Olt

Frequently asked questions

How long is the Olt and what basin does it drain?

615 km, from the Hășmaș Mountains, near Bălan, to the Danube, near Turnu Măgurele, with a basin of 24,050 km² and a mean discharge of 174 m³/s at its mouth. It is the longest river that flows entirely on Romanian territory, and the Olt level is read at a single gauge on the platform.

Which gauge does the Olt have and what does Hoghiz read?

Only one, at Hoghiz, with a single day of readings in 2026, so no records or long-term averages. On 25 October 2026 the gauge showed 48 cm, and without a longer series the figure is not compared with the monthly normal.

Which thresholds does the Olt have?

None: the Hoghiz gauge has no LDC, HDC or defence steps on the platform, so the page shows the level and its variation, not the comparison with low or high water.

Where does the Olt flow into the Danube?

Near Turnu Măgurele, after 615 km; there the Danube is measured at kilometre 597. In May 2014 the river rose at Turnu Măgurele to 634 cm, on 24 May.

How is the model forecast read on the Olt?

It does not exist: the Hoghiz gauge has no model forecast, and the platform does not fill gaps in the series with a model. The one-day series remains a gauge reading, not a computed value.
