Shasta Lake Fishing
Adding to the native stock of Rainbow trout, California Fish and Game began stocking Shasta lake with game fish to offer a wide variety of options. Trout: Rainbow, Brown and Kamloops; Bass: Largemouth, Smallmouth, and Spotted; Catfish: Channel and Bullhead. The lake also has Sturgeon and land-locked King Salmon.
During the summer months, Shasta is the hottest bass fishing lake in the State. Anglers can practice an array of fishing strategies as they fish for Florida-hybrid Largemouth bass, Smallmouth bass, and Spotted bass.
A lake favorite, German Brown trout are marauders that stay deep in the bowels of Shasta Lake during the warmer months of the year. In the cooler months they come up close to the banks and are very aggressive. They are mainly caught in the winter when they will hunt and eat almost anything. Large lures are pulled very quickly along the banks to catch them. They can also be caught on flies, glo-bugs, hard plastics, spinners and crank baits. Brown Trout are tough fighters and do not tire easily. Specimens have been caught up to 38 lbs.
Though not many anglers fish for sturgeon, the lake record is a 190-pound behemoth boated in 1977 that measured 8 feet, 2 inches.
