13-acre lake near Sheridan Region. The lake tops out around 55 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 outline encloses 13 acres, worked by 0.6 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 15% of this chart, as modeled. It sits in Johnson County. Thayer Lake sits 1 mi southeast — the closest neighbouring chart.
The spring pattern is a shallow one: cutthroat trout in 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 25 ft of water that rates prime for cutthroat trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon (small) or an inline spinner gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (14 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (25 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (25 ft) | Small jigging spoon, Marabou jig |
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Break off the point. It's a drop-off holding about 25 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (14 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (14 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (25 ft) | Small jigging spoon, Tungsten jig + plastic |
