River conditions

Every report Waterlogged River Cruise Watch produces rests on these feeds. When one of them falls behind its freshness target, archive verification fails, or one required station is missing, the affected assessment is withdrawn. A healthy station on the same feed cannot mask the failure.

Where the monitored water is low

This river-system view makes the latest accepted readings easier to place. It is schematic, not geographic: station order follows each river, while spacing and river shape are not to scale.

Schematic gauge context — not a navigation chart. Where a depth model exists, colours apply the latest accepted observation to a 1.60 m reference draught plus 0.20 m clearance. Budapest and Dresden use labelled judgment bands; context-only gauges remain neutral. These states do not forecast a sailing or report operator action.

workable for reference vessel limited margin below reference threshold context only unknown or withheld

“Workable” is a current-state model result for the stated reference vessel, not a declaration that every ship can pass. Budapest and Dresden use Waterlogged judgment bands; Maxau and Kienstock are low-water context only. High-water rules remain separate.

Kaub Rhine · KAUB	23 cm	Low	Reference-depth model	07 Aug 2026, 04:45 CEST	55 cm below the level that keeps 1.90 m in the fairway. PEGELONLINE (WSV).
Maxau Rhine · MAXAU	321 cm	Context only	Context only	07 Aug 2026, 04:45 CEST	This location is shown for river context. Its low stage does not create a low-water route call in the current model. PEGELONLINE (WSV).
Cologne Rhine · KOELN	60 cm	Low	Reference-depth model	07 Aug 2026, 04:45 CEST	79 cm below the level that keeps 2.50 m in the fairway. PEGELONLINE (WSV).

Hofkirchen Danube · HOFKIRCHEN	151 cm	Low	Reference-depth model	07 Aug 2026, 04:45 CEST	56 cm below the level that keeps 2.00 m in the fairway. PEGELONLINE (WSV).
Dresden Elbe · DRESDEN	53 cm	Low	Waterlogged judgment bands	07 Aug 2026, 04:45 CEST	37 cm below the 90 cm level where sailings on this stretch are usually disrupted. That band is our judgment, not a measured depth. PEGELONLINE (WSV).
Schöna Elbe · SCHOENA	66 cm	Context only	Context only	07 Aug 2026, 04:15 CEST	This location is shown for river context. Its low stage does not create a low-water route call in the current model. PEGELONLINE (WSV).
Trier Moselle · TRIER	222 cm	Context only	Context only	07 Aug 2026, 04:45 CEST	This location is shown for river context. Its low stage does not create a low-water route call in the current model. PEGELONLINE (WSV).
Cochem Moselle · COCHEM	215 cm	Context only	Context only	07 Aug 2026, 04:45 CEST	This location is shown for river context. Its low stage does not create a low-water route call in the current model. PEGELONLINE (WSV).
Budapest Danube · BUDAPEST	24 cm	Low	Waterlogged judgment bands	07 Aug 2026, 04:00 CEST	76 cm below the 100 cm level where sailings on this stretch are usually disrupted. That band is our judgment, not a measured depth. EuRIS Hydrometeo v3.
Kienstock Danube · KIENSTOCK	152 cm	Context only	Context only	07 Aug 2026, 04:45 CEST	This location is shown for river context. Its low stage does not create a low-water route call in the current model. EuRIS Hydrometeo v3.

Feeds

Feed freshness against each feed's maximum age target
Feed	Last success	Age	Target	State	Detail
`pegelonline`	07 Aug 2026, 04:57 CEST	just now	45 minutes	fresh	last success 1 min ago (within the 45 min SLA)

Per-gauge acquisition and storage health

A gauge is fresh only when its own observation is current and its raw source response has a verified archive receipt. Feed-wide green status is not enough.

Which parts of this build are real

Waterlogged River Cruise Watch is assembled from four independent parts. This table says, honestly, which of them are wired to live data right now and which are running on built-in demonstration content.
