197-acre lake in Frontenac County, Ontario. The lake tops out around 21 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
Inverary Lake maps at 196 acres behind 4 miles of shoreline. With a 2.1 development index there's bank structure worth casting at, in moderation. 87% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 1.7 mi of water from one end to the other, 0.4 mi at the beam. It sits in Frontenac County. Round Lake sits 2 mi northeast — the closest neighbouring chart.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 6 to 21 ft; cold water stacks them in 6 to 21 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| 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 |
| Summer | 6 to 21 ft | dawn | Deep basin (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 21 ft | midday | Deep basin (18 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 21 ft | midday & dawn | Deep basin (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. They move out to 6 to 21 ft in summer and finish the year down in 6 to 21 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 6 to 21 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 21 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 6 to 21 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 6 to 21 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 21 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 6 to 21 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 early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| 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 | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 21 ft | midday | Deep basin (18 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. As the season builds they drop to 2 to 10 ft, wintering in 6 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for the evening and early morning. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| 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 | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (18 ft) | Tungsten ice jig + plastic, Tiny spoon |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 18 ft.
