Fished it for a few hours yesterday. A few rainbows and browns, some of them looked to be holdovers from last year. Flow was pretty normal, didn't get a water temp. All fish were taken on a white zoo cougar.
Yeah, I've caught wild ones, noone near the DHALO though. The DHALO stretch pretty much has 1, maybe 2 good runs where all of the trout are and that's where everyone fishes.
There are wild fish there, but probably only 9 months of the year, it gets pretty warm most years, last year being one of those years. I doubt you caught any holdovers there, unless it was stocked during the fall.
