Sight fishing flips the equation. Instead of casting blind to where you think fish are, you spot the fish first, watch how it's behaving, then make a single targeted cast. Catch rate goes up; pressure-per-fish goes down; the day becomes a hunt instead of a guess.
What you need:
- Polarized sunglasses. Without them, you're looking at glare; with them, you see the bottom. Amber lenses for shaded water, copper for mixed light, gray for bright sun.
- A high vantage. Walk above the water. Stand on a bank or a boulder. Look down through the surface, not across it.
- Patience. A single fish takes 5 minutes to spot, 5 more to read its behavior. Rushing means you'll miss every fish you could have caught.
What to look for:
- The dark slash of a fish's silhouette against gravel.
- The white flash of a turning trout's belly.
- Nervous water — a small wake or surface bulge from a fish moving below.
- Shadows that don't match what's casting them.
Once you've spotted a fish, watch it. Actively feeding (small movements toward drifting food)? Holding still (resting)? Cruising slowly? Each tells you whether to cast and what to throw.
The cast: from a position where the leader lands ahead of the fish, not on top of it. Match the fly to whatever it's eating. One drift through the feeding lane is usually enough.
