Late fall brings a different rhythm to the Lower Deschutes River. As fall Chinook move onto spawning gravel, loose eggs and disturbed aquatic insects become an important food source for resident Redside rainbow trout. Our shop often calls this seasonal feeding opportunity the “egg hatch,” and we love to fish it because it is a trout's final big source of protein before winter.
On an episode of Fly Fishing Unfiltered, NWFFO outfitter David Golobay and guide Sean discuss how to recognize spawning habitat, find trout water downstream, and choose between nymphing and swinging flies. The starting point is simple: protect the salmon and their redds, then build your approach around the trout water you can fish without disturbing them.
When Is the Deschutes River "Egg Hatch"?
The fall Chinook spawning period generally puts the egg hatch on anglers’ radar in October and November. Trout feeding opportunities can extend into late fall, but timing varies with salmon activity, water temperature, and river conditions. Let what you see on the river guide your day rather than treating a calendar date as a guarantee.
Eggs are only part of the picture. Spawning activity also dislodges aquatic insects, giving trout a reason to hold in feeding lanes downstream of the gravel. A stonefly nymph paired with an egg pattern covers both food sources.
How to Recognize Salmon Redds
A redd is a salmon’s gravel spawning nest. Look for lighter, freshly disturbed patches of gravel, often with a shallow depression and a mound of displaced material nearby. Salmon holding over or digging in that gravel are a clear reason to give the area room.
- Clean gravel: Recently moved stones can stand out against the darker surrounding riverbed.
- Depressions and gravel mounds: These are signs of nest-building activity, not places to stand or run flies through.
- Gravel bars and riffle transitions: Scout these areas from the bank before deciding where to fish.
- Surface texture: Changes in the current can help you read the bottom, but surface chop alone does not confirm a redd.
Give Spawning Salmon Space
Never walk on redds or cast into active spawning areas. Avoid disturbed spawning gravel even when no salmon are visible. Fish from the bank where practical, and leave any spot you cannot reach or fish without crossing sensitive habitat.
Where to Find Trout During the Egg Hatch
Focus on deeper pockets, seams, and drop-offs downstream of spawning flats, where the current carries food into holding water. You do not need to put your flies among the salmon to reach feeding trout.
- Start from the bank. Read the water before stepping in. Bankside pockets can offer useful drifts without wading onto spawning gravel.
- Choose a clear drift lane. Look for downstream water that lets you present, swing, and retrieve your flies without passing through salmon or redds.
- Move if you keep contacting salmon. Repeated accidental hookups are a reason to change your position or leave the spot, not keep repeating the same drift.
Three Ways to Fish the Deschutes Egg Hatch
Choose the presentation that fits the holding water and keeps your flies away from spawning fish. Short, controlled drifts suit compact pockets; a longer seam may call for an indicator or a carefully placed swing.
| Tactic | Water to Look For | Why Use It |
|---|---|---|
| Tight-line nymphing | Compact downstream pockets and bankside seams | Close control over short drifts and changes in depth |
| Indicator nymphing | Deeper slots and longer seams away from spawning fish | A controlled dead drift through a longer feeding lane |
| Trout Spey or single-hand swinging | Open downstream runs with a clear swing path | Covers water with an active presentation |
Tight-Line Nymphing
A short-line presentation lets you guide a weighted nymph-and-egg rig through individual pockets. Keep excess line off conflicting currents and adjust your position, depth, and weight until the flies travel naturally through the holding water. A standard fly-line setup can work well for the bankside approach discussed in the episode; there is no need to make this a contest between conventional and Euro-nymphing systems.
Indicator Nymphing
An indicator is useful when a deeper slot or longer seam calls for an extended dead drift. Adjust the rig to the depth and current rather than adding weight automatically. Set up well away from spawning fish, and make sure the full drift and retrieve stay clear of them.
Trout Spey and Swinging Flies
For anglers who prefer fishing a moving fly, a Trout Spey rod or single-hand setup offers another approach. Look for open water downstream of spawning flats, with enough room to swing without sweeping through salmon. An egg-sucking sculpin or weighted egg pattern gives you a different presentation to try when the water suits it.
Egg Flies, Stonefly Nymphs, and Rigging
Your flies need to reach the trout’s feeding depth without turning the presentation into a bottom-dragging exercise. Start with a manageable rig and adjust it to the pocket in front of you.
A Practical Nymph-and-Egg Setup
- Egg Sucking Stonefly: A weighted stonefly pattern represents the larger insects disturbed by spawning activity while helping the rig reach depth.
- NWFFO hand tied Eethy Egg: The tungsten-beaded egg pattern discussed in the episode is an option for compact pockets where getting down promptly matters.
- Standard yarn egg: An unweighted egg may need added weight, depending on the depth and current. Use only what the drift requires.
Patterns to Swing
An Egg Sucking Sculpin, called the “Egg Caressing Sculpin” in the episode, combines a sculpin profile with an egg accent. A tungsten-beaded Eethy Egg is another pattern to experiment with on a controlled swing through suitable downstream water.
Deschutes Egg Hatch FAQs
Can you fish for trout near spawning salmon without disturbing them?
The responsible approach is to keep your boots, flies, and line clear of salmon and their redds. Choose downstream holding water you can fish without crossing spawning gravel or drifting through active fish. If that is not possible, move on.
Why use a tungsten-beaded egg fly?
A tungsten bead helps an egg pattern sink, which can be useful in short drifts through deeper pockets. It does not eliminate the need to adjust for depth and current, and a heavier fly is not always the better choice.
Do you need a Trout Spey rod?
No. You can nymph or swing with a suitable single hand trout rod. A Trout Spey setup is another option when the water and casting room favor a swung presentation.
