OPEN — melt essentially done (trail reports 6/21–6/23: only scattered mud spots and occasional snow drifts up high) · Camp Dick / Peaceful Valley reaches fishable · upper Indian Peaks basins cold but accessible · wild small fish on dries

Strategy

OPENED — melt essentially done and trail reports (6/21–6/23) show only scattered mud and occasional high drifts. Camp Dick + Peaceful Valley CG areas accessible via Hwy 72; fish the meadow and pocket water upstream of Camp Dick. Eager wild brook/brown/cutthroat on attractor dries — 8.5-ft 4-wt is the right rod for narrow brushy water. RMA 6/20: St. Vrain system a touch high with warm-ish temps — mornings best. Expect mosquitoes.

Detailed report

STATUS CHANGED from High-Country Closed to Fair / Picky: melt essentially done (~2–3 weeks ahead this year); late-June trail reports show only scattered mud spots and occasional snow drifts at the highest elevations. Camp Dick / Peaceful Valley reaches fishable now. Beautiful small water, bountiful access; big fish rare — wild small fish dominant on attractor dries. Mountain pattern: today (Sun Jul 5) ~77°F, mostly sunny — all-day window; scattered storms return Tue–Wed. No dated public fly-shop report for this creek — status is a staff synthesis of trail and St. Vrain system flow reports.
