On the way to Moldova, I had to go upstream the Main and Main-donau canal to reach the Donau.
Over 70 locks I did pass. Sometimes with help from the lockmaster and the lock. Later on i had to take the kayak out on my wheels and walk around. This last is very tiresome.
The lock with most difference in waterlevel was Erlangen, Germany.
Over 20 meters.
Take a break
