14-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 16 ft. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled. 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. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. 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 ft, and winter fish settle into 5 to 16 ft. Deep basin is the standout, a deep basin at roughly 16 ft, rated good 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 5 to 16 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 16 ft chart-limited; documented 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 5 to 16 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (16 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 ft. The chart's best answer is Deep basin — deep basin, 16 ft, good for winter. 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 | open water | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | open water | Jerkbait along weed edges, Spinnerbait |
| Winter | 4 to 16 ft chart-limited; documented 5 to 18 ft | dawn | Deep basin (16 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 ft, then a winter hold in 5 to 16 ft. Put Deep basin first on the milk run — a deep basin near 16 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 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (16 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 ft before dropping to 2 to 16 ft for winter. The spot to know is Deep basin, a deep basin in about 16 ft of water that rates good 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.

Rocky Brook Lake is about 16 ft (5 m) deep at its deepest point. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout on Rocky Brook Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Deep basin is the top-rated area: a deep basin in about 16 ft of water that rates prime for yellow perch in fall. Every other rated spot, per species and season, is on the map above.
For smallmouth bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
