Oryahovo gauge — Danube water levels
Free-flowing The river runs free here, so the level is the constraint: this is where a drought actually binds a hull.
Mid-border-run gauge opposite the Romanian bank; the lowest published low-water reference on the Bulgarian stretch, level with Ruse's.

ИАППД — official Bulgarian Danube forecast, six days (Bulgarian)
The authority's own forward table for Oryahovo, Nikopol, Svishtov, Ruse and Silistra, giving a maximum, a forecast and a minimum for each of about six days. It is the only forward product published for this stretch: BfG forecasts German federal waterways and reaches nothing here, and EuRIS publishes no prediction series for these stations.
Waterlogged does not reproduce or interpret the values on this page. Nothing from this page is copied onto ours. The forecast is the authority's and is shown as theirs, on their site.

ИАППД — official Bulgarian Danube water levels (Bulgarian)
The Bulgarian Danube authority's own level page: level, discharge, the change over the last twenty-four hours and water temperature, for twenty stations along the Bulgarian bank. Eight of the twenty are read by hand and twelve report automatically, and it is the source of the readings this site shows for this stretch.
Waterlogged does not reproduce or interpret the values on this page. Not link-only. ИАППД publishes reuse terms whose one operative condition is that it be named, visibly, as the source of the primary data, and this site names it beside every reading. The link is here so a reader can reach the authority's own page, not because we may not quote it.

EuRIS — European River Information Services portal
The European portal that distributes the current Budapest, Kienstock and Bulgarian lower-Danube readings Waterlogged shows, naming OVF, viadonau and ИАППД as the originators.

Source, licence and limits
- Source: EuRIS Hydrometeo v3 — terms of use.
- Measurement time: every reading on this page shows the time it was taken, and a stale reading is flagged rather than reused.
- Transformation: the level is the publisher's. The gap, where one is shown, is Waterlogged's arithmetic and is labelled as such.
- Reference-data note: live level via EuRIS (originator IAPPD); low-water reference LDC transcribed from IAPPD's own RIS Index of 1 July 2021 and confirmed identical in the EuRIS thresholdReference for this series on 14 August 2026. See waterlogged/refdata/lower_danube_stations.json.
- Not for navigation. Nothing on this page should be used to plan the movement of a vessel.
Bulgarian lower-Danube station, originated by IAPPD and delivered through the EuRIS Hydrometeo v3 API. Carries the Danube Commission's published low navigable water level and no depth model: the reading and the reference line are real, the ship-need arithmetic is not attempted.
