With that said, issues with water boundaries "overflowing" can be an
indication of broken/incorrect OpenStreetMap (OSM) data for the river
edge at the spot where the overflow begins. So it is very possible
that these overflow spots indicate that some fixing of the master OSM
data is needed. However, properly fixing water booundaries in OSM is a
non trivial exercise, so if you don't feel up to doing so you may want
to contact a local OSM mapper to check the boundaries for issues and
fix those that are found.
Xavier, thanks for your feedback.
Agreed the "overflow" anomalies are most likely due to errors in the
water-boundaries on OSM.
Correcting them is a "foreign country" to me.
The true geometry of the land is visible for all to see on OSM
(OpenStreetMap).
Please could someone competent at editing OSM make the corrections? (They
could hardly make it worse!)
You might have better luck finding an OSM mapper local to that area on
one of the OSM mailing lists
(https://lists.openstreetmap.org/listinfo).
Suggestions:
1) Outdoor-natural
(https://lists.openstreetmap.org/listinfo/outdoor-natural)
or
2) The 'Talk-??' list most local to the geographical area where these
elements are mapped. I leave this selection to you to perform.
