562-acre lake near Gagetown Parish. Government of New Brunswick lake depth survey. The lake tops out around 16 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.
On the chart, Harts Lake draws 562 acres inside 9.2 miles of shoreline. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. About 93% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 2 mi, about 1.1 mi across. You'll find it in Queens County. Closest neighbour on DepthScout: Maquapit Lake, 7 mi north of here.
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 5 to 16.1 ft; cold water stacks them in 5 to 16.1 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| 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 |
When the water first warms, chain pickerel slide up into 2 to 10 ft. Summer is a 3 to 15 ft game here, winter a 4 to 16.1 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a weedless spoon + trailer or a buzzbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (3 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 4 to 16.1 ft | dawn | Shallow bay flat (3 ft) | Jigging spoon (through ice) |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 5 to 16.1 ft in summer and finish the year down in 5 to 16.1 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | 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) |
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 5 to 16.1 ft, and winter fish settle into 2 to 16.1 ft. Deep basin is the standout, a deep basin at roughly 14 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| 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 |

You won't need more than a small spinner rig drifted or a 1/8 oz jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner (silver) |
