🎣 TACTICS RIGHT NOWDry FlyDry fly fishing is done at Lees Ferry until fall. Any residual midge clusters at dawn (5:30-6:45am) are too sparse and brief to target reliably—hatches measured in minutes on the rare morning they happen at all. Dry-dropper combos (CDC Shuttlecock #18-20 with #22 midge pupa trailer) function purely as a nymph delivery systemnot true dry fly fishing. Chubby Chernobyl #14-16 works as an indicator dry in shallow vegetated riffles at first light but you're fishing the dropper. Realistic expectation: 0-1 surface fish at dawn on a lucky daythen commit fully to nymph rigs by 6:45-7:00am. Canyon temps exceeding 105°F by late morning—surface activity nonexistent. Do not plan a trip around dry fly fishing at Lees Ferry in mid-June.
NymphScud/worm rigs dominate completely and will hold through summer. San Juan Worm #14 (red/pink) on point with tungsten-bead Scud Muffin #12-14 or Orange Scud #12-14 as trailer remains the primary setup—this rig is catching the vast majority of fish right now. Orange and pink scuds dead-drifted continue as the hot ticket—fish keying on stranded naturals displaced by generation swings. Dual midge rigs no longer worth running; scud/worm outproduces everything. Flows holding at ~8200 CFS base with generation swings up to 12000 CFS; set indicator at 1.5x water depth and re-adjust frequently as levels change throughout the day. Switch to ginger scuds during afternoon generation ramps when rising water dislodges naturals from weed beds. Downstream temps now 59-60°F—fish concentrated in cooler upstream reaches within 2-3 miles of the dam. Drought-reduced annual releases (6.0 mafLake Powell at 25%) keeping base flows lowwhich is improving wade access near the ramp and state campground. Long leaders (10-14 feet)micro split shot #6 or #4and 5X-6X fluorocarbon tippet essential. If fish flash but refusedrop to #22 midge pupae (black/grey) on 7X as a confidence dropper. Dead drift in gin-clear water—constant upstream mending critical. Presentation depth is everything; flies should tick bottom.
StreamerOlive Woolly Bugger #6-8 and Cone Head Sculpzilla #6-8 (black/olive/tan) on 200-grain sink-tip producing on deeper shelves when drifting or anchoring near 4-Mile Bar and upstream structure. Weighted Slumpbuster effective in deeper slots. Sink-tip bite remains a consistent option for targeting browns in specific lies—especially productive in the cooler upper 2-4 miles where water temps remain in the low 50s. As downstream temps push toward 60°Fbrowns holding tighter to structure and shade. Harvest encouraged under bounty program ($33/fish standard$300 for tagged fish).
FORECASTFishing remains productive but the summer squeeze is tightening. Flows holding around 8,200 CFS base—stable and wadeable in spots. Downstream water temps now pushing 59-60°F and climbing; if they breach 60°F consistently through the next week, expect catch rates to compress noticeably as fish retreat further upstream. The first 2-3 miles below the dam (49-51°F water) are now where nearly all the action is. Guides still reporting 8-12 fish per rod on productive mornings with scud/worm rigs, but the window to hit those numbers shrinks daily. Lake Powell at just 25% capacity—Bureau of Reclamation's drought-reduced 6.0 maf release tier means base flows will stay low through summer, which is a mixed blessing: better wade access but warmer downstream reaches. Monsoon season approximately 2-3 weeks out (early July)—when it arrives, expect brief afternoon thunderstorms and potential turbidity spikes from Paria River and side canyon washes. The next 1-2 weeks offer a shrinking but still fishable window before peak summer conditions set in fully. If you have a June trip planned, commit to early mornings and fish the upper 2-3 miles exclusively. July and August will be tough until monsoons bring some relief.Full desert summer conditions now in effect. Mornings 58-68°F, afternoons 105-112°F—canyon temperature swings of 40-50+ degrees daily. Sun protection non-negotiable: SPF 50+, hat, long sleeves, buff, and polarized sunglasses. Canyon thermal winds building by 10am, gusting through afternoon. Monsoon season approximately 2-3 weeks away (early July)—isolated pre-monsoon thunderstorms possible. Hydrate aggressively—carry at least 3 liters per person minimum for any session. Plan to be off water by 10am as canyon heat becomes dangerous. Heat exhaustion risk is acute—canyon walls trap and amplify heat well above ambient temperature. This is the hottest and most demanding time to fish Lees Ferry. Check weather forecasts daily.
The Deal With Lee's Ferry
Before Glen Canyon Dam was completed in 1963, the Colorado River here ran warm and muddy - classic desert river conditions. The dam changed everything. Cold, clear water now releases from the bottom of Lake Powell at a constant 46-50°F year-round, creating ideal conditions for rainbow trout in a place where they have no business existing.
The result is a 15.5-mile tailwater fishery that runs from the dam to Lees Ferry proper, where the river enters Marble Canyon and begins its journey through the Grand Canyon. Arizona Game and Fish began stocking rainbows shortly after dam completion, and in 1981 designated this stretch as a Blue Ribbon fishery.
Glen Canyon Dam - the 710-foot concrete wall that accidentally created a world-class trout fishery
It's strange fishing. You're on the Colorado Plateau, surrounded by red rock canyon walls and Vermilion Cliffs, casting to fish that belong in Montana. The juxtaposition never quite makes sense, and that's part of the appeal.
Current Reality Check: The 2022 AGFD Data
Thirty years ago, Lee's Ferry was the Southwestern Mecca of big trout - anglers routinely experienced 40-fish days with multiple 20+ inch fish. The fishery has changed.
According to the Arizona Game and Fish Department's 2022 Annual Report, the picture is sobering:
- Rainbow trout were only 60% of the fish assemblage during autumn 2022 sampling - the lowest percentage observed since monitoring began in 1991
- Electrofishing catch-per-unit-effort (CPUE) hit record lows - the worst numbers in 31 years of monitoring
- Water temperatures were the highest ever recorded; dissolved oxygen at some of the lowest levels
- Non-native invasive species are increasing - smallmouth bass, green sunfish, bluegill, and black crappie are passing through the dam
The summers of 2022 and 2023 hit the fishery hard with low dissolved oxygen and elevated water temps. Fish are still there, but in lower numbers than historical highs.
What This Means for Anglers
AGFD's management goals provide realistic benchmarks:
- Target catch rate: At least 1 trout per hour ≥ 14 inches
- Trophy target: At least 0.1 trout per hour ≥ 20 inches (one per 10 hours)
- Healthy population indicator: 20-50% of fish should be under 6 inches (recruitment)
Recent trip reports indicate anglers are still catching solid rainbows in the 14-18 inch range, with occasional fish pushing 20+. The fish that are there tend to be healthy and robust - just fewer of them. Expect a good day to produce 10-20 fish, not the 40+ of years past.
What You're Fishing For
Rainbow Trout - The primary target. Wild fish ranging from 14-22 inches, with the occasional trophy pushing larger. These aren't stocked hatchery fish anymore - they've naturalized and reproduce in the river.
Brown Trout - Here's where it gets interesting. Browns are considered invasive and problematic because they prey on native species like the endangered humpback chub downstream in Grand Canyon National Park.
The Brown Trout Bounty Program
The National Park Service runs a Brown Trout Incentivized Harvest program that actually pays you to catch fish:
| Bounty Type | Payout |
|---|
| Standard brown trout (>6 inches) | $33 |
| Tagged brown trout (Sept-Oct) | $300 |
| Winter Bonanza (Nov-Dec) | Standard $33 + bonuses for tagged fish |
How it works:
- Catch a brown trout over 6 inches
- Record data on provided data card
- Deposit head and guts (with data card) at the freezer at Navajo Bridge Interpretive Center
- Collect payment
Requirements:
- Valid Arizona fishing license
- Barbless artificial lures/flies only
- No limit on harvest
This isn't a tourism gimmick - it's a serious conservation effort. Browns prey on and compete with native fish, threatening species that have called the Grand Canyon home for millennia. The program has been running since November 2020 and is expected to continue through at least 2025.
Pro tip: Browns concentrate on spawning gravel bars at Mile -4 and Mile -12 during November-December. The Winter Bonanza specifically targets these fish when they're most vulnerable.
Flow Conditions
Track Colorado River flows at Lees Ferry for real-time conditions.
Typical Flow Ranges
| Flow (CFS) | Conditions |
|---|
| 8,000-10,000 | Normal operations - good fishing, standard techniques |
| 10,000-15,000 | Higher but fishable - may need heavier weight |
| 15,000+ | High flow events - challenging but experienced anglers find fish |
| 3,000-8,000 | Lower flows - often excellent fishing during "Bug Flow" weekends |
Bug Flows: The Secret Weapon
The Bureau of Reclamation occasionally implements experimental "Bug Flow" releases - low, steady flows during weekends while maintaining normal fluctuating flows on weekdays for hydropower. During Bug Flow weekends, anglers catch an average of 1-2 more rainbow trout per day compared to fluctuating weekday flows.
Check the Bureau of Reclamation's Glen Canyon Dam operations page for current release schedules.
Water Temperature
Thanks to releases from the bottom of Lake Powell, water temperature stays remarkably consistent:
- Year-round range: 46-51°F
- Summer peak: May reach 51-52°F during hot summers
- No thermal stress during normal conditions - fish can be caught year-round
Regulations
The section from Glen Canyon Dam to the Paria River confluence (the main fishing water) has specific restrictions:
| Regulation | Details |
|---|
| Tackle | Artificial flies and lures only - no bait |
| Hooks | Barbless required |
| Daily limit | 2 rainbow trout (any size) |
| Brown trout | No limit - harvest encouraged |
| License | Arizona fishing license required |
Below Navajo Bridge to Separation Canyon, there's no limit on any sportfish species.
Important: Catch and release is strongly encouraged for rainbows. With CPUE at record lows, every fish you release helps the fishery recover.
Fly Patterns That Work
Lee's Ferry is a technical fishery dominated by small stuff. The food base consists primarily of scuds (freshwater shrimp), midges (50+ varieties), and aquatic worms. Forget the big dries and streamers - this is precision nymphing water.
Midges (Year-Round, Size #16-24)
Midges are the primary food source. During hatches, trout can be maddeningly selective.
Essential patterns:
- Zebra Midge (#18-22) - Black, grey, red, purple, olive. The standard bearer.
- RS2 (#20-24) - Gray or olive for picky risers
- WD-40 (#20-22) - Another small-water staple
- Griffith's Gnat (#18-20) - For surface feeders during emergences
- CDC Shuttlecock (#18-20) - One angler reported standard #20 patterns being ignored while tiny CDC shuttlecocks produced 30+ fish
Hatch timing: Midges hatch year-round, but the largest emergences occur in spring (March-May). When they come off, they often emerge in mass numbers for extended durations - fish move into riffles to feed on emerging bugs.
Scuds (Year-Round, Size #12-16)
Scuds are abundant and trout love them.
Color guide:
- Orange and pink - Often the hot ticket. When dam releases change water levels, scuds get stranded, die, and turn orange-pink. Fish key on dead-drift orange/pink patterns.
- Olive and tan - Natural colors for standard conditions
- Ginger - Effective during rising water from dam releases
Specific patterns:
- Scud Muffin (Rio's tungsten bead jig hook version) - Designed specifically for this fishery
- Ray Charles Scud (#14-16) - Classic producer
San Juan Worms (Size #12-16)
- Red San Juan Worm (#16) - Currently producing well according to recent reports
- Tan and claret colors
- Essential backup when scuds and midges aren't working
- Especially effective after rain or during rising water
Wooly Buggers and Streamers (Size #4-10)
- Olive, black, and brown Wooly Buggers
- Cone head Sculpzillas in black, olive, and tan
- Best fished with sink-tip line when wading
- More effective for brown trout than rainbows
Lee's Ferry rainbows currently average 14-18 inches - down from historical highs but still quality fish
Techniques
Nymphing (Most Productive Method)
The standard approach is a two-fly nymph rig under an indicator. This is how guides fish it and how 90% of fish are caught.
Recommended setup:
- Strike indicator (foam preferred) set at 1.5-2x water depth
- Lead fly: Scud or San Juan Worm (#12-14)
- Dropper (18-24 inches below): Zebra Midge or small nymph (#18-22)
- Micro split shot (#6 or #4) - often need more weight than you'd expect
- 5X-6X tippet - these fish are line-shy
Critical techniques:
- Set the hook on any indicator movement - fish here take subtly
- Slowly lift your rod at the end of each drift - trout often follow and eat on the final lift
- During midge hatches, consider dual midge patterns instead of scud/midge combo
- Downsize during tough conditions - #24 midges can make the difference
Drift Boat Fishing
Most anglers fish Lee's Ferry from a drift boat, covering large pieces of water. This is the most effective method because:
- The river is big (100-300 feet wide) and deep in many sections
- You can cover more holding water efficiently
- Access to productive mid-river structure impossible to reach wading
- Guides know where fish concentrate
Typical drift: 8-10 miles, covering water from near the dam to the Lees Ferry ramp.
Wade Fishing Options
Wade fishing is possible but more limited. Key access points:
Walk-in water below the boat launch:
- The primary shore access, referred to as "walk-in water"
- Fish heavy nymphs and split shot around rocks
- Expect smaller fish on average, but decent numbers
- Can get crowded during spring and fall - bring patience
Below State Campground:
- Good bank access and productive water
- Scuds and San Juan worms usually produce
- Warning: Watch current carefully - it can sweep you into dangerous water quickly
Hike-in options:
- Jackass Creek wash provides vigorous hike-in access
- Tanner Wash is another option
- Check with Grand Canyon National Park for current trail conditions
Reality check: Many anglers note it's tough to fish effectively without a boat. The river is large, and much of the shoreline is impassable. If wade fishing is your only option, focus on the walk-in areas and manage expectations.
Best Times to Fish
Time of Day
Early morning (6-10am): Generally best conditions. Fish are most active, midge activity begins, and you beat the afternoon crowds and heat.
Midday (10am-3pm): Often slower. During spring, massive midge hatches around noon can shut off fishing as fish become hyper-selective. On summer days, the desert heat becomes oppressive.
Evening (4pm-sunset): Can be productive, especially in summer. Fish become active again as temperatures moderate.
Weather factor: Impending weather changes make Lee's Ferry fish shut down. If a storm is approaching, fish often won't eat even when conditions look normal.
Seasonal Breakdown
| Season | Conditions | Notes |
|---|
| Winter (Nov-Feb) | Low pressure, good midge activity | Brown Trout Bonanza runs Nov-Dec. Minimal crowds. Water temp stable at 47°F. |
| Spring (Mar-May) | Best midge hatches, fish feeding aggressively | Most productive season. Sight-casting to rising fish during massive hatches. Book guides early. |
| Summer (Jun-Aug) | Potential water quality issues | 2022-2023 saw low dissolved oxygen. Fish early morning. Hot for anglers. |
| Fall (Sep-Oct) | Good fishing, moderate crowds | Brown Trout Bonanza tags worth $300. Pleasant weather. |

The Bigger Picture
Lee's Ferry exists as a trout fishery because of Glen Canyon Dam - the same dam that drowned Glen Canyon itself and fundamentally altered the Colorado River ecosystem. It's a complicated legacy.
The cold, clear water that makes trout thrive also disrupts native fish populations downstream. The brown trout bounty program exists because one introduced species threatens another. The fishery's recent decline is tied to broader water management decisions across the Colorado River basin - the same decisions affecting water supply for 40 million people in the Southwest.
None of this means you shouldn't fish here. But it's worth understanding what you're stepping into - a manufactured ecosystem in a landscape that's been shaped and reshaped by human infrastructure for decades. The fishing is good. The place is stunning. And the future is uncertain.
Bottom Line
Lee's Ferry is a technical tailwater fishery that rewards patience, precision, and realistic expectations. The glory days of 40-fish days with multiple 20+ inch rainbows are likely past - 2022 AGFD data shows the lowest catch rates in 31 years of monitoring. But quality fish remain for anglers willing to work for them.
What to expect today:
- 10-20 fish on a good day (with a guide)
- Average size 14-18 inches
- Occasional fish over 20 inches
- Technical fishing requiring small flies (#18-24) and light tippet (5X-6X)
- Stunning red rock canyon scenery you won't find anywhere else
Come with appropriate expectations, bring small flies and light tippet, and appreciate the surreal experience of trout fishing in the desert at the doorstep of the Grand Canyon. And if you catch a brown trout, turn it in for the bounty - you'll pocket some cash while helping protect native species that have called this canyon home far longer than any trout.
Frequently Asked Questions
When is the best time to fish Lee's Ferry?
Fall (October-November) and spring (March-May) offer the best fishing at Lee's Ferry, with cooler air temperatures and active midging. Summer brings steady fishing early and late in the day despite hot weather. Winter provides excellent midge fishing with fewer crowds, and water temperatures stay consistent year-round thanks to Glen Canyon Dam's deep-water releases.
Where should you fish at Lee's Ferry?
Most anglers focus on the first 4 miles below Glen Canyon Dam, accessible by boat or on foot from the Lee's Ferry launch ramp. The Paria Riffle near the boat ramp is the easiest wade fishing access. For boat anglers, the stretch from the dam to Cathedral Wash offers the best concentration of fish along current seams and near-shore structure.
What flies work best at Lee's Ferry?
Small midges (#18-24) produce year-round at Lee's Ferry, with San Juan Worms, scuds (#14-18), and egg patterns as consistent subsurface options. Match the hatch with midge clusters and emergers during morning and evening activity. Bring 5X-6X fluorocarbon tippet — the clear water demands light leaders.
