All these relkations exist for long years - no idea why someone divides one (not so big) lake into three.
These relations have to be combined.
Means that 900368 has the correct and closed outline = this is the one to persist.
All inners from 405902 and 900371 have to be moved to 900368.
Once done 405902 and 900371 have to be deleted.
Quite an effort but IMO there is no other way if this issue should be resolved.
The southern part of Maaninkajärvi and what is called here as Pohjois-Kallavesi belongs to the same lake of Kallavesi.
The correct borders of Kallavesi according to Järviwiki: https://www.jarviwiki.fi/wiki/Kallavesi_(yhd.)# (select from the map menu “vesistöalue”).
I could tackle that but since I’ve used so far only ID editor, the relations are sometimes giving me error messages that halts my work.
Someone (or someones editor) destroys relations in Finland:
See here:
Lake Haukivesi

2665335;2012;617;Mid part of Lake fragment
Together these fragments are Lake Haukivesi
Its always the same picture: A relation exists and while editing someone breaks it apart.
I have numerous Relations with same name in my Checklist, enough to keep someone busy for weeks.
And, even if repaired, this Relation is already covered by bigger Relation Saimaa.
There are a lot of other relations that covers the same area (=duplicates coverage) as Relation Saimaa
It should be noted that Saimaa as a whole consists of several smaller lakes and thus the relations for them are needed. Of course, broken relations should be corrected and obvious duplicates should be deleted.
