Not today. Make another plan.

Best option: Float. A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

These scores compare the risks of wading, bank fishing, and floating.

Wade2/100

Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.

Bank / edgeNot recommended

This report does not recommend bank fishing on this reach.

Your plan

Today's Logan River plan.

The Logan fishes best when RiverReports and USGS 10109000 show stable flow, runoff is no longer pushing every seam, and you keep the day centered on legal Highway 89 access. It is tempting to treat the whole canyon like open roadside water, but special fishing rules above Card Canyon Bridge and Utah's stream-access limits mean the cleanest trips stay tied to named public entries and conservative wading.

Check first
The Utah Fishing Guidebook sets special Logan River rules above Card Canyon Bridge, including a two-fish combined trout-and-whitefish limit and artificial-flies-and-lures rules through the Red Banks area.
Try
Pick one campground or pull-off area and fish it thoroughly before moving because Logan rewards repetition more than random canyon hopping.
Leave when
Skip when smaller streams are still high and swift, the river is carrying fresh color, thunderstorm runoff is building, or your access plan depends on wandering through posted private water.

How to fish it

How to fish Logan River today.

The best Logan days come after runoff settles enough to reveal clear pocket-water lanes, edges, and softer bankside shelves. If smaller streams are still surging, if the water is carrying fresh color, or if your access plan depends on wandering through posted private stretches, shorten the day or move to a clearer nearby canyon stream.

01

Stable medium flow

The best all-around window for pocket-water nymphing, dry-dropper coverage, and selective dry-fly shots where fish show.

02

Low clear summer flow

Fish early, lengthen leaders, and approach soft seams from below because the easiest roadside water gets pressured quickly.

03

Runoff or swift smaller stream push

Stay on obvious edges and softer inside current, and do not assume every roadside crossing remains reasonable.

04

Cold shoulder-season flow

Shrink the water, fish slower buckets and tailouts, and keep expectations tied to a few productive drifts rather than covering miles.

Fishing words used on this page
U.S. Geological Survey (USGS) gauge
A USGS gauge is an official river station that measures flow or water height.
Cubic feet per second (cfs)
Cubic feet per second, or cfs, shows how much water passes the gauge each second.
Nymph
A nymph is a young water insect. Anglers also use the word for a fly that copies it.
Seam
A seam is the line where fast and slow water meet.
Tailout
A tailout is the shallow, slower water at the lower end of a pool.
Attractor fly
An attractor fly is bright or bold. It draws a strike without copying one exact insect.
Blue-winged olive (BWO)
Blue-winged olives, or BWOs, are small mayflies that often hatch in cool or cloudy weather.
Caddis
Caddis are small water insects. The adults look a little like tiny moths.
Dry-dropper
A dry-dropper rig has a floating fly with an underwater fly tied below it.
Emerger
An emerger copies an insect as it rises from below the water toward the surface.
Why this call

Why this score

Best mode nowHurts

Float: A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

FlowUse caution

USGS shows 69 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1971-2025, 55 readings) show a median near 143 cfs and a low-water marker near 76 cfs; today's flow is unusually low for the date. Low water can make fish spooky, warm, pressured, or concentrated; check temperature and handling risk.

HeatUse caution

The current NWS air forecast is about 86F. This is an air forecast, not a water-temperature reading. Fish early and check the river with a stream thermometer.

Short-term weatherUse caution

The forecast has storm or heavy-precipitation risk, so timing and access matter more than the score alone.

Public alertUse caution

An active public alert is in effect near this forecast point, so the score is capped at caution until conditions are checked. NWS alert: Special Weather Statement issued August 22 at 8:25PM MDT by NWS Salt Lake City UT.

Trip notes

Trip notes

Check these before you choose a reach.

Best flows

Best on stable medium summer and early-fall flows that expose clear pocket-water seams without turning every crossing into a runoff problem.

When to leave

Skip when smaller streams are still high and swift, the river is carrying fresh color, thunderstorm runoff is building, or your access plan depends on wandering through posted private water.

Local plan

Base in Logan, choose one area such as Bridger or Preston Valley, fish it hard for a short morning or evening session, and move only if the water quality or pressure truly demands it.

Backup water

Blacksmith Fork River is the cleanest nearby backup when you want a more tightly framed public canyon plan, while Weber River makes more sense if Logan is blown out or overpressured.

What to try

Access and safety

Logan River access and rules.

Use these places as starting points. Open the access link below and check posted signs before you park or enter. On Logan River, special Utah rules apply above Card Canyon Bridge. From Card Canyon Bridge upstream to Red Banks Campground, and farther upstream to the Idaho line under the listed guidebook sections, anglers should recheck the current Utah Fishing Guidebook for the two-fish trout-and-whitefish combined limit, artificial-flies-and-lures requirements, and seasonal closure details before fishing.

Spring Hollow area

A practical lower-canyon public starting point where Highway 89 access keeps a half-day trout plan simple.

Bridger Campground

A named Forest Service access zone about six miles east of Logan with direct river proximity and easy orientation.

Preston Valley and Red Banks area

Useful upper-canyon staging water when you want cooler flow and are ready to track the special fishing rules closely.

Good roadside access does not erase Utah's private-bed rules. Enter at obvious public places and stay clear of posted private stretches.

Smaller streams can run high and swift even when the main river looks manageable from the road, so treat every crossing as a fresh decision.

The easiest pull-offs receive the most pressure. A short walk from a named entry often fishes better than the first obvious roadside pool.

Quick answers

Quick Logan River answers.

What gauge should I check for Logan River?

Start with RiverReports for the fast chart view and keep USGS 10109000 open as the official flow backstop when you decide whether runoff has settled enough to wade safely.

Does Logan River have special fishing rules?

Yes. Logan River has special Utah guidebook rules above Card Canyon Bridge, so check the current Utah Fishing Guidebook before you assume the standard statewide trout rules apply.

Is Logan River mostly roadside access?

It is roadside-friendly compared with many western trout streams, but the cleanest trips still start from named public entries and respect Utah's private-bed access limits.
