Jefferson River Fly Fishing in June

Montana Fly Fishing the Jefferson River in June

High country snowpack draining into the Jefferson basin muddies the river with an extended early summer deluge, spiking flows through early June. Yet this annual full flush while inconvenient proves essential, scouring silt and debris from critical spawning beds to bolster future trout numbers.

Expect clearing conditions and dropping water levels by mid-June. Floating the Jefferson River at this time can provide some of the best action of the year. High flows concentrate trout near the banks and are accessible with streamers and nymphs.

June Hatches

Hatches are sporadic and sparse throughout the Jefferson River. Brown Drakes, pale morning duns, and caddis hatch throughout June on the river. Slow-rising trout can be found on cloudy days and evenings, feeding along bank side current seams.

Bozeman Fly Fishing Guide Pro-Tip:

Dead drifting small to large streamer patterns like a Copper Zonker along soft seams found off of the riverbank is the best way to target trophy trout on the Jefferson River in JUne. Running a shorter leader of about 3-3.5ft of 10-12lb test will help you avoid snagging debris that builds up in post-runoff conditions.

Suggested Techniques

As the water starts to drop in early June, the keen trout angler will quickly turn to their sinking fly lines and streamers selection before heading out to fly fishing the Jefferson River. Large articulated patterns in White, Yellow, Black, or Olive fished tight to the bank consistently produce some big trout from the Jefferson River in June.

Nymph fishing with tandem rigs that include a Crayfish or Sculpin imitation followed by a generalist searching pattern as a dropper are standard Jeff setups. As the water drops and flows stabilize, twitching and “dragging” these rigs - rather than dead-drifting them – becomes increasingly effective.

Dry fly fishing is sporadic, but the patient angler can find opportunities to cast to slow-rising trout in back eddies and along current seams during hatches and mayfly spinner falls, especially late in the day.

A Jefferson River fly fising trip is not for everybody. June is the prime summer month to fish the Jefferson, but ideal conditions are short-lived and weather-dependent.

The experienced angler will appreciate the solitude and scenery, with the opportunity to find a few trophy-sized brown or rainbow trout. This is not always the best river for new or novice anglers expecting consistent action.

Our staff of Bozeman fly fishing guides are always up for a day trip to the Jefferson when conditions are good.
