5-acre lake near Sheridan Region. The lake tops out around 18 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Trigger Lake runs 5 acres with 0.4 miles of edge. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. About 57% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The water lies in Johnson County. The nearest mapped water is Magdalene Lake, 0 mi to the southwest.
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Summer is a 5 to 18 ft game here, winter a 5 to 18 ft one. The chart's best answer is Break off the point — drop-off, 8 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon (small) or an inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 18 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Marabou jig |
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 3 to 18 ft. Top water on the chart: Deep basin, a deep basin in the 15 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| 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 |

The spring pattern is a shallow one: rainbow trout in 5 to 18 ft. The depth story barely changes: 5 to 18 ft through summer, 4 to 18 ft in winter. The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
