no you are wrong if you obtain minnows from area b which were harvested from area b. you may may use the minnows from Riverton, as long as you use them in the established area according to the drainage systems in the regulations. for example if I purchase them in Riverton from a licensed dealer who got them from the windriver or bighorn drainage, then I can use them say at wardell/Harrington. I was concerned about this at first so I called the game and fish and confirmed what I just stated. but on a another note I ended up just buying the minnows at marvins minnows in Worland what a great guy I highly suggest going through this nice sportmans.
