BirdTroutOpen the map Lost River fishing report
No USGS gauge on the Lost River reports water temperature, so this report is the hatch record and the classification rather than a live number. September is Blue-Winged Olive, Cranefly, Green Rock Worm / Green Weenie and Caterpillar in northern Wisconsin, across the state line — 15 insects are recorded as active.

No gauge on this river answered with a temperature when this page was built. That is a gap in the gauge network, not a judgement about the water.
