There are no fish in Southern Alberta. We are all lying & we only fish the Red Deer river just below Dixon Dam.
Just kidding Teck, if you wanna fish the Highwood, anywhere betwen Longview & Cat Creek is good. The Crow is good anywhere downsteam from E Hillcrest Bridge. Below the Lundbreck falls you will find there are Browns & Bulls (as well as everything else) but above the falls you can expect Rainbows & Rockies (*primarily*) I would suggest that if you fish the Crow & are not having much luck, move. I don't think that dries will be a way to spend much time at the moment. Call Vic at the Crowsnest Angler for more up-to-date info on the Crow, and most of all, have fun!
Good Luck!
