Lost Lake, Montana: Fishing Spots and Seasons

• Overview

  Lost Lake stands in Flathead County, Montana. The country here is mixed forest. About 16 acres of surface, which puts the far bank inside easy sight. Libby sits 32 miles from here and is the nearest stop. Thompson Falls follows at 35 miles, then Kalispell at 35 miles. This one sits near enough to a boundary to be worth checking.

• Where to Fish on Lost Lake

  Depth remains unrecorded, so treat the first session as a survey. Read the surface for the wind lane, then fish the edge of it. Where the bottom changes texture, fish gather; find that line. Across Flathead County, recorded fish include rainbow trout, sockeye salmon, largemouth bass, brook trout and yellow perch. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. On Lost Lake that means starting tight and working out.

• Seasonal Patterns

  Climate records put August near 62°F and January near 22°F. Cold locks it up for a good stretch each year. Firm cover through the cold months, then open water from early April. On the long-run averages the water opens up around early April and starts locking again about late November. Right after break-up, and again as the nights sharpen, is when to go. Keep it in mind when planning a trip to Lost Lake.

• Tackle & Baits

  Access is not recorded for this water. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Local rules can differ across the county line, so check where you stand. Where tickets apply, they are sold in the nearest town rather than on the bank. The nearest alternative is Middle Thompson Lake, 2.4 miles out. Nothing here settles the position at Lost Lake for certain.
