Where to Fish Twin Lakes


The Twin Lakes (Upper and Lower) are located in the Wisconsin Creek Drainage in the Tobacco Root Mountains. Upper Twin Lake is not much of a lake anymore, but Lower Twin Lake supports fish. The shoreline is fairly steep all around the lake with half the shoreline consisting of rocky slopes. There are some signs of human impact with the trail/4X4 road and an old mining claim but traffic is slow here.

Size: 2.4696 acres
Elevation: 9400.48 ft
Directions: From Highway 287, turn northeast on County Route 64. County Route 64 turns into USFS Road 157. From USFS Rd. 157 turn right on trail 6307. It is recommended to hike up trail 6307 as it is very dangerous even for a ATV/UTV.
Status of the Fishery: Lower Twin Lake is on a stocking rotation with Westslope Cutthroat trout but there may be some reproduction occurring in the lake. The fish ranged from 11 to 14 inches during Summer 2018 sampling.

FWP Region: Region 3 
County: Madison
Fishing District: Central
Type: MTNLAKE
Notes: The shoreline is steep so casting could be difficult although there are no trees around the lake. The south shore is vegetated which makes for easy maneuvering but the north shore is rocky and tricky to navigate. During sampling in 2018, many fish were seen rising and a few were tricked with a dry fly from shore.
