Twin Lakes (Mammoth)

Updated October 23, 2025

Lower Owens and Bishop Area—Some nice browns are biting on the river below Big Pine, and flows on the Lower Owens are dropping, giving anglers the ability to wade into areas not accessible from shore. The river is well stocked with DFW trout.  Smaller creeks flowing down from the Eastern Sierra are stocked and pools are holding bigger fish. All services in Bishop Creek Canyon are now closed, but waters are still open. Lakes here are at higher elevations, so be prepared for storm and heavy snow if you are in the area until season’s end on Nov. 15.

Rock Creek, Convict Lake, Crowley Lake and Mammoth Lakes—Services in Rock Creek Canyon now closed, but waters are open to fishing. Wild lakes beyond Mosquito Flats trailhead good now for some wild rainbows, browns and brookies and they are feeding aggressively. Be prepared for storms. Crowley Lake services close on Oct. 26, but the lake is still open to fishing. Perch have moves into shallow waters to feed. Mammoth Lakes waters still open to fishing, but campgrounds and services now closed. Lakes are well stocked and could produce some nice fish for late season anglers. Twin Lake holds some bigger browns that become very active now.
