Danube water levels

Below we list links to water level information along the Danube. As the Danube's water level is regulated by a system of locks along its way, floodings are rather rare. However, strong rain can lead to high water and even to regional floodings (as devastating as in 2013). These floodings occur every ten to fifty years now and can happen at any time throughout the season. Good news: Local authorities know the value of cycle tourism and rebuild the cycle paths shortly after. At least, detours get signposted.

Occasionally relevant for cyclists: High water levels after strong windstorm can lead to crossing ferries discontinuing their service, due to branches and wood in the stream. Ferrymen fear having their boats damaged. Keep that in mind when planning next day's route.

Droughts, as seen in 2018, only effect river cruises and barges as well as liner ships, not cyclists. River cruises might be forced to bus their passengers around the river sections with low water.
