Latest Gauge Readings

Provisional gauges use a 999.0 ft flood-stage placeholder (see docs/gauge_flood_stage_notes.md). Flood-stage % is not used for readiness; rate-of-rise is suppressed when observation gaps exceed the configured max gap (H-02 / H-03).

Scheduler pace (auto Fast / Normal)

Scheduler Auto cadence

Pace Normal

Auto-managed · Normal (USGS Nones · NOAA Nones)

Policy: weather alerts within 100 mi → Fast; gauges falling / near normal after weather clears → Normal (active weather trumps falling gauges). No manual toggles.

Normal Mode is appropriate based on current available information.

Context notes
  • Clear/current operating picture: no current alerts, no concerning gauge correlation, and no rising river trend.
