28-acre lake in Nipissing District, Ontario. The lake tops out around 120 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, David Lake runs 28 acres with 1.3 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. The shallow band under 15 ft claims about 30% of the surface on the model — that's where the groceries are. Figure 0.5 mi of water from one end to the other. You'll find it in Nipissing District. The nearest mapped water is South Iron Lake, 2 mi to the east.
Early season rock bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 20 ft game here, winter a 12 to 30 ft one. The chart's best answer is Main-lake point — point, 30 ft, good for summer. Best bite is the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (30 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (54 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (102 ft) | Tungsten jig + plastic, Small spoon + spike |
The chart marks 5 structure features on David Lake; the deepest is Deep basin at about 102 ft.
