Heading to Montana on the 3rd of July in Fly Fishing Posted July 19, 2015 · Report reply You'll never hear a complaint about the fish from me and it was an amazing learning experience also. I stepped up my fishing a bit learned some good stuff from some other fantastic fishermen from the US and Canada and set my self up for a job in the industry (hopefully). How ever. I am dying now that I am home. My home river is 78 degrees in the afternoon right now and 72 in the dawn hours and is fishing like a drainage ditch what ever trout are hanging around have to be slowly dying so fishing for them is totally uncool. The water in the Big Horn was in the 50's the whole time I was there with 85+ afternoon air temperatures. All dams should be bottom release. Thankfully on 1 August I will be moving to a new place right across the street from one of the best trout streams in the state and just up stream from one of the best stretches of that river.
