HOPPER-DROPPER MONO-LOOP SYSTEM

I first read about the hopper-dropper mono-loop system in a Fly Fusion Magazine Article “Overlooked Abundance: Terrestrials through the Season” by Ryan Sparks, although Sparks credits the invention of the system to a California angler named Mikey Wier. This mono-loop system is used when nymphing with a dry fly attractor, or hopper-dropper nymphing rig. I will walk you through how to tie and fish the hopper-dropper mono-loop system below.

First off, a dry fly attractor nymphing rig is when you use a buoyant dry fly, such as a grasshopper, and tie a nymph to the shank of the dry fly’s hook – the dropper fly. This combo can be incredibly effective because you can fish two different levels of the water column, two different bug species, or two different insect life stages at once. However, the biggest drawback to this system is that the length between your dry fly and nymph is constant. Meaning, you have to cut your dropper line section or retie a new section on in order to adjust the distance between the two flies. However, the mono-loop system solves this problem because it makes the system adjustable.

To tie the mono-loop system, tie a nymph to the end of your leader just as you would if you were straight nymphing or dry fly fishing (A). Then use monofilament line to tie a loop tag into the eye of your hopper; this mono section should be about two inches long (B). Monofilament is more buoyant than fluorocarbon, so it is preferable over fluorocarbon because you want your hopper fly to float. After you tie a loop tag to your hopper, attach it to your leader by placing the loop under your leader, and the butt end of your fly through the loop (B). To adjust the hopper, just loosen the loop and slide it up or down your leader (C).

  1. Good anglers understand that consistently meeting the fish with a nymph on the bottom of the river (or elsewhere in the water column), requires frequent adjustments for depth.
