Rivers

[JimMorrison]

Do you mean it increases the average population? I've never noticed them (and in some regions there can be a lot of Fresh Water provinces on my maps) having anomalously high incomes.

I'd assume it's the same for Grassland, there is no actual income modifier, they just tend towards greater populations.

No, there's a real difference in income. I think I've seen the actual numbers somewhere, and I think I remember that it was +20% or so for rivers.

I have searched a little and found only "fuzzy" answers:
