Lake Trout FAQ

Answers from onWater's species guide.

What flies work for Lake Trout in California?

Large streamers and flies are essential - tie patterns 6-10 inches long using synthetic materials like Slinky Flash, with articulated Double Deceivers being particularly effective. Clouser Minnows and Half-and-Half patterns in 5-6 inch lengths with orange saddle hackles work well.

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

Spring and fall offer the best opportunities when Lake Trout move to more accessible depths, while summer fishing requires deeper presentations in the thermocline.

How do you catch Lake Trout in California?

Vertical jigging is highly effective - drop jigs to depths where fish are marked and use rod movements to create attractive action. Trolling with downriggers and leadcore lines works well in deeper waters.

What do Lake Trout eat?

They are top predators in deep lake ecosystems, feeding primarily on fish including sculpins, chubs, minnows, and other trout. Young Lake Trout eat plankton, insects and small invertebrates, while adults prefer fish.
