121-acre lake in Parry Sound District, Ontario. The lake tops out around 28 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 122 acres, worked by 6.4 miles of shoreline. The 4.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 74% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1.3 mi of water from one end to the other, 0.6 mi at the beam. Parry Sound District claims this one. Reservoir L. sits 1 mi southwest — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 8 to 28 ft, wintering in 8 to 28 ft. Top water on the chart: Break off the point, a drop-off in the 13 ft range, prime in fall. Time it for the evening and early morning. 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 | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 28 ft | dusk & dawn | Break off the point (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 28 ft | dusk & night | Break off the point (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 28 ft | dusk & dawn | Deep basin (24 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 8 to 28 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Fall | 8 to 28 ft | midday | Deep basin (24 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 28 ft | midday & dawn | Deep basin (24 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in 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 | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 8 to 28 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

Summer rock bass concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in the evening and you'll meet the bite. You won't need more than a ned rig (small) or a marabou jig most summer days.

Anglers target walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed on South River.
Break off the point is the top-rated area: a drop-off in about 13 ft of water that rates prime for walleye in fall. The map above holds the full rated-spot list for every 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.
