Rating depth structure for rainbow trout.

34-acre lake near Aitkin County. The lake tops out around 21 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Loon draws 34 acres inside 1.1 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. About 78% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Aitkin County. For a second option, Remote lies 1 mi west.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 6 to 21 ft; cold water stacks them in 3 to 20 ft. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | open water | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 21 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | open water | Small jigging spoon, Tungsten jig + plastic |
Spring puts splake in skinny water — 4 to 21 ft is the zone. Summer fish stay in 6 to 21 ft, and winter fish hold in 5 to 21 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 21 ft chart-limited; documented 5 to 25 ft | dawn & dusk | open water | Small casting spoon (gold/orange), Inline spinner |
| Summer | 6 to 21 ft chart-limited; documented 25 to 60 ft | dawn & dusk | open water | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 6 to 21 ft chart-limited; documented 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait |
| Winter | 5 to 21 ft chart-limited; documented 10 to 45 ft | dawn | open water | Jigging spoon tipped with minnow head, Small white tube |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 6 to 21 ft before dropping to 4 to 21 ft for winter. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | Inline spinner (silver), Small spoon |
| Summer | 6 to 21 ft chart-limited; documented 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 21 ft chart-limited; documented 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 21 ft chart-limited; documented 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
When the water first warms, brown trout slide up into 3 to 21 ft. There's no big seasonal slide here — summer means 6 to 21 ft, winter 3 to 21 ft. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
