Proposed features/Intermittent Lake
From OpenStreetMap Wiki
|Definition:||Largest boundary of a lake that seasonally or occasionally disappears or drastically changes size|
|Rendered as:||Blue hatching|
The largest boundary the lake normally reaches would be tagged with this tag. The smallest would be tagged as lake or river, as appropriate. Probably as river Stržen in the case of Lake Cerknica.
