14-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 16 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 14 acres of water rimmed by 0.7 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 71% of the surface on the model — that's where the groceries are. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. The water lies in Northumberland County. Closest neighbour on DepthScout: McKendrick Lake, 1 mi northwest of here.
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 16.1 ft, and winter fish settle into 5 to 16.1 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall 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 (8 ft) | Ned rig, Tube jig |
| Summer | 5 to 16.1 ft | dawn & dusk | Break off the point (7 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 16.1 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 5 to 16.1 ft | midday | Break off the point (7 ft) | Blade bait, Hair jig |
Spring chain pickerel on Rocky Brook Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 3 to 15 ft, and by winter most fish are in 4 to 16.1 ft. The chart's best answer is Break off the point — drop-off, 7 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a weedless spoon + trailer or a buzzbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Break off the point (7 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Break off the point (7 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 4 to 16.1 ft | dawn | Break off the point (7 ft) | Jigging spoon (through ice) |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 16.1 ft, then a winter hold in 5 to 16.1 ft. Put Deep basin first on the milk run — a deep basin near 14 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 | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16.1 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16.1 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16.1 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 5 to 16.1 ft before dropping to 2 to 16.1 ft for winter. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 16.1 ft | dawn & dusk | Deep basin (14 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 16.1 ft | dawn | Deep basin (14 ft) | Small jigging spoon, Tungsten jig + plastic |
