Rating depth structure for rainbow trout.

44-acre lake in British Columbia. The lake tops out around 16 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What the data behind the map says about each species, season by season:
Traced from the shoreline, Summit Lake runs 44 acres with 1.4 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. 81% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.7 mi of water from one end to the other, 0.2 mi at the beam. The water lies in East Kootenay Regional District. The nearest mapped water is Crowsnest Lake, 3 mi to the east.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. Summer is a 5 to 16 ft game here, winter a 4 to 16 ft one. Start at Break off the point. It's a drop-off holding about 7 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.
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 | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 5 to 16 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (7 ft) | Trolled spoon (small), Inline spinner |
| Fall | 3 to 16 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 4 to 16 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (7 ft) | Small jigging spoon, Marabou jig |
In spring, rainbow trout run shallow here, mostly 4 to 16 ft. Summer keeps them at 4 to 16 ft, and they winter in 3 to 16 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 7 ft. 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 | 4 to 16 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 16 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 16 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 16 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |

Summit Lake is about 16 ft (5 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target cutthroat trout, rainbow trout on Summit Lake.
Break off the point is the top-rated area: a drop-off in about 7 ft of water that rates prime for cutthroat trout in summer. The map above holds the full rated-spot list for every species and season.
For cutthroat trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
