76-acre lake in Frontenac County, Ontario. The lake tops out around 62 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 77 acres wrapped in 2.6 miles of bank, with a single island in the mix. A middling shoreline index (2.1) gives it some bays to work without being a maze. About 31% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. Frontenac County claims this one. Miner Lake sits 1 mi east — the closest neighbouring chart.
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 19 to 62 ft before dropping to 20 to 60 ft for winter. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 53 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (28 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 19 to 62 ft | dawn | Deep basin (53 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (28 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (53 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
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 6 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 (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Put Main-lake point first on the milk run — a point near 16 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (16 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (28 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (16 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (28 ft) | Blade bait, Hair jig |
In spring, rock bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 20 ft before dropping to 12 to 30 ft for winter. Summer rock bass concentrate at Main-lake point, a prime-rated point around 16 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.
| 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 | 5 to 20 ft | dusk | Main-lake point (16 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (16 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (28 ft) | Tungsten jig + plastic, Small spoon + spike |
Early season bluegill use the shallows, holding in 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (53 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
