Impressive progress, keep it up :)

I've played this game in Mayo tonight, although I altered the query to
select even named lakes so that I could add the water=* tag. While at
it, there's a lot of lakes created with scanaerial that can do with
manual fixing.

I prefer to use the josm "todo" plugin, because it pans, zooms, and
selects for you with just one click :
1) Use JOSM search (I just searched for "type:relation" because that's
what I limited my overpass query to)
2) Click "add" in the todo side-panel to populate the todo list
3) Click "zoom" for the first item
4) Edit the object
5) Click "mark"
6) Repeat.steps 4-5 until done or bored.
