Benny,
When I see shucks like that and fish working on top, you should be able to take them with an emerger or cripple, or a shallow indicator rig. I don't have much success with deep indicator rigs (say 8+ feet). I miss too many takes and have to use lead, which means a bigger bobber.
I've had better succuss with a wieghted nymph, say copper john, and a midge pupa trailer 2 feet behind it. I use flouro leader and tippet, on a full intermediate line. What I get is a straight line connection to my flies and better feel for the takes. I'll count down the depth until I start getting bit, using a slow hand-twist retrieve. Depending on how long and fine my leader, I can get down to 20 feet or so. Any deeper, there'd be too much line deflection(belly). Oh, be ready for a take as you start stripping in for your next cast. There's something about a midge slowly ascending that gets their attention.
Good luck.
