how do i create a lake with world builder?

go into terrains then select coast then go to a tile where you want your lake and left click (make sure it has land round it) as you will see that tile is now a lake. click on tiles next to it to make it bigger

Worldbuilder calls it an ocean, but when you drop back into the game, it turns into a lake. If your lake is more than 10 squares large, it also ends up being an ocean.
