Colorado's trout waters flow from the Continental Divide through alpine meadows, canyons, and valleys. The state's high elevation provides cold, clean water ideal for trout. Major river systems include the Colorado, South Platte, Arkansas, and Rio Grande.
Best Times to Fish in Colorado
Spring (March-May)
Spring runoff typically peaks in May-June, affecting many rivers. Tailwaters fish well during runoff. Look for BWO hatches on cloudy days. Focus on lower elevation waters as they clear first.
Summer (June-August)
Summer is prime time for Colorado fly fishing. Caddis and mayfly hatches are prolific. High country streams and lakes are accessible. Early morning and evening offer the best dry fly action.
Fall (September-November)
Fall brings spectacular fishing as browns prepare to spawn. Kokanee salmon runs draw big trout to tributaries. Streamer fishing is highly effective. Colors peak in late September.
Winter (December-February)
Winter fishing is productive on tailwaters like the South Platte, Frying Pan, and Blue River. Midge hatches occur daily. Fish the warmest part of the day. Small flies and light tippet are essential.
