How to fish it
Fish Blacksmith Fork like a special-regulation canyon trout river where legal access and stable cold flow matter more than forcing extra miles.
Blacksmith Fork is most useful to anglers when RiverReports and USGS 10113500 show a stable, readable canyon flow and you are prepared to keep the day inside clearly public water and right-of-way entries. This is not a river for loose private-land assumptions. It is a Blue Ribbon-style trout plan that rewards short, careful wading, close attention to Utah's special rules, and a willingness to walk away when runoff, color, or crowding make the canyon feel small.
- Utah's 2026 Fishing Guidebook lists the Blacksmith Fork River from the first SR-101 highway bridge at the canyon mouth to the headwaters as closed from April 15 until 6 a.m. on the second Saturday of July.
- That same Utah guidebook says the canyon section is catch-and-release only with artificial flies and lures during the early and late open windows, allows only one trout over 15 inches, and carries a bonus limit of four brown trout within an eight-trout total.
- Utah DWR's Hardware Wildlife Management Area says licensed anglers can fish nearly 15 miles of streams and rivers on the WMA and can expect several trout species in the corridor.
- Utah DWR's stream-access guidance says anglers may float over private property, fish on public property where the managing agency allows it, and fish private property only when it is not closed to trespass or when the landowner grants permission.
Why the score looks this way
Public alertLowers score
An active alert is in effect: Red Flag Warning issued August 2 at 12:28PM MDT until August 2 at 10:00PM MDT by NWS Salt Lake City UT. Check public safety sources before going.
FlowUse caution
USGS shows 51 cfs with a stable over about 6 hours trend. Today's flow is unusually low for this date and below the usual low-water marker near 52 cfs. Low water can make fish spooky, warm, pressured, or concentrated; check temperature and handling risk.
HeatUse caution
The NWS forecast is near 86F. Fish early and verify water temperature where trout stress is possible.
SeasonHelps score
Summer opener through early fall: The main Blacksmith Fork window after the seasonal closure lifts and the river settles into cold pocket-water trout fishing.
Fishing usefulnessHelps score
Skip it during the seasonal closure, on any muddy runoff pulse, when late-season heat leaves the river thin, or when legal access feels uncertain.
Read the water
What changes the plan.
The strongest Blacksmith Fork days come after runoff has settled into a clear cold summer or fall shape, when the canyon has enough push to define seams without turning every crossing or bank slot pushy. If the river is rising, carrying color, or running so low that fish stack into obvious small pockets, shorten the day or move to a larger Utah option.
Clear stable midsummer flow
Best for short wading sessions, dry-dropper rigs, and methodical pocket-water coverage through the canyon bends.
Post-runoff drop
Often the best seasonal window once the river falls into shape and the wading picture becomes readable again.
Very low late-season flow
Fish smaller water carefully, lengthen leaders, and leave if the river looks warm, crowded, or too compressed to support a good trout day.
Runoff, color, or fast rise
A skip signal because the canyon gets smaller fast when current pushes against cut banks and slick rock edges.
Your trip plan
Know when to go—and when to skip it.
Best flows
Best once runoff drops into a clear, stable coldwater shape where pocket seams hold fish and crossings still feel controlled.
When to skip
Skip it during the seasonal closure, on any muddy runoff pulse, when late-season heat leaves the river thin, or when legal access feels uncertain.
Local plan
Base out of Hyrum or Logan, check 10113500 first, choose one section around the Hardware WMA or a clearly legal canyon entry, and fish it thoroughly instead of leapfrogging all day.
Backup water
Shift to the Weber River if you want a broader completed Utah option, or keep Logan River in mind once that page is built out for the site.
Hatches & flies

TimingWhat to watchUseful flies
Summer openerCaddis, attractor dry windows, and mixed nymph activityElk hair caddis, stimulator, pheasant tail, hare's ear
Fly pattern · report suggests “Elk hair caddis”Elk Hair CaddisLook for a tented elk- or deer-hair wing, clipped hair head, dubbed body, rib, and hackle palmered along the body. The body color should be labeled because tiers often match different natural caddis colors.See photos & how to fish it ↗
Fly pattern · report suggests “stimulator”StimulatorLook for a hair tail, dubbed abdomen with palmered hackle, tented hair wing, contrasting front hackle, and bright thorax or head. Colors and sizes vary widely and must remain labeled.See photos & how to fish it ↗+ 2 more reviewed guides in the Fly Box Mid to late summerPMDs, caddis, terrestrialsPMD dry, tan caddis pupa, ant, beetle, perdigon

Fly family · report suggests “tan caddis pupa”Caddis Pupa PatternsCaddis pupa is a life-stage family. Curved bodies, wing pads, legs, beads, and soft-hackle collars differ among exact patterns and must be labeled.See family guide ↗+ 3 more reviewed guides in the Fly Box FallBWOs, midges, small streamer windowsBWO emerger, RS2, zebra midge, olive bugger
Fly family · report suggests “BWO emerger”Blue-Winged Olive PatternsBWO describes a hatch group, not one fly. Nymph, emerger, dry, cripple, and spinner profiles must stay separate because they occupy different parts of the water column.See family guide ↗
Fly pattern · report suggests “RS2”RS2Start with the beadless architecture: two dark-dun Microfibett tails separated behind a slim, tightly twisted and visibly segmented dubbed abdomen; a fuller thorax; and saddle-hackle web clipped into a short angled wing bud. Rim Chung's original-style form uses natural beaver dubbing and hackle web. CDC- or Antron-wing ties, beads, curved hooks, flash, and tailless Avatar-style flies must remain labeled variations.See photos & how to fish it ↗+ 2 more reviewed guides in the Fly Box Cold-season windowsMidges and sparse blue-winged olivesZebra midge, thread midge, RS2, small pheasant tail
Fly pattern · report suggests “Zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it ↗
Fly family · report suggests “thread midge”Midge Patterns by StageMidge wording can mean a threadlike larva, wing-padded pupa, film emerger, tiny adult, or visible cluster. Those profiles fish at different depths.See family guide ↗+ 2 more reviewed guides in the Fly Box 01
Start with the canyon rules and flow check before choosing a pull-off, because Blacksmith Fork is a better one-section river than an aimless road-hopping river.
02
Fish upstream carefully through one or two productive pockets at a time rather than charging past short seams that reload under stable flow.
03
Use dry-droppers and light nymphs first when the river is clear, then switch to a small streamer only when deeper slots or cover justify it.
04
If public access looks ambiguous or a promising bank would require walking private ground, move to the next clearly legal entry instead of rationalizing it.

Common questions
Before you leave.
When can I fish the Blacksmith Fork canyon section?+
Utah closes the special-regulation canyon water from April 15 until 6 a.m. on the second Saturday of July, so always confirm the current guidebook before the trip.
Which gauge should I trust for this page?+
Use RiverReports for the quick read, but keep USGS 10113500 open as the official backstop for Blacksmith Fork above the diversion dam near Hyrum.
Is Blacksmith Fork a float river?+
No. This page is built as a wade-only canyon trout plan with short public or clearly legal entries.
What is the biggest access mistake here?+
Assuming that roadside proximity means you can step onto any bank or streambed. Utah's stream-access rules still control where you can legally walk and fish.
