58-acre lake in Cochrane District, Ontario. The lake tops out around 105 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. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 58 acres, worked by 1.4 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 29% of this chart, as modeled. End to end it runs roughly 0.5 mi, about 0.3 mi across. Cochrane District claims this one. Park Lake sits 0 mi west — the closest neighbouring chart.
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 Shallow bay flat: a weed flat around 6 ft that scores good in spring. 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 (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | 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 | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Blue Lake hold shallow, usually 10 to 40 ft. They move out to 32 to 105 ft in summer and finish the year down in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 89 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
