3,408-acre lake in Ontario. The lake tops out around 30 ft. The depth data here comes from the Ontario MNRF survey of 1967, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Dalrymple Lake maps at 3,423 acres behind 27.8 miles of shoreline, broken up by 15 islands. That shoreline is heavily fingered (development index 3.4) — bays, points and pockets everywhere, which multiplies the fishable edge. 74% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 6.9 mi end to end and 2.1 mi across at its widest. It sits in Kawartha Lakes. Its nearest charted neighbour, Young Lake, is 6 mi to the northwest.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Sharp break, a drop-off in about 22 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft | dusk & dawn | Sharp break (22 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft | dusk & night | Sharp break (22 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft | dusk & dawn | Deep basin (30 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 30 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Gravel shoal (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (19 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (5 ft) | Tip-ups, Large jigging spoon |
Early season muskellunge use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 9 to 30 ft. Put Sharp break first on the milk run — a drop-off near 22 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a double-10 bucktail or a topwater (walk-the-dog / creeper) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (1 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Sharp break (22 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 8 to 30 ft | midday & dusk | Sharp break (22 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 9 to 30 ft | midday | Deep basin (30 ft) | Large rubber, crawled slow |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 9 to 30 ft one. The chart's best answer is Sharp break — drop-off, 22 ft, prime for winter. Best bite is 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 | Gravel shoal (3 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Sharp break (22 ft) | Drop shot (goby/minnow), Ned rig |

| Winter | 9 to 30 ft | midday | Sharp break (22 ft) | Blade bait, Hair jig |
Spring largemouth bass on Dalrymple Lake hold shallow, usually 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 9 to 30 ft. Put Sharp break first on the milk run — a drop-off near 22 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
