Rating depth structure for smallmouth bass.

18-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 4 ft. The depth chart comes from Government of New Brunswick DNRED 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.
Spikehorn Lake maps at 18 acres behind 0.9 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. It sits in Northumberland County. If the bite dies, McKendrick Lake is 1 mi to the east.
Spring smallmouth bass on Spikehorn 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. Put Deep basin first on the milk run — a deep basin near 4 ft that grades good for winter. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
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 | 1 to 4 ft chart-limited; documented 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 1 to 4 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 1 to 4 ft chart-limited; documented 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 1 to 4 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (4 ft) | Blade bait, Hair jig |
In spring, chain pickerel run shallow here, mostly 1 to 4 ft. Summer keeps them at 1 to 4 ft, and they winter in 1 to 4 ft. Winter chain pickerel concentrate at Deep basin, a good-rated deep basin around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a weedless spoon + trailer or a buzzbait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft chart-limited; documented 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 1 to 4 ft chart-limited; documented 3 to 15 ft | dawn & dusk | open water | Weedless spoon + trailer, Buzzbait |
| Fall | 1 to 4 ft chart-limited; documented 4 to 15 ft | midday & dawn | open water | Jerkbait along weed edges, Spinnerbait |
| Winter | 1 to 4 ft chart-limited; documented 5 to 18 ft | dawn | Deep basin (4 ft) | Jigging spoon (through ice) |
Spring puts yellow perch 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. Deep basin is the standout, a deep basin at roughly 4 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 4 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (4 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 4 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (4 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 4 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (4 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, brook trout slide up into 1 to 4 ft. There's no big seasonal slide here — summer means 1 to 4 ft, winter 1 to 4 ft. If you only fish one area, make it Deep basin: a deep basin around 4 ft that scores good in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.

Spikehorn Lake is about 4 ft (1 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 Spikehorn 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 4 ft of water that rates prime for yellow perch in fall. Open the map above to see every rated 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.
