Safety overrides tacticsNo approach recommended
The active safety or closure reason takes priority over wading, bank fishing, and floating guidance.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

How to fish it
Plan this as a remote Uinta trout creek, then verify the exact reach.
Yellowstone Creek is a Utah stream in Duchesne County, not the Vermont coordinate that came through in the seed data. There is no verified public live gauge on the creek itself, so this page uses the nearby Yellowstone River at Bridge Campground gauge as drainage context and keeps the fishing advice practical rather than overstated.
- Use the USGS Bridge Campground gauge for broad drainage trend, but scout the actual creek before committing to a wade.
- Expect a small-water trout approach: dry-droppers, short casts, careful wading, and quick fish handling.
- Check Utah DWR rules and Fish Utah before choosing harvest, gear, or a specific reach.
- If water is low and warm, fish early, carry a thermometer, and move to colder water or stop trout fishing.
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 3 at 10:00PM MDT by NWS Salt Lake City UT. Check public safety sources before going.
FlowHelps score
USGS shows 73 cfs with a stable over about 6 hours trend. Today's flow is within the normal seasonal range of 50 cfs to 117 cfs. Weather, water temperature, and access are the next checks.
SeasonHelps score
Early summer: Often the best blend of cool water, clearing flows, and active trout once runoff settles.
WeatherHelps score
The NWS forecast is about 67F with Mostly Clear.
Fishing usefulnessHelps score
Skip Yellowstone Creek when forest roads are muddy or closed, when lightning or runoff makes a high-country day unsafe, when downstream gauges show a sharp runoff pulse, or when low warm water would make trout handling poor.
Read the water
What changes the plan.
The best window is usually after dangerous runoff drops and before late-summer heat or drought makes trout handling questionable. Stable flows, cool nights, and afternoon insect activity are the best signs. Skip the creek during high water, muddy road conditions, lightning risk, or warm low-flow afternoons.
Stable cool flow
Best all-around window for dry-droppers, light nymphs, and careful pocket-water fishing.
Runoff or storm bump
Watch the downstream gauge trend, but make the creek decision on clarity, depth, and road safety.
Low clear summer water
Use longer leaders, smaller dries, stealth, and morning sessions; stop if the water warms.
Cold shoulder seasons
Fish slower nymphs and midges during the warmest part of the day, and expect a short bite window.
Your trip plan
Know when to go—and when to skip it.
Best flows
There is no verified public live gauge on the creek itself. Use USGS 09292000 at Bridge Campground and USGS 09292500 near Altonah as drainage context, then make the final call from actual creek depth, clarity, and temperature.
When to skip
Skip Yellowstone Creek when forest roads are muddy or closed, when lightning or runoff makes a high-country day unsafe, when downstream gauges show a sharp runoff pulse, or when low warm water would make trout handling poor.
Local plan
Build the day around scouting one reachable public section, checking the Fish Utah map, and using Ashley National Forest road and campground context before committing. Keep the fly box simple and make water temperature part of every decision.
Backup water
If Yellowstone Creek is not ready, compare the Duchesne for a larger nearby freestone, the Green for a high-confidence tailwater day, or the Weber when a different Utah trout river fits the weather better.
Hatches & flies
Bring a flexible box.
TimingWhat to watchUseful flies
Late April to MayMidges, BWOs, early caddis, and short pre-runoff nymph windowsZebra midge, BWO emerger, pheasant tail, hare's ear, caddis pupa
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 “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 ↗+ 3 more reviewed guides in the Fly Box June to early JulyRunoff edges, golden stones, caddis, PMDs, and attractor dry-dropper windowsGolden stone nymph, elk hair caddis, PMD emerger, stimulator, perdigon
Fly family · report suggests “Golden stone nymph”Golden Stonefly PatternsGolden stonefly wording may describe the insect, nymph, or dry. Nymph tones can range from yellow-gold to amber and brown, while adult patterns require a distinct winged surface silhouette.See family guide ↗
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 ↗+ 3 more reviewed guides in the Fly Box Mid-July to SeptemberCaddis, small mayflies, ants, beetles, hoppers, and evening spinner fallsParachute Adams, X-caddis, foam ant, beetle, small hopper, rusty spinner
Fly pattern · report suggests “Parachute Adams”Parachute AdamsThe upright light post and horizontal parachute hackle are the defining visual cues. The classic pilot example uses a gray-brown body and divided tail, but color and size variations should be labeled instead of treated as identical.See photos & how to fish it ↗
Fly pattern · report suggests “X-caddis”X-CaddisIdentify the X-Caddis by the combination of a sparse translucent Zelon-style trailing shuck, slim dubbed body, tented deer- or elk-hair wing, small clipped head, and no palmered body hackle. The separately photographed Elk Hair Caddis has a higher, hackled adult footprint and no defining trailing shuck. The natural-adult photograph explains the caddis tent-wing silhouette, but it does not turn the X-Caddis into an exact adult-species imitation.See photos & how to fish it ↗+ 4 more reviewed guides in the Fly Box October to early winterBWOs, midges, small streamers, and slower cold-water nymphingBWO emerger, midge pupa, soft hackle, small olive bugger, jig nymph

Fly family · report suggests “midge pupa”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 ↗+ 3 more reviewed guides in the Fly Box 01
Start with a small attractor dry and a light dropper so you can cover pocket water without constant rig changes.
02
Fish upstream from below the fish, keep false casts low, and avoid standing in the next pool before you fish it.
03
In clear low water, switch to a single dry or a tiny unweighted nymph instead of forcing heavy split shot.
04
After rain, check the downstream trend and fish softer edge water only if the creek itself is safe and clear enough.
05
Carry a thermometer and stop trout fishing when water temperatures make quick releases unreliable.

Common questions
Before you leave.
What should I check before fishing Yellowstone Creek?+
Utah DWR guidebook, Fish Utah map, stream-access rules, Ashley National Forest road/campground status, USGS 09292000, NWS weather, and water temperature
Which flow should I use for Yellowstone Creek?+
Use USGS 09292000, Yellowstone River at Bridge Campground, as drainage context only. It is not an exact Yellowstone Creek gauge, so confirm creek depth, clarity, and temperature on-site.
Where should I start on Yellowstone Creek?+
Start with Fish Utah, Ashley National Forest south-slope recreation pages, and the Bridge Campground corridor. Then verify land ownership and posted access at the specific pullout or trail you plan to use.
Can I wade Yellowstone Creek?+
Often yes in normal small-water conditions, but runoff, storm bumps, slick rocks, and cold water can still make it unsafe. If the creek is pushy or dirty, wait for a better window.
