Wade and Float have the same top score. Use current access, footing, weather, and local rules to choose.

Wade58/100

Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.

Bank / edgeNot recommended

This report does not recommend bank fishing on this reach.

Float58/100

A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.

Your plan

Today's Eagle River plan.

The Eagle is a productive valley trout river when flows are clear and stable. It fishes differently from the upper Vail water to the lower Wolcott and Gypsum reaches, so the gauge and access plan should come first.

Check first
RiverReports and USGS 09067020 give the best quick read for the Avon area.
Try
Pick the reach after checking both flow and public access.
Leave when
Skip or scale back when runoff is pushy, thunderstorms muddy the valley, lower-river temperatures are stressful, public access or private boundaries are unclear, or slick cobble makes crossings unsafe.

How to fish it

How to fish Eagle River today.

The Eagle rewards flexible anglers. Nymph deep during cold or off-color water, switch to caddis and mayflies when fish look up, and avoid treating every reach as equally public or equally trout-safe in summer.

01

Low and clear

Use longer leaders, lighter tippet, smaller mayfly or midge patterns, and careful bank approaches.

02

Stable medium flow

This is the most flexible window for nymphs, dry-droppers, caddis dries, and soft-hackle swings.

03

Runoff or stain

Fish inside bends, banks, and softer edges only if wading is safe. Streamers and larger stonefly nymphs become more useful.

04

Warm lower river

Check temperature. If trout handling risk is high, move upstream, fish early, or choose a colder option.

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.
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.
Emerger
An emerger copies an insect as it rises from below the water toward the surface.
Midge
Midges are tiny flies and a common trout food, especially in cold water.
Pale morning dun (PMD)
Pale morning duns, or PMDs, are light-colored mayflies that often hatch in warmer months.
River reach
A reach is one named section of a river or stream.
Soft hackle
A soft-hackle fly has moving fibers that can look like an insect rising through the water.
Why this call

Why this score

FlowUse caution

USGS shows 38 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (2000-2025, 26 readings) show a median near 141 cfs and a low-water marker near 68 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.

Short-term weatherUse caution

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

Best mode nowUse caution

Wade: Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.

SeasonHelps

Summer: Caddis, PMDs, stones, and terrestrials matter, but lower-river temperatures should be checked.

WeatherHelps

The current NWS air forecast is about 57F, and the next 24-hour high reaches about 73F. Slight Chance Showers And Thunderstorms.

Trip notes

Check these before you choose a reach.

Best flows

Use the Avon gauge trend more than one magic number. Stable or slowly falling clear flow is the best all-around trout signal. Runoff, storm stain, or warm lower-river afternoons should move the plan upstream, earlier, or to another route.

When to leave

Skip or scale back when runoff is pushy, thunderstorms muddy the valley, lower-river temperatures are stressful, public access or private boundaries are unclear, or slick cobble makes crossings unsafe.

Local plan

Start with the Avon gauge and weather, then choose Avon/Edwards for a shorter wade check, Wolcott/Eagle for a broader valley plan, or Gypsum only when temperature and access still support trout handling.

Backup water

If the Eagle is too high, warm, stained, or access-limited, compare the Fryingpan, Roaring Fork, or middle Colorado after checking each route's current flow and rules.

Access and safety

Eagle River access and rules.

Use these places as starting points. Open the access link below and check posted signs before you park or enter. Check the current Colorado fishing rules and any section-by-section special rules before fishing. Posted access signs and private property boundaries control the day even when a map shows the river nearby.

Avon and Edwards town water

Useful public starting areas with paths, parks, and nearby services. Confirm posted access boundaries.

Wolcott to Eagle area

Mix of public and private water where open space and BLM parcels matter for planning.

Gypsum and lower Eagle

Lower-valley water can fish well, but temperature, boating, and private property are bigger factors.

CPW notes that Eagle County and CPW have supported public access opportunities in the lower valley.

Do not cross or stop on private land unless a public access point clearly allows it.

Spring runoff can make otherwise familiar crossings unsafe.

Lower-river summer afternoons can become a trout-handling problem even when fishing is legal.

Compare another river

If this water does not fit the day, check another report before you start the drive.

Quick answers

Quick Eagle River answers.

What part of the Eagle River does this report cover?

It focuses on the public-facing Avon, Edwards, Wolcott, Eagle, and Gypsum area rather than every headwater smaller stream.

Is RiverReports or USGS better for the Eagle?

Use RiverReports for the quick chart and USGS 09067020 as the official Avon monitoring source.

When is the Eagle hardest to fish?

High runoff, muddy storm bumps, and hot lower-river afternoons are the main problem windows.

What flies should I bring?

Bring midges, BWOs, caddis, PMDs, yellow sallies, stonefly nymphs, terrestrials, and a few streamers.
