OK, thanks for the reply.
So, maybe you might want to remove the "dyke" tag if it’s not there.
Feel free to add the extra details you spotted there, it is interesting to have them on the map.  Flanders refreshes aerial imagery about once a year for each area, so probably in a few months there will be newer images that will make it easier to trace the water basin and spot the new objects.
For clarity, no-one is saying you should stop mapping at all, we merely requested to improve how you describe your work.
Have a nice day.
