Leslie Lake Fishing in Jefferson County, Montana

• Overview

  Leslie Lake is listed under Jefferson County, Montana. The surface lies 8,150 feet up. About 5 acres of surface, which puts the far bank inside easy sight. It is one of the smaller waters we list in Jefferson County. Nearest town is Boulder, 12 miles off. Then Clancy, 13 miles, and Townsend, 18 miles. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Leslie Lake

  Depth is not on record here, which means reading the ground instead. Bays and points beat straight shoreline every time on water like this. On a natural lake the weed line and the shelf beyond it do the work. County-wide records name rainbow trout, brook trout, brown trout, cutthroat trout and longnose sucker. What holds for the county may not hold for this water. On Leslie Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  Between January at about 19°F and July at about 55°F, the water has a wide range to work through. Winter closes the water for a while, and the reopening is worth catching. The freeze runs deep into the year, with break-up near early May. From about early May to around mid November, expect open water on the long-run figures. May into June fishes hardest, and September gives a second good stretch before the lid returns. Expect Leslie Lake to follow that timing.

• Tackle & Baits

  We have no record of the rules that apply on this bank. Formal access is not mapped, so the last stretch is likely on foot. For the trout, small spinners and a box of nymphs cover both approaches. Where access is informal, keep it that way by behaving. Barbless rules turn up on managed water more often than not. If the gate is shut, Glenwood Lake at 1 mile is the nearest alternative. Confirm access to Leslie Lake locally before you travel.
