Boulder Creek (Boulder Canyon)
Seasonal notes
Boulder Creek near Orodell sits at the upper end of Boulder Canyon, about four miles west of town, where the creek is still a true mountain freestone rather than the urban corridor it becomes further downstream. Wild brown trout are the primary resident, with fish growing slowly in the cold, moderately fertile water. Runoff here peaks later than metro streams — expect blown conditions from late April through mid-June in most years, with the best dry-fly fishing in July through September. Blue-winged olives come off on cloudy afternoons from early spring through fall; caddis are a close second in June and July. The canyon is steep-walled and the creek is boulder-choked, so short-rod, high-stick nymphing and careful roll-casts are the standard technique. Orodell itself is a cluster of houses near a Forest Service trailhead — park there and fish upstream or down.
