Rating depth structure for rainbow trout.

115-acre lake near Sled Lake. The lake tops out around 60 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
On the chart, Shirley Lake draws 114 acres inside 2.2 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. About 40% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.9 mi long by 0.3 mi wide at the broadest reach. The water lies in Division No. 18. Closest neighbour on DepthScout: North Brother Lake, 9 mi southeast of here.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 27 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (15 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (27 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (27 ft) | Jigging spoon, Tube jig (white) |
