Rating depth structure for rainbow trout.

72-acre lake near Cole Bay. The lake tops out around 33 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 72 acres wrapped in 2 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. About 55% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.6 mi end to end and 0.4 mi across at its widest. It sits in Division No. 18. Its nearest charted neighbour, Fern Lake, is 1 mi to the southeast.
Spring brook trout on Atchison Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Deep basin — deep basin, 28 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (28 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 7 to 33 ft. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 33 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 33 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
