Near Kremmling, the upper Colorado River is a freestone fishery that offers plentiful trout fly fishing. You can expect to find both rainbow trout and brown trout around 15 inches in length.
One of the best sections is from Granby near the Fraser River confluence downstream to Kremmling. Many fishermen will start at Hot Sulpher Springs and work up or downstream depending upon the hatch conditions. There are many nice riffles, pools and runs. The river averages between 40 to 80 feet wide in this area and is ideal for wading.
Downstream of Kremmling as the river heads southwest/west, the Colorado River picks up spead and widens as more tributaries enter. Many fly fishermen float the stretches below Kremmling, but you may want a guide since there are several Class 3, 4 and 5 sections. Also, river access can be more tricky and infrequent. The State Bridge and Pumphouse areas are popular with fly fisherman.
The caddis hatch is from May through September.
