Fly Fishing Beaver River - Tushar Mountains

Overview

The Beaver River's Tushar Mountains reach is a steep canyon stream between the South Fork confluence and the Fishlake National Forest boundary. Boulder pockets, plunge pools and willow-lined banks favor short casts and careful approaches. Brown, rainbow and brook trout inhabit the canyon, where a light rod and a simple dry-dropper rig suit the closely spaced holding water.

The Canyon and Its Trout

Wild brown trout are the backbone of this fishery, and they are the reason to make the drive. They are canyon fish, typically 8 to 12 inches, thick through the shoulders and painted the deep butter-and-crimson of trout that live in cold, clear water over dark rock. They hold exactly where you would expect in a stream this steep: in the slack cushion at the head of a plunge pool, along the foam line where the pool tails out, and hard under the willow roots on the outside of every bend. Rainbow trout are stocked in the canyon and show up most reliably in the slower water near the campgrounds and pullouts where they are released; they are eager, fight well for their size and make a fine confidence builder on a slow morning. Brook trout fill out the cast, most often in the colder, faster water toward the top of the reach where the South Fork comes in and the creek runs at its highest elevation. A small attractor lets you cover the upper pockets without a long cast.

Fish size is honest here. A 12-inch brown is a good fish, a 14-inch brown is a story you will tell, and anything larger is a genuine surprise pulled from a pool deeper than it looks. Anglers who need a trophy to justify a day should look elsewhere. Anglers who measure a day by the number of pockets that gave up a fish, by the color of the trout and by the character of the canyon will find the Beaver's canyon reach hard to beat for the price of a short drive off Interstate 15.

Reading Small, Steep Water

The single most useful skill on this creek is knowing where the fish can actually hold. With nearly 170 feet of drop per mile, most of the current is moving too fast for a trout to sit in, so the fish are concentrated in a small fraction of the water: the eddy behind every boulder, the slick just upstream of a rock where the current stacks up, the deeper bowl below each ledge and the shaded slot beneath any undercut bank. A run that looks like white noise from the road resolves into a dozen distinct lies once you are standing in it, and each one deserves one or two good casts before you move on. Fishing upstream is the rule; approach each pocket from below, stay low and keep your profile off the skyline, because the water is clear enough that a careless step will empty a pool before you make a cast.

Long drifts are almost impossible and mostly unnecessary. A three- or four-weight rod in the seven-and-a-half to eight-and-a-half-foot range keeps the fly under the overhanging cottonwood limbs, and a leader of seven to nine feet turns over a bushy dry fly with a beadhead dropper without piling up. High-stick the rig through the pockets with as little line on the water as possible, and set on anything that pauses the dry. Round, slick cobble and strong current make footing a consideration in the faster stretches. Willows crowd the banks in the lower canyon, so a roll cast and a bow-and-arrow cast will get you into water that a full overhead cast cannot reach.

Hatches and Flies

Bug life on the Beaver is typical of a Utah mountain freestone, and the trout are not selective about imitations. Caddis are the workhorse insect from late spring through fall, with evening activity that can turn a quiet tail-out into a scattering of rises just before dark. Small golden stoneflies and yellow sallies crawl out along the rocks through summer, and pale morning duns give the mayfly fishing its brief moment during the same stretch. Blue-winged olives cover the shoulder seasons in spring and again in fall, usually on the overcast afternoons, and midges are the whole story in the cold months when the fish are tucked into the deepest pools. Late summer brings the terrestrial game, and hoppers, ants and beetles tumbling off the streamside grass along SR-153 produce some of the most visual fishing of the year.

The box that works here is a simple one. Attractor dries in sizes 12 through 16 carry most days: Stimulators, Elk Hair Caddis, Parachute Adams, Royal Wulffs and Humpies will all draw looks in the pockets. Hang a Hare's Ear, Pheasant Tail or small Prince Nymph a foot or two beneath the dry and you have covered the surface and the water column in a single rig that fishes every lie in the canyon. Bring a few terrestrials for the late-summer grass, a handful of small olives and midge emergers for the cool-weather afternoons, and a couple of small streamers for the deeper plunge pools in fall when the browns turn territorial. Guides who fish this water will tell you that presentation and stealth matter far more than pattern, and on a creek this small they are right.

Flows and Timing

Snowmelt from the Tushar Mountains can make the creek fast and discolored in spring. As the melt recedes, clearer water makes individual pockets easier to read. In low water, approach pools quietly and keep unnecessary movement away from the fish. Snow and ice can complicate a winter visit to the canyon.

Summer lends itself to dry-dropper fishing in the pockets, while autumn's clear water rewards smaller flies and careful presentations. Choose a lie and adjust the drift to its depth and current rather than trying to cover the entire channel.

Access

Little Cottonwood Campground, off SR-153 east of Beaver, has an accessible fishing path along the river. Use the campground's designated parking associated with your campsite or visit; parking space is limited and campsites are reservable.

Nearby Water

The Beaver's canyon reach is a natural anchor for a few days in south-central Utah, because several of the state's quieter trout streams sit within a modest drive over the Tushars or down the interstate. The Sevier River below Piute Reservoir lies on the far side of the mountains and offers larger, slower water and heavier browns when you want a change from picking pockets. Just downstream of that, the Sevier's run through Kingston Canyon is another canyon fishery with more room to cast and a different feel entirely. To the south, Mammoth Creek through Hatch Valley trades the tumbling canyon for meadow bends and undercut banks, and it makes a fine second day on the way toward Bryce Canyon country. The three together let an angler based in Beaver or Panguitch match the day's flows and mood to the water rather than forcing a trip on a creek that is not ready.

The canyon rewards anglers who enjoy taking a small stream apart pocket by pocket. Keep casts short, work the sheltered edges of the current and leave room to adjust as the water changes.
