230-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 3 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. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Guagus Lake draws 231 acres inside 4 miles of shoreline. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.3 mi, about 0.7 mi across. The water lies in Northumberland County. For a second option, Whitney Pond lies 2 mi southeast.
The spring pattern is a shallow one: smallmouth bass in 1 to 3 ft. The depth story barely changes: 1 to 3 ft through summer, 1 to 3 ft in winter. Top water on the chart: Main-lake point, a point in the 2 ft range, prime in fall. 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 | 1 to 3 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 1 to 3 ft | dawn & dusk | Break off the point (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 1 to 3 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 1 to 3 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
Come spring, look for chain pickerel tight to the bank in 1 to 3 ft. Through summer count on 1 to 3 ft; the winter hold is 1 to 3 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. 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 | 1 to 3 ft | midday & dawn | Shallow bay flat (3 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 1 to 3 ft | dawn & dusk | Shallow bay flat (3 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 1 to 3 ft | midday & dawn | Shallow bay flat (3 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 1 to 3 ft | dawn | Shallow bay flat (3 ft) | Jigging spoon (through ice) |
When the water first warms, yellow perch slide up into 1 to 3 ft. There's no big seasonal slide here — summer means 1 to 3 ft, winter 1 to 3 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. 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 | 1 to 3 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 3 ft | dawn | Deep basin (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 3 ft | midday | Deep basin (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 3 ft | midday & dawn | Deep basin (3 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts brook trout in skinny water — 1 to 3 ft is the zone. Summer fish stay in 1 to 3 ft, and winter fish hold in 1 to 3 ft. Deep basin is the standout, a deep basin at roughly 3 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 | 1 to 3 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 1 to 3 ft | dawn & dusk | Deep basin (3 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 3 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 3 ft | dawn | Deep basin (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts white perch in skinny water — 1 to 3 ft is the zone. Summer fish stay in 1 to 3 ft, and winter fish hold in 1 to 3 ft. Deep basin is the standout, a deep basin at roughly 3 ft, rated prime for summer 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 | 1 to 3 ft | dusk | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 1 to 3 ft | dawn | Deep basin (3 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |

Guagus Lake is about 3 ft (1 m) deep at its deepest point. The depth chart here comes from real state fisheries GPS surveys, so the contours reflect measured depths.
Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout, white perch on Guagus 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.
Main-lake point is the top-rated area: a point in about 2 ft of water that rates prime for smallmouth bass in fall. The interactive chart above rates every spot for each species and season.
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.
