Left: a showy splash — a small fish chasing escaping food. Right: barely-there sips — the heavier fish eating at leisure. Rank fish by rhythm, not noise.
On the left a small trout explodes at an escaping dun; on the right a big trout barely tilts to sip a flush spent fly. Small fish make the noise — the quiet sipper is usually the better one.
On the river
Splashy vs confident
A splashy rise means escaping food; a quiet rise means helpless food — neither tells you the size of the fish.
You'll see
Two rivers of difference in one pool: over there, showy splashes that turn heads; over here, barely-there sips against the far bank. And occasionally a fish jumping clear of the water altogether.
What it means
Rise noise scales with how fast the prey can escape. Splash = chase: hatching duns skittering off, egg-laying sedges, big terrestrials kicking. Quiet = helpless: spents, cripples, smuts. A fish coming up from depth also splashes purely from momentum — whatever it's eating. And a single jump means almost nothing; repeated jumping means skating insects.
Log it: this is what the session’s fish activitychip means by “steady” — telling the plan what you’re seeing sharpens what it hands back.

How to fish it
Sort the pool by noise
Splashy risers are chasing — they'll forgive movement and even want it (a twitched sedge). Quiet risers are inspecting — they need the flush fly and the perfect drift. Fish them as two different problems.
Don't rank fish by splash
The best fish in the pool is more often the quiet sipper under the far bank than the acrobat mid-stream. Small fish splash; big fish budget energy.
Ignore the oncer jump
One aerial clearance is fool's gold — not feeding, not targetable. Multiple fish jumping repeatedly = something skating (sedge, cranefly): put a waking fly through it.
When to strike
Quick — a beat, no more
Splashy take at a moving fly: keep contact, strike the weight — quick but not instant. Quiet take on a spent fly: the full wait — "LoughLogic, LoughLogic", then lift.
The strike clock →Easily misread
"Did you SEE that? Huge fish!"
The boat/beat descends on the splashiest riser; the quiet sipper feeding steadily 20 m away is ignored.
Instead: Splash correlates with eagerness and prey speed, not size. Momentum from a deep lie also fakes it. Rank fish by rhythm and position, never noise.
Casting at the jumper
Twenty minutes of drifts over a fish that jumped once and never showed again.
Instead: A single jump isn't a feeding station — move on. Repeated jumping by several fish is the exception: that's a skating-insect emergence, and a waking fly earns its keep.
When you'll see it
- Sedge evenings — splash at the skaters, sips at the spents, simultaneously
- Hatch peaks when duns are leaving the water fast
- Any pool where you're about to pick the wrong fish for the wrong reason
