I assume that "small" or "large" flags only affect province population/income/supplies, and not magic sites or its frequency, right?

I also assume that freshwater is invisible modifier (but you can guess it by presebse of the river in province, if map has been created correctly), which dioesn't affect site frequency but that enables some additional water sites, according to Zen. ( in addition to increasiang income in provinces with rivers and having possibilty of floods in random events). Is it correct?
