Lost Lake near Arnold: Fishing Spots, Seasons and Access

• Overview

  Lost Lake lies within the bounds of Saint Louis County, Minnesota. The setting is rolling bush on every side. It runs to roughly 39 acres — big enough to hold fish away from the bank, small enough to learn. About 0.9 miles of bank, so nothing stays unexplored for long. Arnold is the closest town at 16 miles. The nearest city of size is Thunder Bay, 156 miles away. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Lost Lake

  Nothing in our records gives a depth for this one. Weed, then depth: that is the order to fish a water of this kind. Look for the band where the shallows give up and the bottom falls away. Fish documented in Saint Louis County include yellow perch, northern pike, white sucker, rainbow trout and walleye. These are county-wide records, so not all of them will be in this water. Lost Lake repays a walk before the first cast.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 65°F, while January sits near 6°F. Cold locks it up for a good stretch each year. The lid arrives early and lasts until roughly late April. Break-up sits around late April on average, with the water closing again about late November. The strong weeks are the first after break-up and the last before the freeze. It sets the rhythm of the year at Lost Lake.

• Tackle & Baits

  Whether the bank is open is not something our records settle. No dam controls it, and the level follows the season. Nothing built is recorded close to the bank here. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A landowner's word beats anything printed elsewhere. Rules for boats are stricter than rules for the bank in many places. If the gate is shut, Lieuna Lake at 1.7 miles is the nearest alternative. Nothing on Lost Lake should be assumed from this page alone.
