26-acre lake in Cochrane District, Ontario. The lake tops out around 40 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Duff L. 2 runs 26 acres with 1.8 miles of edge. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 86% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. The water lies in Cochrane District. Closest neighbour on DepthScout: Duff L. 1, 1 mi north of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Deep basin first on the milk run — a deep basin near 40 ft that grades prime for fall. In summer the feeding windows fall in 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (1 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (40 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring northern pike. Time it for early morning and the evening. 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (1 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for brown bullhead in spring. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 10 to 25 ft | midday | Deep basin (40 ft) |
