I have a suggestion. Get closer to the headwaters and away from urban sprawl that creates the toxins that creates six legged frogs. The reason you hear some things about the Vermillion is that there are some trout in it, in fact, some very far and few larger trout, and the reason you hear about it is that the Twin Cities TU has taken an interest in the Vermillion.
With that said, the Vermillion is under no special regulations that would protect any possibility of sustaining any relevant population of trout, nor is it being overtly protected from the dangers of over-population.
Honestly, it has the potential to be something decent, but mankind will wipe out that potential before anything can be done.
I’d suggest either Hay Creek, western Wisconsin, or traveling to beautiful southeastern Minnesota if you want to catch some trout.
