17-acre lake in Frontenac County, Ontario. The lake tops out around 12 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Drawn out, this is 19 acres of water rimmed by 0.8 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 0.3 mi, about 0.2 mi across. The water lies in Frontenac County. Closest neighbour on DepthScout: Tetsmine L., 0 mi northwest of here.
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Summer fish stay in 4 to 12 ft, and winter fish hold in 4 to 12 ft. Winter smallmouth bass concentrate at Shoreline break, a prime-rated drop-off around 5 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 | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 4 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 12 ft | midday & dawn | Shoreline break (5 ft) | Jerkbait, Blade bait |
| Winter | 4 to 12 ft | midday | Shoreline break (5 ft) | Blade bait, Hair jig |
When the water first warms, rock bass slide up into 2 to 10 ft. By summer they slide out to 3 to 12 ft, and by winter most fish are in 4 to 12 ft. If you only fish one area, make it Shoreline break: a drop-off around 5 ft that scores prime in fall. In summer the feeding windows fall in the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 3 to 12 ft | dusk | Shoreline break (5 ft) | Ned rig (small), Marabou jig |
| Fall | 4 to 12 ft | midday | Shoreline break (5 ft) | Small tube jig, Inline spinner |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Tungsten jig + plastic, Small spoon + spike |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 3 to 12 ft, wintering in 4 to 12 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 3 to 12 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 12 ft | midday | Shoreline break (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 4 to 12 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 the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 3 to 12 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 12 ft | dawn | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |

Shoreline break is the top-rated area: a drop-off in about 5 ft of water that rates prime for smallmouth bass in winter. The map above holds the full rated-spot list for every 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.
