65-acre lake in Peterborough County, Ontario. The lake tops out around 6 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 65 acres of water rimmed by 3.9 miles of bank, broken up by 11 islands. That shoreline is heavily fingered (development index 3.5) — bays, points and pockets everywhere, which multiplies the fishable edge. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.8 mi end to end and 0.3 mi across at its widest. You'll find it in Peterborough County. The nearest mapped water is Little Bald Lake, 1 mi to the southwest.
Come spring, look for walleye tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates prime come winter. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 6 ft | dusk & dawn | Break off the point (1 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 6 ft | dusk & night | Break off the point (1 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 6 ft | dusk & dawn | Deep basin (6 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. If you only fish one area, make it Deep basin: a deep basin around 6 ft that scores prime in fall. 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 | 2 to 6 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, muskellunge run shallow here, mostly 2 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Winter muskellunge concentrate at Deep basin, a prime-rated deep basin around 6 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a double-10 bucktail or a topwater (walk-the-dog / creeper) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | dusk | Shallow bay flat (1 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 2 to 6 ft | dusk & dawn | Main-lake point (1 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 2 to 6 ft | midday & dusk | Break off the point (1 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 2 to 6 ft | midday | Deep basin (6 ft) | Large rubber, crawled slow |
The spring pattern is a shallow one: largemouth bass in 1 to 6 ft. The depth story barely changes: 2 to 6 ft through summer, 2 to 6 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 1 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 | 1 to 6 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 6 ft | dawn & dusk | Shallow bay flat (1 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 6 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 6 ft | midday | Break off the point (1 ft) | Blade bait, Jigging spoon |
Early season rock bass use the shallows, holding in 1 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 2 to 6 ft. The chart's best answer is Deep basin — deep basin, 6 ft, prime for winter. Best bite is the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 2 to 6 ft | dusk | Main-lake point (1 ft) | Ned rig (small), Marabou jig |
| Fall | 2 to 6 ft | midday | Break off the point (1 ft) | Small tube jig, Inline spinner |
| Winter | 2 to 6 ft | midday | Deep basin (6 ft) | Tungsten jig + plastic, Small spoon + spike |
Start shallow in spring: crappie sit in 2 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 6 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a jig trolled/spider-rigged or a small crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | midday & dawn | Shallow bay flat (1 ft) | 1/16 oz jig + tube, Curly-tail grub |
