Your plan
Today's Tsiu River plan.
The Tsiu is a remote Yakutat-area river known mainly for coho runs. Because there is no verified public gauge for this report, the best planning starts with current weather, recent rain, air-charter logistics, and ADF&G emergency orders.
- Check first
- Confirm current ADF&G Yakutat rules and emergency orders before booking or fishing.
- Try
- Call or check with local Yakutat air services before treating the trip as confirmed. Weather can change flight plans.
- Leave when
- Skip or delay the Tsiu when ADF&G emergency orders change the plan, storms threaten aircraft movement, recent rain erases visibility, bears or tides make the chosen water unsafe, or the trip lacks satellite communication and a realistic exit plan.

How to fish it
How to fish Tsiu River today.
Fish the Tsiu only when the trip logistics and river conditions line up. Good coho fishing usually depends on enough rain to move fish, enough clarity to present a fly, and safe access. If the river is too low, too warm, blown out, or inaccessible by aircraft, the best choice is to wait or switch plans.
Low and clear
Use lighter sink tips or floating-line presentations, smaller streamers, and careful approaches. Coho may hold lower, move less, or wait near tide-influenced water.
Fresh rain and rising water
Rain can pull coho into the river, but clarity and safety decide whether it is fishable. Watch for debris, soft banks, and fast color changes.
High or blown out
Do not force it. Heavy coastal rain can make the river unsafe and unfishable. Wait for dropping water or use a local alternate.
Warm, dry spells
Low warm water can stress salmon. ADF&G archived Yakutat reports have warned that warm, dry conditions can reduce water levels and stress coho.
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.
- Presentation
- Presentation means how you cast and move the fly so it looks natural to a fish.
- Streamer
- A streamer is a fly that looks like a small fish, leech, or other swimming food.

Trip notes
Trip notes
Check these before you choose a reach.
Use National Weather Service forecasts, NOAA Alaska-Pacific River Forecast Center context, recent rainfall, and local air-service reports in place of a live gauge. The best fishing window is usually fishable color with moving coho and a safe weather window for both arrival and exit.
Skip or delay the Tsiu when ADF&G emergency orders change the plan, storms threaten aircraft movement, recent rain erases visibility, bears or tides make the chosen water unsafe, or the trip lacks satellite communication and a realistic exit plan.
Confirm Yakutat-area rules and emergency orders first, then call the access provider for runway or landing status, recent rain, bear activity, and fish movement. Pack for a weather delay rather than a same-day certainty.
If the Tsiu is weathered out, off-color, or legally uncertain, research the Situk River first, then Yakutat road-area waters such as Lost River and Tawah Creek, or other remote systems only with current local access information.

Access and safety
Tsiu 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 ADF&G Southeast Alaska sport fishing rules, the Yakutat Area special fishing rules, and all emergency orders before fishing. Emergency orders supersede published rules, and salmon limits, gear rules, king salmon restrictions, and saltwater/freshwater boundaries can change.
Remote air access from Yakutat
ADF&G describes the Tsiu as an outlying remote system and advises checking with local air taxis for charter service.
Tidewater and lower river planning
Coho movement, tides, rain, and visibility can all matter near coastal water. Confirm local conditions before choosing a landing or fishing zone.
Yakutat fallback waters
If the Tsiu is inaccessible or unfishable, research Yakutat-area alternatives through ADF&G rather than forcing the original plan.
This page does not identify a public road access point because the Tsiu is treated here as a remote fly-out planning destination.
Confirm land status, aircraft landing conditions, guide or air-taxi availability, and weather windows before travel.
Carry satellite communication, bear-safe food handling, first aid, rain gear, and a conservative exit plan.
Respect private, tribal, commercial, and subsistence activity. Remote water is not a license to ignore local use patterns.

No. This page treats the Tsiu as a remote Yakutat-area system. ADF&G notes that anglers should check with local air taxis for charter service to outlying systems like the Tsiu.
What is the main fish to plan around?
Coho salmon are the main planning target. ADF&G describes the Tsiu as known mainly for coho runs.
Is there a live flow gauge for the Tsiu River?
No verified public RiverReports or USGS live gauge is used for this report. Use weather, recent rain, local reports, and conservative judgment instead.
What should I check before booking a trip?
Check ADF&G Yakutat rules and emergency orders, NWS weather, local air-taxi availability, bear-safety needs, and backup plans for poor water or flight delays.
