87-acre lake in Peterborough County, Ontario. The lake tops out around 39 ft. The depth data here comes from the Ontario MNRF survey of 1981 (a transect sounding survey). Species by species, here's what the data says the year looks like.
The drawn water covers 88 acres wrapped in 3.2 miles of bank, broken up by an island. The 2.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 48% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.8 mi of water from one end to the other, 0.5 mi at the beam. Peterborough County claims this one. If the bite dies, Cherry Lake is 1 mi to the north.
Spring smallmouth bass on Turtle Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 12 to 39 ft. The chart's best answer is Main-lake point — point, 12 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (12 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (12 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (12 ft) | Jerkbait, Blade bait |
| Winter | 12 to 39 ft | midday | Break off the point (39 ft) | Blade bait, Hair jig |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
