51-acre lake in Algoma District, Ontario. The lake tops out around 46 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. Species by species, here's what the data says the year looks like.
The drawn water covers 51 acres wrapped in 1.8 miles of bank. With a 1.8 development index there's bank structure worth casting at, in moderation. 45% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. It sits in Algoma District. If the bite dies, Castleman Lake is 0 mi to the southwest.
Spring brook trout on Strums Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 21 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (12 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (21 ft) | Small jigging spoon, Tungsten jig + plastic |
