With the exception of the wild trout pops in a number of the stocked trout streams, pretty much all the "listed" wild trout waters in Crawford County are in one of the following categories: 1) Posted up tight and they mean it (about half..) 2) ostensibly posted, but access *may* be possible with permission and a gentle approach to the landowner (about a third..) 3) The balance are a grab bag: too small or alder-clogged to be enjoyable or even fished, other than to prove a point. Some of these are not posted and see a few bait guys each year and a few of them have short sections of less brushy water away from the bridges where fishing is possible. But even on these streams, it is probably best to always ask permission.
Actually, probably the best wild trout fishing in Crawford County from an assured access point is in the upper halves of some of the stocked streams.
