Ya I'm not sure what they were eating...I had a limited selection of flies in my "lunchtime at work emergency fly fishing kit" - had my money on streamers and a couple dries as backup. Nothing visible on the surface or in the air except for snowflakes, some of them did a small splash (you could hear them good) and a few did a slowish head, back and tail rise. Got a good view of some of them and they were good size trout - not small splashy ones, although it sounded like that at times. Seen a definite larger rainbow and a smaller brown (yellowish telltale markings). That's the other question I guess - is that common to have rainbows and browns feeding in the same seam? Hindsight is 20-20 but maybe I should have tried a dry with a trailing emerger or a nymph then. Are there any backswimmers in the Bow downtown/above the weir? I find the Bow downtown less silty and the rocks seem cleaner compared to the lower sections past the wastewater treatment plants. And hey - I wouldn't feel dirty if I were you! - nothing wrong with catching fish like that!
