Your plan
Today's Colorado River plan.
The Colorado River at Lees Ferry is one of Arizona's most important trout trips because cold dam releases, clear water, canyon access, and special fishing rules all meet in one place. The best plan starts with flows, water temperature, and whether you are walking in or using a boat.
- Check first
- Use RiverReports and USGS 09380000 before choosing a wade, boat, or backhaul plan.
- Try
- Decide first whether the day is a walk-in day, a boat day, or a backhaul day. The reachable water changes the whole report.
- Leave when
- Skip or scale back when releases are changing faster than your access plan can handle, canyon wind is unsafe for your craft, heat and sun exposure are extreme, the backcountry permit or boating setup is not squared away, or rule boundaries are unclear.

How to fish it
How to fish Colorado River today.
Expect clear-water trout fishing where small changes in dam release, light, wind, and boat traffic can change the best tactic. Low, clear, bright water favors long leaders, small flies, and careful presentations. Higher or changing releases make edge fishing, heavier nymph rigs, and boat planning more important.
Low or steady release
Wade and walk-in options can be easier, but clear water demands longer leaders, smaller flies, and careful angles.
Rising dam release
Move with the water, stay off low bars that may flood, and fish fresh edge water rather than standing in changing current.
Higher release
Boat or backhaul logistics become more important. Fish protected banks, softer seams, and shelves instead of forcing unsafe wades.
Cold clear water
Use small midges, scuds, and slim nymphs with clean drifts. Sight-fishing and long drifts often matter more than changing flies every cast.
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.
- Technical fishing
- Technical fishing means the fish are hard to fool, so careful casts and natural drifts matter.
- Nymph
- A nymph is a young water insect. Anglers also use the word for a fly that copies it.
- Presentation
- Presentation means how you cast and move the fly so it looks natural to a fish.
- Riffle
- A riffle is shallow, fast water broken by rocks.
- Seam
- A seam is the line where fast and slow water meet.
- Attractor fly
- An attractor fly is bright or bold. It draws a strike without copying one exact insect.
- 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.
Why this call
Why this score
Water temperatureUse caution
USGS water temperature is about 69.8F. USGS marks the temperature data provisional and may revise it. Fish early and stop if handling stress is likely.
FlowHelps
USGS shows 8,170 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1922-2025, 104 readings) show a typical middle range of 8,030 cfs to 15,900 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.
SeasonHelps
Summer: The river stays cold, but desert heat, sun exposure, and afternoon wind make early starts, water, and shade important.
Public alertsHelps
No active NWS alert was returned for this forecast point.
Fishing usefulnessHelps
Skip or scale back when releases are changing faster than your access plan can handle, canyon wind is unsafe for your craft, heat and sun exposure are extreme, the backcountry permit or boating setup is not squared away, or rule boundaries are unclear.
Trip notes
Trip notes
Check these before you choose a reach.
Use the Lees Ferry release trend and water temperature together. Stable releases are the easiest planning window. Rising or changing releases should move anglers off low bars and toward safer edges, boat control, or a later check.
Skip or scale back when releases are changing faster than your access plan can handle, canyon wind is unsafe for your craft, heat and sun exposure are extreme, the backcountry permit or boating setup is not squared away, or rule boundaries are unclear.
Decide walk-in versus boat first. Walk-in anglers should start with legal bank access near Lees Ferry. Boat anglers should verify permit, ramp, PFD, wind, and release timing before choosing fly weight or drift length.
If Lees Ferry is poor because of wind, releases, permits, or heat, compare smaller Arizona trout waters such as Canyon Creek, Black River, or the Little Colorado only after checking their current rules and access.

Access and safety
Colorado River access and rules.
Use these places as starting points. Open the access link below and check posted signs before you park or enter. Verify current NPS and Arizona rules before fishing. NPS lists the Glen Canyon Dam to beginning of Paria Riffle reach as artificial fly and lure only, barbless hooks only, and a 2-rainbow-trout daily limit. Rainbow trout taken from this portion must be killed and retained as part of the bag limit or immediately released. The area immediately below Glen Canyon Dam, posted with buoys, is closed to entry.
Lees Ferry launch ramp
NPS lists a public launch ramp at Lees Ferry. The ramp is the main staging point for upriver boat and backhaul plans.
Walk-in bank water near Lees Ferry
NPS states permits are not required for visitors only hiking or fishing along the riverbank.
Glen Canyon Dam to Lees Ferry area
Watercraft users in this area need a Lees Ferry Backcountry Permit from the self-service kiosks near the launch area.
Paria Riffle area
Important rule boundary. NPS separates rules from Glen Canyon Dam to the beginning of Paria Riffle and from Paria Riffle to Navajo Bridge.
Marble Canyon and Navajo Bridge
Useful travel and orientation points. NPS notes services at Marble Canyon and recommends stopping at Navajo Bridge.
Lees Ferry is reached from Page by US 89 and US 89A, then a paved road into the ferry area.
Do not block the launch ramp. NPS notes a 30-minute length-of-time restriction at public access courtesy docks and ramps.
The river is cold and clear even when desert air is hot. Wading and boating plans should account for cold-water exposure.
If using a boat, check NPS vessel restrictions, horsepower rules at high releases, PFD rules, and the backcountry permit requirement.
Summer heat, canyon wind, and limited shade can be more dangerous than the fishing looks from the parking lot.
