25-acre lake in Cochrane District, Ontario. The lake tops out around 33 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.
On the chart, Milligan Lake draws 24 acres inside 1.1 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 51% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.3 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Cochrane District. For a second option, Munro Lake lies 4 mi south.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 28 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| 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 | 10 to 30 ft | dawn & dusk | Deep basin (28 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 | Break off the point (15 ft) | Small jigging spoon, Tungsten jig + plastic |
