A Skagit report for Concrete, Rockport, and Marblemount planning, with flow checks, salmon and steelhead guardrails, access, weather, and fly tactics.

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

Wade · Best fit74/100

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

Bank / edge74/100

Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.

Float74/100

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

River strategy

Fish the Skagit as a big river with current rules.

The Skagit is large, beautiful, and heavily regulated. Use the Concrete gauge for upper and middle river flow, then verify WDFW emergency rules for salmon, steelhead, trout, and gamefish before choosing a plan.

Use Concrete flow for the core report, not lower-valley flood-only context.
Active and recent emergency rules make salmon and steelhead planning rule-sensitive.
The best fly plan depends on clarity, bar access, and whether the target species is legal.
Avoid redds, spawning fish, and side channels during sensitive periods.

Why this score moved

FlowUse caution

USGS shows 10,300 cfs with a stable over about 6 hours trend. same-date USGS history (1925-2025, 101 readings) puts normal around 18,100 cfs and the low-water marker near 10,500 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.

SeasonHelps score

Summer: Upper-river access and trout or char context depend on rules and temperature.

WeatherHelps score

The NWS forecast is about 76F with Sunny.

Public alertsHelps score

No active NWS alert was returned for this forecast point.

Fishing usefulnessHelps score

Skip the Skagit when WDFW rules do not clearly support the target species, when high water erases safe bars, when protected fish are concentrated, or when the day depends on lower-valley assumptions that do not match Concrete or Marblemount conditions.

Read the water

What changes the plan.

The Skagit is most useful when flow is stable enough for safe bank or boat planning and WDFW rules clearly support the species. If rules are unclear, do not fish it on assumptions.

Moderate clear flow

Fish softer seams, side channels, and bar edges where legal.

High flow

Use boat ramps and observation points; avoid wading heavy current.

Dropping after rain

Often the best time to evaluate clarity and safe access.

Low clear water

Long leaders, smaller flies, and careful approach become more important.

Field plan

Fish it with intention.

Best flows

Use USGS 12194000 near Concrete as the core upper and middle Skagit trend. Stable or easing flows with workable clarity are the best fit; high flows, cold heavy current, or unclear species rules should shorten or cancel the trip.

When to skip

Local plan

Choose one anchor before fishing: Rasar State Park for a public middle-river base, Rockport or Marblemount for upper-river context, or the Concrete gauge corridor when flow and weather are the main decision.

Backup water

If Skagit flow, clarity, or rules do not line up, compare the Sauk for a tributary plan only if legal, the Skykomish for another west-side rules-first river, or the Yakima for a more predictable trout-centered day.

Hatches & flies

Bring a flexible box.

TimingWhat to watchUseful flies

March to MayBWOs, midges, Skwalas where present, early caddis, and high-water nymphingBWO emerger, zebra midge, Skwala dry, caddis pupa, stonefly nymph

Reviewed family · report says “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

Reviewed pattern · report says “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 + 3 more reviewed guides in the Fly Box

June to JulyCaddis, PMDs, Golden Stones, small yellow sallies, and evening soft hacklesElk hair caddis, PMD emerger, Chubby Chernobyl, soft hackle, perdigon

Reviewed pattern · report says “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

Reviewed family · report says “PMD emerger”Pale Morning Dun PatternsPMD names an insect group, not one fly. Pale nymphs, trailing-shuck emergers, upright or low-riding duns, cripples, and spent-wing spinners stay visibly separate.See family guide + 3 more reviewed guides in the Fly Box

August to SeptemberHoppers, ants, beetles, small caddis, and low-light streamer windowsFoam hopper, ant, beetle, X-caddis, olive sculpin, small leech

Reviewed family · report says “Foam hopper”Grasshopper PatternsHopper patterns share a substantial body and long rear-leg impression, but foam, deer hair, wing construction, and waterline differ widely among named patterns.See family guide

Reviewed family · report says “ant”Ant PatternsAnt patterns can be foam, fur-bodied, winged, or sunken. The narrow waist and paired body lobes matter more than one material recipe.See family guide + 4 more reviewed guides in the Fly Box

October to FebruaryOctober caddis, BWOs, midges, eggs where legal, and winter steelhead contextOctober caddis, BWO emerger, midge pupa, egg pattern where legal, intruder

Reviewed family · report says “October caddis”October Caddis PatternsOctober Caddis names a hatch group. Amber or orange pupae, soft-hackle or wet forms, and large tent-wing adults fish at different levels.See family guide

Pick a legal target before choosing a fly.

On big gravel bars, fish the first safe travel lane instead of wading toward the middle.

Use swung flies, streamers, or nymphs only where methods are legal for the target species.

Avoid side channels with spawning fish or exposed redds.

Use the Concrete hydrograph to decide whether your return route may flood.

Access & responsibility

Know the entry. Know the exit.

Check WDFW regulations and emergency rule changes before fishing the Skagit, especially for salmon, steelhead, bull trout/Dolly Varden, gamefish seasons, and reach-specific closures.

Rasar State Park

A verified public recreation anchor for middle Skagit planning.

Rockport and Marblemount

Upper-river towns for big-river access, weather, and road checks.

Common questions

Before you leave.

What should I check before fishing Skagit River?+

WDFW emergency rules, Concrete flow, salmon or steelhead status, park access, weather, and clarity

Which flow should I use for Skagit River?+

Use USGS 12194000 Skagit River near Concrete for the upper and middle river report.

Where should I start on Skagit River?+

Start with Rasar State Park, Rockport, Marblemount, and other legal public access points after checking WDFW rules.

Can I wade Skagit River?+

Only on safe margins and gravel edges at suitable flows. This is a large cold river where crossing is usually a poor plan.
