37-acre lake in Algoma District, Ontario. The lake tops out around 3 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What the data behind the map says about each species, season by season:
The drawn water covers 37 acres wrapped in 1.4 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.6 mi of water from one end to the other, 0.2 mi at the beam. It sits in Algoma District. If the bite dies, Bourinot Lake is 1 mi to the southwest.
The spring pattern is a shallow one: walleye in 1 to 3 ft. The depth story barely changes: 1 to 3 ft through summer, 1 to 3 ft in winter. The spot to know is Break off the point, a drop-off in about 3 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 1 to 3 ft | dusk & dawn | Break off the point (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 1 to 3 ft | dusk & night | Break off the point (3 ft) | Jigging rap, Jig + big minnow |
| Winter | 1 to 3 ft | dusk & dawn | Deep basin (3 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 1 to 3 ft. Summer keeps them at 1 to 3 ft, and they winter in 1 to 3 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | midday & dawn | Shallow bay flat (2 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) |
Early season northern pike use the shallows, holding in 1 to 3 ft. Even in summer they hold at 1 to 3 ft; winter keeps them in 1 to 3 ft. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 1 to 3 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 1 to 3 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 1 to 3 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |

South Moosehorn Lake is about 3 ft (1 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, yellow perch, northern pike on South Moosehorn Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Break off the point is the top-rated area: a drop-off in about 3 ft of water that rates prime for walleye in fall. The interactive chart above rates every spot for each species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
