Not sure what you are fishing for? but I only fished it once dont know alot about it. but since your a member of this site ill tell you a little tick I would use. in the search bar on this site type in -rough river- or maybe even -rough river fork- look through thouse post and if you want info on march time look at the dates you can find some very good post like these.
