Lake Isabella sits in the southern Sierra Nevada where the North and South Forks of the Kern River converge, and it gives anglers two distinct experiences within a short drive of each other. The reservoir itself, accessed at spots like Launch 19 Boating Site and Pioneer Point, holds largemouth and smallmouth bass, catfish, and crappie, with water levels that shift considerably between wet and dry years — worth checking before you load the boat. The river sections are a different game entirely. Old Isabella and the South Fork Rec Campground put you on moving water where the fishing is more technical and the setting is quieter than the main lake. The South Fork of the Kern has a reputation for smaller but feisty trout in the right conditions, and Old Isabella offers a stretch of the main Kern that fishes well in spring before flows get too heavy. Whether you're launching a boat at one of the designated ramps or wading a riffle near camp, the variety here means you're not locked into one approach. Crowds are manageable outside of summer holiday weekends, and the elevation keeps temperatures reasonable even in late spring.
The reservoir is known for largemouth and smallmouth bass, channel catfish, and crappie. Striped bass are also present and draw dedicated anglers, particularly in spring. The river sections near Old Isabella and South Fork Rec Campground are better bets if you're targeting trout.
Launch 19 Boating Site and Pioneer Point are your main entry points for fishing the reservoir, with Launch 19 offering boat ramp access and Pioneer Point providing good shoreline options. For river fishing, Old Isabella and South Fork Rec Campground put you directly on the Kern River and its South Fork, where bank access is straightforward from either location.

Yes, a valid California sport fishing license is required for anyone 16 or older. The South Fork of the Kern has specific regulations that can differ from the main lake, so check the current California Department of Fish and Wildlife regulations for Kern County before your trip rather than assuming standard statewide rules apply.
Early morning and the last two hours before sunset are consistently the most productive windows, especially for bass on the lake. On the river sections near Old Isabella and South Fork Rec Campground, cooler midday temperatures in spring can keep fish active longer than you'd expect in summer.
For the lake, a medium-action spinning or baitcasting rod with 10-15 lb line covers bass and catfish well. If you're heading to the river sections, a lighter 6-8 lb setup with small spinners or PowerBait works for trout near South Fork Rec Campground. Bring sunscreen regardless of season — the Isabella basin gets intense sun and there's limited shade at most access points.
