Pass Lake

Type: wet

Hook: #16 wet fly hook, standard or 1x long lightly weighted

Tail: Mallard flank, short

Note: Gool fly in the spring and early summer. Originated in Wisconsin by a minister in 1938. Fished early in my career, forgotten and resurrected. Use it for the time when the early gray/black caddis (#18) emerge. Dark nymphs like this (and the Prince) I beleive are taken as pupae. The shuck of the emerger is crystalline and I think this is why the white wing and mallar blank bay help. Fish dead drift with indicator or swing and twitch.
