River-gauge records and station access along the Bhote Koshi–Trishuli–Narayani corridor, 25–31 August 2026 — Nepal DHM | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: Official river-map station pages and historical gauge-level query routes along the Nepal-side cascade corridor and tributaries. Velocity, rainfall and unresolved station entries are distinguished from stage observations.
Review findings: Automated source screening and metadata/technical assessment. Resource eligibility, independent human screening and manuscript inclusion remain unassigned. No component-specific open redistribution licence was established. Public access is separate from permission to republish observations or document contents. This catalogue publishes metadata and source links only.

Inspect edge truncation, internal gaps and quality flags before event reconstruction. Observed cadence is not a guaranteed sampling schedule.
Reconcile CHWRR report labels/indices with the live catalogue: report Rasuwagadhi 446.42 versus live 446.22, and a Syabrubesi-labelled 08:40 last observation with Rasuwagadhi-like thresholds. Do not merge station evidence by name alone.

The native query returned 162 readings; 162 fall inside the strict UTC event window. Counts retain all returned rows; none were removed during this assessment. Raw timestamps are interpreted using their supplied offsets. Current map status and warning labels are not historical event observations. Water level is reported in metres against a source reference that is not established as a common elevation datum. It is not flood depth or discharge. Telemetry ending does not by itself identify flood arrival, and an available-record maximum is not necessarily the event peak.

Host / aggregator: dhm.gov.np
Relationship to record: The native query returned 163 readings; 163 fall inside the strict UTC event window. Counts retain all returned rows; none were removed during this assessment. Raw timestamps are interpreted using their supplied offsets. Current map status and warning labels are not historical event observations. Water level is reported in metres against a source reference that is not established as a common elevation datum. It is not flood depth or discharge. Telemetry ending does not by itself identify flood arrival, and an available-record maximum is not necessarily the event peak.

The page exposed no current station metadata. Raw timestamps are interpreted using their supplied offsets. Current map status and warning labels are not historical event observations. Water level is reported in metres against a source reference that is not established as a common elevation datum. It is not flood depth or discharge. Telemetry ending does not by itself identify flood arrival, and an available-record maximum is not necessarily the event peak.

The native query returned 1,006 readings; 1,006 fall inside the strict UTC event window. Counts retain all returned rows; none were removed during this assessment. Raw timestamps are interpreted using their supplied offsets. Current map status and warning labels are not historical event observations. Water level is reported in metres against a source reference that is not established as a common elevation datum. It is not flood depth or discharge. Telemetry ending does not by itself identify flood arrival, and an available-record maximum is not necessarily the event peak.

Current map status and warning labels are not historical event observations. Water level is reported in metres against a source reference that is not established as a common elevation datum. It is not flood depth or discharge. Telemetry ending does not by itself identify flood arrival, and an available-record maximum is not necessarily the event peak.
