Rating depth structure for rainbow trout.

34-acre lake in Algoma District, Ontario. The lake tops out around 22 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 33 acres of water rimmed by 1.5 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 90% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. The water lies in Algoma District. The nearest mapped water is Friday L., 1 mi to the southeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 19 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 22 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (19 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 | Deep basin (19 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 6 to 22 ft; cold water stacks them in 4 to 22 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
