4,042-acre lake in Peterborough County, Ontario. The lake tops out around 18 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Start at Break off the point. It's a drop-off holding about 8 ft of water and rates prime come fall. 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 | 4 to 15 ft | dusk & dawn | Shoreline point (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 18 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 18 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 18 ft | dusk & dawn | Deep basin (18 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 18 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 | 3 to 12 ft | midday & dawn | Back-bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 18 ft | dawn | Deep basin (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 18 ft | midday | Deep basin (18 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 18 ft | midday & dawn | Deep basin (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, muskellunge run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. Fall muskellunge concentrate at Break off the point, a prime-rated drop-off around 8 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 | 3 to 12 ft | dusk | Back-bay flat (2 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 5 to 18 ft | dusk & dawn | Shoreline point (6 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 5 to 18 ft | midday & dusk | Break off the point (8 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 5 to 18 ft | midday | Deep basin (18 ft) | Large rubber, crawled slow |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Shoreline point, a point in the 6 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 (3 ft) | Ned rig, Tube jig |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 18 ft | midday & dawn | Shoreline point (6 ft) | Jerkbait, Blade bait |
| Winter | 5 to 18 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. The spot to know is Back-bay flat, a weed flat in about 2 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 | Back-bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shoreline point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 18 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
Early season rock bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 18 ft game here, winter a 5 to 18 ft one. The chart's best answer is Shoreline point — point, 6 ft, prime for summer. 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 | 2 to 10 ft | midday & dawn | Main-lake point (3 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 18 ft | dusk | Shoreline point (6 ft) | Ned rig (small), Marabou jig |
