KEEP TRIPS BY GAUGE • Log a trip with its time, a Too low, Good or Too high rating, and a note. • The nearest observation for that gauge and parameter within 60 minutes becomes the trip reading. Add a manual reading when needed; it is marked Entered by you. • Filter Trips by station, edit ratings and notes, or undo a deletion. • With at least 3 matching Good-rated trip readings, see your good-trip range on the chart and gauge. ▶ SET YOUR CROSSING • Set an alert for Crosses above, Crosses below or Enters your good-trip range. • Choose a threshold, Re-arm distance and station-local Quiet hours. • Alerts use standard notifications and periodic checks; battery saving can delay checks. ▶ FIND AND KEEP YOUR GAUGES • Search by river, station name or station ID in the US, England, Germany and France, and save gauges for later. • Choose Level or Flow and display m / ft or m³/s / cfs. • Map provides an outline overview with selectable station dots. • Export backup as a JSON manifest and numbered parts; restore needs the complete set. ▶ GOOD TO KNOW • Source availability varies. Missing readings or observations older than 3 hours show No recent data in the station detail. • Stage comparisons need matching reference metadata and are not available at every gauge. • A trip can have Reading unavailable. Your good-trip range is not a safety guide. This is not a warning service; check local authorities. • Location for Nearby stations is optional. Notifications need permission. • Backups are created in app storage before sharing; copies saved elsewhere stay where you put them.
