Key points
- Why it's tough: warm upper layers drive trout to cooler, oxygenated depths; most hatches (midge, mayfly, caddis, damsel, dragon) are over .
- Summer diet: shrimp/scuds, immature dragonfly nymphs, leeches, zooplankton (Daphnia/Cyclops) — imitate the big items: leeches & dragonfly nymphs on full-sink lines .
- Timing: shallows are too warm by day; fish feed once the sun is off the water — dawn and dusk .
- Go higher: higher-elevation lakes stay productive through the heat .
- "Muddy" trout: blue-green algae blooms taint flesh in warm low-elevation lakes until fall — a reason to fish (or keep fish from) higher lakes .
Open questions
- Best nearby high-elevation lakes for the trip window (cross-ref alpine waters).
Forage in play
