17-acre lake near Paroisse d'Addington. Government of New Brunswick lake depth survey. The lake tops out around 4 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
On the chart, Otter Lake draws 17 acres inside 0.9 miles of shoreline. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. The water lies in Northumberland County. For a second option, Grants Lake lies 1 mi north.
Spring puts smallmouth bass in skinny water — 1 to 4 ft is the zone. Summer fish stay in 1 to 4 ft, and winter fish hold in 1 to 4 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 2 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 1 to 4 ft | dawn & dusk | Break off the point (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 1 to 4 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 1 to 4 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
Early season chain pickerel use the shallows, holding in 1 to 4 ft. Even in summer they hold at 1 to 4 ft; winter keeps them in 1 to 4 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a weedless spoon + trailer or a buzzbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dawn | Shallow bay flat (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (2 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 1 to 4 ft | midday & dawn | Shallow bay flat (2 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 1 to 4 ft | dawn | Shallow bay flat (2 ft) | Jigging spoon (through ice) |
Spring yellow perch on Otter Lake hold shallow, usually 1 to 4 ft. Depth-wise the year is flat: 1 to 4 ft in summer, 1 to 4 ft once it turns cold. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 4 ft | dawn | Deep basin (4 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 4 ft | midday | Deep basin (4 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 4 ft | midday & dawn | Deep basin (4 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: brook trout sit in 1 to 4 ft that time of year. They don't go far with the seasons — 1 to 4 ft covers summer, 1 to 4 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 4 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 1 to 4 ft | dawn & dusk | Deep basin (4 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 4 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 4 ft | dawn | Deep basin (4 ft) | Small jigging spoon, Tungsten jig + plastic |

Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout on Otter 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. Scroll up to the map for the complete spot list by 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.
