80-acre lake in Peterborough County, Ontario. The lake tops out around 50 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 81 acres of water rimmed by 3.1 miles of bank, with 5 islands in the mix. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 27% of the water is 15 ft or less, the band where the food chain lives. Figure 0.8 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Peterborough County. The nearest mapped water is McGee Lake, 2 mi to the northeast.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 8 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (50 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Top water on the chart: Main-lake point, a point in the 10 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (10 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (11 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (10 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (11 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 8 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (10 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (11 ft) | Blade bait, Jigging spoon |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — weed flat, 8 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (8 ft) | Micro jig under a float, Tiny beetle-spin |
