Interesting you feel that way. Being very familiar with the area I would say that most traffic that picks up for fishing is smallmouth fishermen on the river in jet boats. I don't notice an uptick on trout streams. But, I do not spend enough time on this stream at any given point in the year and when I head back there to fish it's mostly just because I feel like it. I tend to fish it more in winter, however, and that was only the second time I've ever seen anyone back there fishing that wasn't right at the picnic area.
Generally I fish unstocked streams in February and March and never see a soul. Heck, I rarely see a soul after the season opens except for the first two weeks or so..
