Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I use several baits(spawn/bags) for spring steelhead fishing and would like to tie my own flies. What are the materials/hook sizes needed? Thanks

You are asking for an awful lot of data and information for a first time poster. I'd suggect you Google "Flies needed for spring steelhead". Then when you get a few anwsers copy down the names of those flies and Google "fly pattern recipe for XXXXX" You fill in the name of the fly. I'd recommend Hares Ear, Prince, Pheasant Tail, Black stone fly al in sizes #12 - #16. Have fun.
