@ -31,6 +31,22 @@ Where {label} is:
flow_cfs segment is dropped when parameter_code is 00065 only (no
companion discharge reading). lat/lon segment is dropped when coords are
missing (rare since curated sites have coords).
Operational status (2026-06-08):
PARKED — Idaho USGS sites return discharge only (parameter_code=00060).
Gage height (00065) is not present in any retained CENTRAL_HYDRO envelope
(confirmed: 113-envelope JetStream replay, 0 stage readings). Without
00065, compute_threshold_state() always returns "normal", the
upward-crossing check never fires, and this handler broadcasts nothing.
The threshold/flood-stage machinery and IDAHO_CURATED_SITES thresholds
are correct and should be preserved. The adapter will become active if/when
USGS sites serving Idaho gage height data are added to the curated list.
Enrichment idea (parked same date): if NWS issues a flood warning (FFW/FLW)
and a NWIS gauge in the same county is above action stage, annotating the
NWS wire with the gauge reading was considered. Blocked by the same 00065
data gap — revisit if stage data becomes available.
