Green River Brown Trout Fall Flies

MATCH THE HATCH & MORE…

Fishing techniques on the Green River below Flaming Gorge Dam can vary depending on the specific insect hatch.

Here are some effective techniques for the key hatches:

### Midges

– **Techniques**:

Nymphing is highly effective. Use a double nymph rig with a Zebra Midge as the dropper fly. Dry fly fishing can also be productive during midge hatches, especially in the early morning or late afternoon.

– **Patterns**:

Zebra Midge (#18-22), Griffith’s Gnat (#20-24).

### Blue-Winged Olives (BWOs)

– **Techniques**:

Dry fly fishing is excellent during BWO hatches. Look for rising fish in slower water and back eddies. Nymphing with BWO nymphs can also be productive before the hatch.

– **Patterns**:

BWO Emerger (#18-20), Parachute Adams (#18-20).

### Caddisflies

– **Techniques**:

Swinging wet flies or skating dry flies can be very effective. In the evening, try using caddis dry flies near the banks and riffles.

– **Patterns**:

Elk Hair Caddis (#18-22), LaFontaine’s Sparkle Pupa (#14-16).

### Pale Morning Duns (PMDs)

– **Techniques**:

Dry fly fishing is the go-to method during PMD hatches. Target slower runs and back eddies where fish are rising. Nymphing with PMD nymphs can be effective before the hatch.

– **Patterns**:

PMD Nymph (#16-18), PMD Sparkle Dun (#16-18).

### Stoneflies

– **Techniques**:

Nymphing with large stonefly nymphs is very effective. During the hatch, try using large dry flies near the banks and in fast water.

– **Patterns**:

Golden Stonefly Nymph (#6-10), Stimulator (#6-10).

### Tricos (#20-22)

– **Techniques**: Dry fly fishing with Trico spinners is effective during the morning hatch. Look for fish sipping in slow, flat water.

– **Patterns**:

Trico Spinner (#20-22), Trico Parachute (#20-22).

Cicadas (SPRING & SUMMER 20-2025)

– **Techniques**:

Dry fly fishing with large cicada patterns can be very exciting. Cast near the banks and overhanging vegetation where cicadas are likely to fall into the water.

– **Patterns**:

Chris’s Chernobyl (#6-10), Fat Albert (#6-10).

General Tips

– **Nymphing**:

Use a strike indicator and adjust the depth to keep your nymphs near the bottom. A double nymph rig with a heavier fly on top and a smaller fly on the bottom can be very effective.

– **Dry Fly Fishing**:

Match the hatch by observing the insects on the water and selecting a fly that closely resembles them. Present your fly with a drag-free drift.

– **Streamers**:

When hatches are sparse, fishing with streamers can be productive. Use a sink-tip line to get your fly down to the fish.

These techniques should help you make the most of the diverse hatches on the Green River.
