Freshwater · High summer only — alpine ice-out to first snows
Golden Trout
Oncorhynchus aguabonita
California's state freshwater fish and the crown jewel of the high country — golden trout glow crimson and gold in Sierra Nevada and Rocky Mountain alpine lakes you have to hike to reach.
Seasons · Peak
Identifying features
- The most vividly coloured trout in North America: a golden-yellow body with a broad crimson lateral band
- About ten dark parr marks stay visible along the lateral line even on adults
- White tips on the dorsal, pelvic and anal fins, edged with black — a golden trout signature
- Red-orange belly and gill covers; spots are few and mostly on the tail half of the body
- Look-alike: rainbow trout are silvery-pink with heavy black spotting everywhere; goldens are gold, with spots confined to the tail region
Habits
- California's state freshwater fish: native only to the Kern River headwaters of the Sierra Nevada
- Stocked into hundreds of high alpine lakes across the Rockies, where it colours wilderness trips gold
- Feeds on midges, scuds and terrestrial insects; rises freely on calm summer evenings
- A short-season fish: most of its waters are ice-free only from late June to September
Distribution
Where to find them
- The Kern River plateau and Cottonwood Lakes in California's Sierra Nevada
- The Wind River Range and Beartooth alpine lakes (Wyoming/Montana)
- High cirque lakes of Colorado and Utah reached only on foot
Where they live
How to catch them
Dry-fly fishing alpine lakes
Rig: 3-5 wt fly rod, long light leader, small dries
Bait/lure: Dry flies — midges, ants and small mayfly patterns
Key tip: Creep up on the shore and cast from a crouch — alpine goldens spook at a skyline shadow.
Ultralight spinning
Rig: Ultralight rod, 2-4 lb line, miniature hardware
Bait/lure: Tiny gold spinners and 1/16 oz spoons
Key tip: Work inlet streams and drop-offs at dawn, before the afternoon wind ruffles the lake.
Best baits & lures
Baseline setup
- Rod: Ultralight spinning rod or 3-5 wt fly rod
- Line: 2-6 lb mono or 4-5 wt fly line
- Terminal: Tiny spinners, small spoons, dry flies and nymphs
