Luckily, I've found a couple small streams that support them. Interestingly, I've found that the Driftless brook trout are much paler than those in the East. I think this is likely a result of the light-colored stream bottoms common here, but it could also be a genetic difference.
Below are a couple pics of fish I caught last weekend on one of the nearby brook trout streams. Both fish hit streamers. These fish will hit dries, but I find it easier to present a streamer with a downstream presentation.
