In regards to finding dollies, you really don't see them showing much until March and even then all you really see is fry boiling from being chased by these predators. Dollies do quite a bit of searching for food and will travel a fair distance within a day to attain it and so walking to find them is a good idea or better yet a pontoon boat. The Fraser is a great place for dollies, especially creek/river mouths where food gets flushed into the Fraser. Do not let the big water intimidate you on your quest for these fish. By the way Fishfreak those are some nice flies, good luck this weekend, Winter Steel.
