13-acre lake in Cochrane District, Ontario. The lake tops out around 36 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:
The outline encloses 12 acres, worked by 0.5 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. 22% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Cochrane District claims this one. If the bite dies, Driscoll Lake is 0 mi to the east.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Shoreline break: a drop-off around 16 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (16 ft) | Small jigging spoon, Tungsten jig + plastic |
