The Deadly Duo – Water Boatmen & Back Swimmers

Stillwater Edge Podcast - Episode #25: The Deadly Duo – Water Boatmen & Back Swimmers

Hook: If you’re not fishing water boatmen and back swimmers, you’re missing out on some of the most explosive takes in Stillwater fishing. These overlooked insects are a powerhouse food source for trout, and when they’re on the menu, the action is unforgettable. In this episode, I’m breaking down why fish love them, how to imitate them, and the best ways to fish them effectively.

Key Takeaways from This Episode

What Are Water Boatmen & Back Swimmers?

• Water Boatmen: Bottom dwellers that primarily feed on plant matter.
• Back Swimmers: Predators that hunt other insects, moving with a distinct pulsing motion.
• Both are fast, zippy swimmers that trout can’t resist.

Why Should You Fish Them?

1. High Protein & Energy-Rich: Trout love them for their high caloric value.
2. Peak Seasonal Activity: Especially effective in spring and fall during migrations and mating periods.
3. Explosive Strikes: Their movement triggers aggressive trout reactions, making for some of the most exciting fishing moments.

How to Fish Them for Maximum Success

1. Floating Line Method (Best for active presentations)

• Use a floating line with a 6-8 foot leader.
• Fish shallow water and the littoral zone where these insects live.
• Use a slow hand-twist retrieve OR short, quick strips with a pause to mimic their movement.
• Pro Tip: The key trigger is the "dive and rise" motion—strip to make the fly dart down, then let it rise slowly.

2. Indicator Method (For when casting distance is limited)

• Suspend the fly 18 inches under an indicator.
• Fish it in shallow zones and let the natural motion of the water create movement.
• Occasionally give it small tugs or pulls to mimic the natural erratic movement of boatmen.
• Great option for kids or beginners who struggle with retrieving.

When to Fish Water Boatmen & Back Swimmers

• Spring & Fall: Migrations and mating activity make them a prime trout food source.
• Late Afternoons: After a chronomid hatch dies down, boatmen hatches often kick off.
• Overcast Days: Trout move into shallow water, where boatmen are active, making it a prime time to fish them.

Final Thoughts

Boatmen and back swimmers might not get the same hype as leeches or chronomids, but they should absolutely be in your Stillwater fly box. Next time you're on the water, tie one on and get ready for some aggressive trout action.
