358-acre lake in Nipissing District, Ontario. The lake tops out around 26 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. What the data behind the map says about each species, season by season:
Drawn out, this is 357 acres of water rimmed by 6.4 miles of bank — one island included. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 1.3 mi of water from one end to the other, 1.1 mi at the beam. The water lies in Nipissing District. The nearest mapped water is South Spruce Lake, 1 mi to the north.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 8 to 26 ft. Put Deep basin first on the milk run — a deep basin near 20 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 | Back-bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 26 ft, and winter fish settle into 8 to 26 ft. Break off the point is the standout, a drop-off at roughly 4 ft, rated prime for winter smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 8 to 26 ft | dawn & dusk | Break off the point (4 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (4 ft) | Jerkbait, Blade bait |
| Winter | 8 to 26 ft | midday | Break off the point (4 ft) | Blade bait, Hair jig |
