South Twin Lake, near La Pine, Oregon, within the Deschutes National Forest, is a picturesque high-elevation lake celebrated for its consistent trout fishing. This lake offers reliable opportunities for rainbow and brook trout, both regularly stocked by the Oregon Department of Fish & Wildlife (ODFW), ensuring good action, including healthy holdover fish.

Fishing conditions are generally favorable for trout, particularly when the Cascade Lakes Highway opens access from late spring through fall. Good fishing is reported, often best from the lake's south side, especially in cooler water. Effective methods include bait fishing with PowerBait or worms, and spin fishing with small inline spinners or spoons. Fly anglers find success "hanging flies under an indicator," using nymphs, chironomids, and leeches fished deep.

Access to South Twin Lake is convenient via Forest Road 4260, with public campgrounds and boat launches available for various watercraft. Conservation efforts focus on maintaining healthy trout populations. Anglers must strictly adhere to all ODFW regulations, including bag limits and proper fish handling, to preserve this productive and beautiful Central Oregon lake. South Twin Lake offers a reliably rewarding trout fishing experience in a classic Cascade mountain setting.
