Kirman Lake - Mono County, CA

Kirman Lake is a remote, high-elevation stillwater fishery in Mono County, CA, best known for its trophy brook trout and Lahontan cutthroat. Accessible only via a 3-mile hike or bike ride from Highway 108 near Sonora Pass, Kirman provides solitude, beautiful scenery, and the chance to hook unusually large trout in a wild setting.

Covering roughly 50 acres, the lake is nutrient-rich and features ample aquatic vegetation, supporting strong populations of midges, damselflies, and callibaetis. Balanced leeches, chironomids, and damsel nymphs fished under indicators are the most productive flies. Anglers may also find limited dry fly opportunities during calm, warm periods when callibaetis or terrestrials are active.

The lake opens after snowmelt, typically in late May or early June. Peak fishing occurs through July and again in September and October. Float tubes or pontoons are helpful for reaching deeper weed lines, though some shoreline areas are fishable on foot.

Kirman is a special-regulation fishery that emphasizes conservation and quality over quantity. Historically famous for giant brook trout, it now supports robust populations of Lahontan cutthroat as well. These fish are aggressive and strong, offering excellent fights on 4–6 weight rods.

With no motorized access, light fishing pressure, and exceptional trophy potential, Kirman Lake is a rare and rewarding destination for adventurous fly anglers seeking backcountry stillwater trout in California’s Eastern Sierra.
