29-acre lake near Paroisse d'Addington. Government of New Brunswick lake depth survey. The lake tops out around 50 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Hartts Lake runs 29 acres with 1.2 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 71% of this chart. End to end it runs roughly 0.3 mi, about 0.3 mi across. The water lies in Northumberland County. The nearest mapped water is Long Ponds, 3 mi to the northeast.
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Top water on the chart: Break off the point, a drop-off in the 18 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (5 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (18 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (18 ft) | Blade bait, Hair jig |
Come spring, look for chain pickerel tight to the bank in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 5 to 18 ft. Start at Break off the point. It's a drop-off holding about 18 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A weedless spoon + trailer or a buzzbait is the honest summer answer here.
| 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 | Main-lake point (5 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Break off the point (18 ft) | Jigging spoon (through ice) |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 18 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| 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 | 10 to 30 ft | dawn | Break off the point (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (18 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 18 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts white perch in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 40 ft; cold water stacks them in 20 to 50 ft. Deep basin is the standout, a deep basin at roughly 45 ft, rated prime for fall white perch. Plan around early morning in the warm months. A small spinner rig drifted or a 1/8 oz jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | open water | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Break off the point (18 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Deep basin (45 ft) | Jigging spoon (small), Blade bait |
| Winter | 20 to 50 ft | dusk | Deep basin (45 ft) | Small rattle spoon, Tungsten + spikes |
