Danube water level alerts: flood (HDC) and drought / low water (LDC)

DanubeAlert helps you monitor Danube water levels and understand when a station crosses a flood threshold (HDC) or a low-water threshold (LDC). This page summarizes historical alert episodes across Danube countries and key canals/branches.

If you search for Danube water level today, Danube flood warning, low water levels on the Danube, or Danube drought alerts, this overview is designed to answer those questions with clear episodes, durations, and exact levels.

Use Flood Alerts (HDC) for high-water episodes and Drought Alerts (LDC) for low-water episodes. Filter by country to focus on the stations you care about: Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Romania.

Each episode is computed from station thresholds and the daily first reading. Short data gaps can be bridged up to 3 days so episodes are not split due to missing data. Episodes are updated twice per day.

For each alert episode you can open “View levels” to see the exact daily levels during the episode. This is useful for planning, safety awareness, and understanding seasonal patterns on the Danube.
