Comment: The venerable Doc Spratley is a very effective pattern on the local pothole lakes. It was developed by Dick Prankard who named it in honor of dentist Dr. Don Spratley who lived in Mt Vermont Washington. It is a very popular BC lake fly. It mostly likely imitates the nymphs of small dragon flies and damsel flies.

Comment The variation I use is pretty skinny. It is intended to imitate small leeche sand damsel fly nymphs. It’s a simple pattern to tie, but quite effective. The only special part is the use of a bent hook.
