Understanding the Hatches on the Jefferson River
The hatches on the Jefferson River are a fly fisher’s dream. These insect events are what drive trout feeding behavior and create incredible opportunities for anglers. Here are the key hatches you’ll encounter:
- Skwalas
- Caddis
- PMDs (Pale Morning Duns)
- Crawfish
- Baetis (Blue Winged Olives)
- Terrestrials
Now, let’s break down these hatches and the best ways to fish them.
Skwalas
Timing and Behavior
The Skwala hatch kicks off early in the season, typically in early spring. These stoneflies are best found on rocky river bottoms where trout lie in wait. The Skwala hatch isn’t a big hatch but trout are looking for them, despite the lack of large numbers of naturals.
Fishing Tips
- Rig Setup: Large, dark stonefly nymphs or dry Skwala patterns are incredibly effective.
- Where to Focus: Search for areas with rocky bottoms and moderate flows. Target drop-offs and deep runs for the best results.
- Bonus Tip: Use a nymph rig before the hatch, then switch to dry flies as soon as you notice surface activity.
Suggested Patterns:
- Skwala Stonefly
- Pat’s Rubber Legs
- Chubby Chernobyl’s
Caddis Hatch
Timing and Behavior
Caddisflies are prolific on the Jefferson River, especially during late spring and early summer. They thrive in riffles and moderately fast water. You’ll often find trout feeding aggressively during an evening caddis hatch.
Fishing Tips
- Rig Setup: Dry-dropper rigs are a great choice. Pair a caddis dry fly with a caddis pupae pattern as your dropper.
- Where to Focus: Place your casts in riffles and faster-moving water, where trout are actively rising.
- Bonus Tip: During heavy hatches, try “skating” your dry fly by pulling it across the surface to mimic an emerging caddis’s movement.
Suggested Patterns:
- Elk Hair Caddis (Tan or Olive) sizes # 14-18
- Goddard Caddis (Natural) sizes #14-18
- X-Caddis (Tan or Olive) sizes #14-18
- Caddis Pupae (Green or Brown) sizes # 14-18
PMDs Pale Morning Duns
Timing and Behavior
PMDs are one of the most underrated hatches on the Jefferson. They typically show up in late early summer and linger through July peaking during the late morning to early afternoon.
Fishing Tips
- Rig Setup: Use long, light leaders paired with small parachute PMD patterns for the best presentation.
- Where to Focus: Trout often target PMDs in slower currents and tailouts. Approach these areas gently to avoid spooking the fish.
- Bonus Tip: Watch for emerging PMDs on cloudy days when hatch activity increases significantly.
Suggested Patterns:
- Parachute PMD
- Sparkle Dun PMD
- PMD Emergers

Crawfish
Timing and behavior
Crawfish become the main food forage for the trout of The Jefferson in mid-summer as the water temperatures rise.
- Rig Setup: Use a short leash set-up for your nymphing. Heavy leaders paired with small crawfish patterns for the most natural presentation.
- Where to Focus: Trout will target crawfish in fast currents and deep buckets.
- Bonus Tip: Use a downstream mend to intentionally make your fly jump after it’s reached depth. This mimics the swimming action of a crawfish and increases strikes significantly.
Suggested Patterns:
- Beadhead rubber leg crystal bugger
- Fighting Crawdad
- Son of Crazy Dad

Baetis (Blue Winged Olives)
Timing and Behavior
Baetis hatches are a favorite for anglers. These insects tend to hatch during overcast and rainy conditions, beginning in early spring and extending into fall.
Fishing Tips
- Rig Setup: Fish emerger patterns just below the surface for a natural presentation.
- Where to Focus: Concentrate on areas with gentle currents and soft seams, as trout often gather here to feed on Baetis.
- Bonus Tip: Present your fly softly to avoid alarming trout in low-light conditions.
Suggested Patterns:
- Baetis Emerger
- CDC Comparadun
- RS2 (Olive or Gray)
Terrestrials
Timing and Behavior
Terrestrials, such as grasshoppers and ants, dominate the trout’s diet in mid to late summer. Trout often line up along grassy banks, waiting for unlucky insects to fall into the water.

Fishing Tips
- Rig Setup: Use hopper and ant patterns. Add some twitching action to your hopper to mimic natural movement.
- Where to Focus: Cast close to grassy banks, undercut banks, or other vegetation-rich areas.
- Bonus Tip: Don’t overlook windy afternoons. Wind helps blow terrestrials into the river and gets the trout feeding.
Suggested Patterns:
- Foam Hoppers
- Parachute Ants
- Chubby Chernobyl
