We recommend fishing the deep part of the Clarks Fork canyon after mid July for safety reasons. By mid-July access and fishing will be much better than early July. Access into the canyon of the Clarks Fork requires a good heart, stout body, excellent wading skills, bear and mosquito repellent. Dries – royal trudes, royal Wullfs, stimulators, humpies, elk hair caddis, parachute Adams and Ho Candies for dries. Nymphs would be Pat’s rubber legs, black or tan North Fork Specials, Halfbacks, Prince nymphs, bloody Mary’s, and Bloom’s optic nerve. Sizes 8-14.
