So I went and fished the Ogden Canyon section yesterday morning. Saturday was sorta warm, so I thought the water temperature might be a little warmer come Sunday and the fish might be more active. But I didn't catch anything: the fish weren't eating anything I tossed out there.
I did see a bunch of them splashing around sporadically, so I think the spawn might still be going on. I got some attention when I tried an olive streamer, but none of them ever chased all the way to a strike.
I also saw the biggest fish I've ever seen in the Ogden river. He was a minimum of 24" long, but I think it was closer to 28". I had no idea they could get that big in the little Ogden river. Pretty neat! I was tying on the streamer at that moment, and he moved on before I could get a shot at him.
