Colorado River at Lees Ferry

The mechanism

Everything at Lees Ferry is decided about fifteen miles upstream, at Glen Canyon Dam. This reach has no snowmelt pulse and no summer warm-up of its own. Water comes out of Lake Powell from deep in the reservoir, so it arrives cold year-round — the measured monthly averages run from the upper 40s in February to the mid-50s by autumn — and the volume is set by two things that have nothing to do with fishing: how much water the Bureau of Reclamation owes Lake Mead this year, and how much electricity the Southwest wants this week. That is why the flow table looks upside down compared to a normal river. Releases climb in July and August for air conditioning, climb again in midwinter for heating, and back off in the spring and fall shoulder months. Low water here is a September thing, not a August-drought thing.

What that means standing in it: flow is the whole game, and flow is a schedule, not a season. At the low end of the band the gravel bars and shallow shoals along the edges are walkable and the fish are pushed into water you can reach and read. At July and January levels the same river is spread wide and deep, the bars you would have waded are under two feet of moving water, and you are fishing the same fish from farther away with less of them within reach. The other half of the mechanism is that Lake Powell has been sitting low, and the numbers show it — water leaving the dam is warmer late in the year than a classic deep-release tailwater used to be. That is good for fish activity in September and October. It is also the reason Arizona Game and Fish and the Park Service keep changing what they ask anglers to do about non-native fish moving through the dam, so check their current pages rather than an outfitter's blog.

On foot, or on a boat

Lees Ferry sits at Marble Canyon, Arizona, where the Paria River meets the Colorado, off US-89A. The fishable reach is the fifteen miles of river between Glen Canyon Dam and the Lees Ferry launch ramp. Below the ramp the river becomes Grand Canyon whitewater and is a permitted rafting trip, not a fishing option.

Drive times: Page, Arizona is about 45 minutes and has a small airport with limited commercial service. Flagstaff (FLG) is roughly two and a quarter hours. Las Vegas (LAS) is four and a half to five hours. Phoenix (PHX) is about five hours. Salt Lake City is around six. Most people fly into Las Vegas or Phoenix, rent a car, and stay either in Page or at one of the small lodges strung along US-89A near Marble Canyon and the Vermilion Cliffs.

There are exactly two ways to fish it. Walk-in: park at the Lees Ferry ramp and walk upstream on the old road and bank trail, which gives you something over a mile of shoreline, gravel shoals, and side channels, plus the riffle water near the Paria mouth. That costs you a Glen Canyon National Recreation Area entrance fee and an Arizona fishing licence and nothing else. Check current fee and licence prices with the National Park Service for Glen Canyon and with Arizona Game and Fish directly — both change, and both are cheap enough that they will not decide your trip.

Boat: the other fourteen miles are motor-boat water only, and that is where most of the river's gravel bars and drop-offs are. Either you bring a jet boat and trailer it to the ramp, or you hire a guide out of Marble Canyon or Page. A guided day is going to be the largest single line in your budget by a wide margin — plan on several hundred dollars for the boat, which two anglers can split, and get a current number from the outfitter when you call, because rates move every season. If you are coming from out of state for three or four days, the sane split is one or two guided days to learn where the fish hold at that week's flow, then walk-in days to work it yourself.

Rigging that works here

This is a midge river first and a scud river second. The food base in a cold, clear, rock-and-algae tailwater like this one is not diverse — it is enormous quantities of very small things. Chironomid midges in every stage, and freshwater shrimp (scuds) living in the green algae on the cobble. There is some blackfly and, in recent years, more caddis than there used to be, partly because Reclamation has experimented with steady weekend releases in summer specifically to let bugs lay eggs where the eggs will not dry out. Whether that program is running in the year you come, and how, is worth checking on the Bureau of Reclamation's Glen Canyon operations page rather than assuming.

So: two small nymphs under an indicator, fished on the shallow gravel shoals and along the edges where the fast water drops into a slot, is how most fish here get caught. Small means small — this is a place where going a size down solves more problems than changing the pattern. Add eggs to the rig in late winter and spring when the rainbows are on the gravel, and again in late fall when the browns are, because eggs in the drift are the one time these trout get a big easy calorie. Streamers are worth carrying if you are on a boat working the upper river for browns. Dry-fly fishing exists but you have to earn it: flat, slow edge water, low light, and clouds of midges on the surface, mostly in the cool months.

When to be standing in it

Two clocks run at once. The first is the dam's. Releases change through the day and the change takes hours to travel downstream, so the walk-in water near the ramp is running on a delay from what the dam did this morning. The practical version: put a stick at the waterline when you arrive and look at it every twenty minutes. A rising river shuts down the shoal you were wading and turns on the flooded edges behind it; a falling river does the reverse and concentrates fish into the slots. Neither is bad. Not noticing which one is happening is bad.

The second clock is light in a canyon with walls. The sun gets into the river late and leaves early, and the shaded hours on either end are when midges come off hardest. In the low-flow shoulder months, first light to mid-morning is often the best window of the day and you can be back at the truck for lunch. In July and August the middle of the day is genuinely unpleasant on the water even though the river itself is cold — there is no shade on the gravel bars and no breeze to speak of.

Hazards

The river rises on somebody else's schedule. People get stranded here every year by wading out to a gravel bar or an island on a falling river and then finding the channel behind them chest-deep and pushing when they turn around. Do not cross moving water to reach an island you cannot walk back from at a foot higher.

The water is cold in every month — upper 40s to mid 50s. That is not hypothermia-in-minutes cold, but it is cold enough that a swim in fifteen thousand cubic feet per second of current is a serious event, not an embarrassing one. Wear a belt on your waders and pick your footing rather than your ambition.

The cobble carries a slick green algae that is genuinely as bad as it looks. Studded boots and a staff, both.

July through September is monsoon season on the Colorado Plateau. A thunderstorm in the Paria drainage can dump mud into the river right at Lees Ferry, and because the Paria comes in at the ramp, it is the walk-in water that goes brown while the upper river stays clear. That is an argument for a boat in late summer and an argument against late summer generally.

There is little to no cell service in the canyon. Downstream of the ramp is Grand Canyon whitewater with no take-out for many miles, which is why anyone running their own boat here carries a second means of propulsion.

Can I fish Lees Ferry without hiring a boat?

Yes, and plenty of people do. The walk-in reach runs upstream from the Lees Ferry launch ramp on an old road and bank path, giving you better than a mile of shoreline with gravel shoals, side channels, and edge water. It gets fished hard because it is the only free access, so expect company on a weekend. It is enough water for a couple of good days if you slow down and work it properly.

Is there still a reward program for brown trout here?

Do not plan around one. There has been an incentive program at various points and it has been discontinued and revived, and there are guide pages online still advertising versions of it long after they ended. Check the current Arizona Game and Fish regulations and the Glen Canyon National Recreation Area page before you come, and follow whatever they say that week.

What licence and fees do I need?

An Arizona fishing licence and the Glen Canyon National Recreation Area entrance fee. Buy the licence online from Arizona Game and Fish, and confirm the park fee and any launch fee for a private boat with the National Park Service. Both agencies change their numbers and their tackle rules without much warning, so read them rather than a summary — including this one.

Is August really that much better than July?

By the score, yes, and the reason is flow: August releases run high but more steadily, while July is the peak. Both months are hot and both carry monsoon risk in the Paria. If summer is your only option, take August over July and take a boat over walking in.

Is this a good river for someone who has only fished a handful of times?

It is a good river to learn indicator nymphing on, because the water is clear, the wading in low-flow months is gentle by tailwater standards, and there are a lot of fish. It is a poor river to learn on if you insist on dry flies. Come in the fall shoulder months, take a guide day early rather than late, and accept that most of your fish will come on very small nymphs fished carefully.

How many days should I plan?

Three fishing days is the minimum that justifies the drive from Las Vegas or Phoenix. Four is better, because it gives you one day to lose to weather, muddy water off the Paria, or a release schedule that does something you did not expect.
