This is the best summary I could come up with:

HAMBURG, Aug 2 (Reuters) - Heavy rain has raised water on the river Rhine in Germany to levels allowing cargo vessels to sail fully loaded, data from German inland waterways agency WSA said on Wednesday.

Data from the WSA’s website Pegelonline showed that the last shallow sectors of the river around Cologne had now reached levels generally permitting full vessel loads.

Water at the chokepoint of Kaub had risen sharply allowing sailings with normal loads earlier this week.

“You cannot rule out low water problems again if the summer turns dry but I would not expect serious difficulties for the next few weeks,” one commodity trader said.

German companies faced supply bottlenecks and production problems in the summer of 2022 after a drought and heat wave led to unusually low water levels on the Rhine.
