60-acre lake in Renfrew County, Ontario. The lake tops out around 29 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 61 acres of water rimmed by 3.1 miles of bank. An index of 2.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 91% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 1.3 mi with a 0.2-mi widest point. You'll find it in Renfrew County. For a second option, Sec Lake lies 1 mi west.
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 9 to 29 ft game here, winter a 9 to 29 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. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| 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 | 9 to 29 ft | dawn | Deep basin (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 29 ft | midday | Deep basin (25 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 29 ft | midday & dawn | Deep basin (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 9 to 29 ft before dropping to 9 to 29 ft for winter. The spot to know is Main-lake point, a point in about 8 ft of water that rates prime for smallmouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| 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 | 9 to 29 ft | dawn & dusk | Break off the point (13 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 9 to 29 ft | midday | Break off the point (13 ft) | Blade bait, Hair jig |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 9 to 29 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 the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| 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 (13 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 | 9 to 29 ft | midday | Break off the point (13 ft) | Blade bait, Jigging spoon |
Spring pumpkinseed on Mallard Lake hold shallow, usually 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| 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 | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Deep basin is the standout, a deep basin at roughly 25 ft, rated prime for winter brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (3 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (25 ft) |
