Springs

[Sami]

Yes, it's springtime! (pun intended)
We'll be adding springs, water sources bringing groundwater to the surface, in the terrain generation. Springs can be found at varying environments on zoomed-in maps.
A spring found in the wilderness may provide a great spot for a homestead for those who like to live further away from the lakes or rivers. And moreover, springs remain unfrozen even in the winter.
   Some time ago there was also a suggestion to have village water supplies to remain unfrozen for easier spotting. Now we'll make it so the village water supply ponds will be actually springs from now on. And for the migrated characters, the existing village ponds will be turned into springs as you visit these villages.

I guess will also take a little browsing of the old Finnish spellbooks to see if there are inspiring magical means or remarks related to springs. Springs were traditional places of mystical powers and certain guardian spirits. New spells or quests potential is high.

These are future features - not yet functional in current version 3.83.

That’s a great addition to have.

Will you work on adding brooks and creeks from those springs also?

No, just springs for now.
Brooks and creeks would be a great terrain feature, but that requires kind of a world generator overhaul to have them find meaningful pathways into the larger bodies of water.
