Golden Trout


Golden Trout

California Golden Trout (Oncorhynchus mykiss aguabonita) is California's official state freshwater fish since 1947 and one of the most beautiful trout species in the world.

Scientific Name: Oncorhynchus mykiss aguabonita


Physical Characteristics:
  • These stunning fish are characterized by their brilliant golden-yellow sides, brassy or olive-green backs, and distinctive crimson stripe running laterally from the gill covers to the anal fin.
  • Adults typically display about 10 dark parr marks along the lateral line and have white-tipped fins with black bands.
  • In their native streams, they rarely exceed 6-12 inches, though lake-dwelling populations can grow larger.

What to know

Habitat Distribution

  • Native to just two high-elevation watersheds in the southern Sierra Nevada Mountains - Golden Trout Creek and the South Fork Kern River in Tulare County.

Key Locations

  • Golden Trout Creek (designated Heritage Trout Waters), South Fork Kern River (Wild Trout Waters), Cottonwood Lakes, Mulkey Creek, and various high-alpine lakes in the Sierra Nevada.

Specific Spots

  • They prefer slow-moving, meandering streams with sand or gravel bottoms, seeking pools and undercut banks.
  • Most productive waters are above 10,000 feet.

Golden Trout FAQ

Answers from onWater's species guide.

What are the best lures and bait for Golden Trout in California?

Small lures can be effective, though casting can be challenging in smaller tributaries with riparian vegetation.

What flies work for Golden Trout in California?

Golden Trout readily take dry flies and terrestrials, with caddis patterns, midges, and terrestrial imitations being particularly effective. Small fly patterns work best since these trout feed primarily on small aquatic insects. In lakes, they respond well to midge pupae patterns, especially chironomid imitations.

When is the best time to fish for Golden Trout in California?

Summer and fall months when these fish are most active, typically July through October after spawning concludes. During spawning season (late May-June), anglers should avoid targeting these fish to protect the vulnerable population.

How do you catch Golden Trout in California?

Fish the deeper pools and undercut banks where Golden Trout typically hold. In the Cottonwood Lakes basin, focus on the creek connections between lakes and the inlets from higher lakes. Catch-and-release practices help preserve this critically threatened subspecies.

What do Golden Trout eat?

Golden Trout primarily feed on aquatic insects, especially dipteran midges and caddisflies, as well as terrestrial insects. They also consume zooplankton like Daphnia and occasionally small crustaceans.
