192-acre lake in Cochrane District, Ontario. The lake tops out around 23 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What the data behind the map says about each species, season by season:
On the chart, Little Agassiz Lake draws 191 acres inside 2.8 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 79% of the surface on the model — that's where the groceries are. Figure 0.9 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Cochrane District. The nearest mapped water is West Trappers Lake, 6 mi to the west.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 7 to 23 ft game here, winter a 7 to 23 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 23 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 23 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 23 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
