2,554-acre lake in Cochrane District, Ontario. The lake tops out around 13 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 2,551 acres wrapped in 11.3 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 4.6 mi end to end and 1.5 mi across at its widest. Cochrane District claims this one. Its nearest charted neighbour, 21G-15, L., is 5 mi to the southeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 4 to 13 ft, and winter fish settle into 4 to 13 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| 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 | 4 to 13 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 4 to 13 ft, then a winter hold in 4 to 13 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| 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 | 4 to 13 ft | dawn & dusk | Break off the point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
