2023 September Fly-Fishing on Owyhee River

Embracing the September Spirit:

September is a magical time on the Owyhee River, where the transition from summer to fall is palpable. Cooler temperatures and changing foliage create a picturesque backdrop for anglers eager to indulge in their passion amidst nature's seasonal shift. With school back in session and fewer crowds, September offers a quieter and more intimate experience on the river.

Notable Hatches and Fly Patterns:

  1. Blue-Winged Olives (BWOs): These small mayflies often make their appearance during overcast days. Patterns like the Parachute Adams, RS2, and Sparkle Dun in appropriate sizes can mimic BWOs effectively.

  2. Mahogany Duns: Another mayfly hatch that can occur in September. Utilize patterns like the Parachute Hare's Ear and Mahogany Dun to match their profile.

  3. Hoppers: Late summer into early fall is prime hopper season. Big foam patterns like the Dave's Hopper and Morrish Hopper can entice trout looking for a substantial meal.

Strategies and Techniques:

  1. Dry Fly Magic: The BWO and Mahogany Dun hatches can lead to exciting dry fly action. Cast delicately and present your flies accurately to rising trout.

  2. Terrestrial Play: Hopper patterns imitate grasshoppers and other terrestrial insects that may fall into the water. Experiment with different sizes and colors to discover what piques the trout's interest.

  3. Nymphing Opportunities: Despite the dry fly potential, nymphing can still be effective. Focus on deeper runs and pools with nymph patterns like Pheasant Tails, Hare's Ears, and Zebra Midges.

Adapting to Autumn Conditions:

  1. Layer Up: As temperatures start to drop, layering your clothing is essential. Pack a light jacket or fleece to stay comfortable throughout the day.

  2. Mind the Light: September days might be shorter, so plan your fishing accordingly. Consider fishing earlier in the morning and later in the afternoon to make the most of the available light.

  3. Approach with Care: With potentially clearer water and spookier trout, maintain a low profile and exercise caution when approaching the water's edge.

Conservation Ethos:

In this delicate time of seasonal change, it's important to approach the river with conservation in mind. Follow catch-and-release practices and adhere to Leave No Trace principles to ensure the Owyhee River remains pristine for future generations of anglers.
