River
Sava
The Sava crosses Slovenia, Croatia, Bosnia and Herzegovina, and Serbia and has 40 stations on DanubeAlert; 3 of the gauges have an official forecast. · Slovenia, Croatia, Bosnia and Herzegovina, Serbia
The Sava has 40 stations on DanubeAlert, spread across Slovenia, Croatia, Bosnia and Herzegovina, and Serbia. At Zagreb, the station with the longest series (since 1900), the level ranged from -336 cm (1993-08-23) to 499 cm (1964-10-26). Low water is most frequent in August, when 19% of station-days fall below the low-water level (LDC). High water above HDC occurs mostly in April (10% of station-days). In the irrigation season (April–September), 7% of station-days were below LDC.

Frequently asked questions
- What does today's water level mean?
- Stations with reference levels: 5 · below LDC: 2 · above HDC: 0 · updated: 5 November 2026.
- How many gauges does the Sava have?
- The Sava water level is read at 40 gauges with daily readings: 24 in Croatia, 7 in Slovenia, 5 in Serbia and 4 in Bosnia and Herzegovina. They cover 587 km, from kilometre 0.97, at the Danube mouth, to kilometre 588.
- What are the Sava's extremes?
- The series records are 1,155 cm at Gunja, on 17 May 2014, 853 cm at the Sremska Mitrovica gauge, on the same day, 738 cm at the Sava level at Belgrade, on 16 April 2006, and 499 cm at the Zagreb gauge, on 26 October 1964. The lows fell to 121 cm at Belgrade, on 15 September 2026, to -18 cm at Sremska Mitrovica, on 13 September, and to -336 cm at Zagreb, on 23 August 1993.
- Which official thresholds does the Sava have?
- At Belgrade the navigation thresholds are LDC 162 and HDC 560 cm, and the defence steps 500 cm, regular defence, and 600 cm, extraordinary. On 27 October 2026 the level was 132 cm, below all of them. The other Sava gauges have no LDC on the platform.
- How navigable is the Sava?
- The Sava is navigable for 587 km, from Belgrade to Sisak, on class IV. At Sisak, where the Kupa joins, the section for large vessels ends.
- How is the Copernicus model series read on the Sava?
- The Copernicus model series, GloFAS and EFAS, is computed discharge in cubic metres per second, not a gauge reading, so it is not compared with centimetres. It is read next to the measured discharge, which exists at 9 of the 40 gauges, and it has its own uncertainty and horizon. The model is not a flood warning.
- Why does Belgrade have two gauges?
- Because the platform's gauge stands on the Sava, at kilometre 0.97, with zero at 68.28 m, while the Danube is measured at Zemun, at kilometre 1,173. The figures of the two gauges are not mixed, even though the city lies at the confluence.
