Reach in the air, drift drag-free. The upstream belly feeds the fast tongue instead of the fly — buying the dead-drift feet that earn the take.
Line management
The reach cast and the upstream mend
What it's for
Between you and a rising fish runs a faster tongue of current. Cast straight across it and the belly of your line is snatched downstream, dragging the fly off its lane before it ever reaches the fish. The reach puts an upstream curve into the line while it's still in the air; the mend restores that curve once it's down.
The beats
Read the lane
Find the fish's feeding lane, and find the faster water between you and it. That intervening tongue is what will drag your fly.
Reach in the air
Make the forward cast, then — before the line lands — sweep the rod upstream. The line falls with its belly already curved up-current of the fly. The reach is an aerial mend, not an afterthought.
Drag-free drift
The fast tongue spends its pull straightening the upstream belly instead of dragging the fly. The fly tracks straight down its lane at the water's own pace.
Take and lift
Follow the fly down with the rod tip. As the belly runs out and drag is about to set in, lift off — smoothly, because that lift is sometimes the take.
Common faults
Straight cast, late mend
The fly skates across its lane throwing a little wake; the fish drops back and refuses.
Fix: Put the curve in before the line lands — reach while the cast is in the air. A mend flipped after drag has begun is a fix for the next cast, not this one.
When you'll use it
- A rising fish on the far seam with faster water between you and it
- Any upstream dry-fly presentation across conflicting limestone currents
- Long drifts where the belly would otherwise be grabbed and drag the fly
