Upper Fremont River - UT

The Upper Fremont River, flowing from Fish Lake to Johnson Valley Reservoir, offers a classic high-country trout fishery in south-central Utah. Cold, clear water supports wild brown and stocked rainbow trout, with average sizes between 10–16 inches.

Fly anglers favor this stretch for its consistent nymphing and summer dry fly opportunities. Productive patterns include pheasant tails, hare’s ears, and caddisflies. Streamers work well in deeper runs. Spin anglers use small spinners and jigs to target larger pools and undercut banks.

Access is easy via Forest Road 640, and most of the river runs through public land. Primitive camping is available nearby, and Fish Lake’s facilities are just minutes away. Fishing is best in spring, summer, and fall, with winter midge hatches providing occasional cold-season action.

Regulations follow Utah’s general fishing rules with a four-trout daily limit. Anglers should consult the Utah Fishing Guidebook for any updates or special regulations.

The Upper Fremont River delivers scenic walk-and-wade fishing with wild trout and minimal pressure, making it an ideal destination for both new and seasoned anglers.
