62-acre lake in Cochrane District, Ontario. The lake tops out around 44 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Heart Lake maps at 61 acres behind 1.8 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. 64% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. It sits in Cochrane District. Its nearest charted neighbour, Centre Triple Lake, is 1 mi to the northwest.
When the water first warms, brook trout slide up into 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. If you only fish one area, make it Break off the point: a drop-off around 20 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring splake on Heart Lake hold shallow, usually 5 to 25 ft. By summer they slide out to 13 to 44 ft, and by winter most fish are in 10 to 44 ft. The chart's best answer is Break off the point — drop-off, 20 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a trolled spoon at the thermocline or a white tube jig (deep).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
