I'm using this website to monitor the levels at Bratislava and Budapest:

I just don't know what to view as a minimum level for the boat at any of the locations. Good for observing a trend, however.
We are arriving in Munich a day early as well. I hope it goes as planned and we can toast our good fortune.
