117-acre lake in Ontario. The lake tops out around 7 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. 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.
Duck Lake maps at 118 acres behind 2.6 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.1 mi, about 0.3 mi across. Kawartha Lakes claims this one. Its nearest charted neighbour, Raven Lake, is 4 mi to the southeast.
Spring muskellunge on Duck Lake hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 6 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 3 to 12 ft | dusk | Shallow bay flat (2 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 2 to 7 ft chart-limited; documented 8 to 25 ft | dusk & dawn | Main-lake point (3 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 2 to 7 ft chart-limited; documented 8 to 30 ft | midday & dusk | Break off the point (6 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 2 to 7 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (7 ft) | Large rubber, crawled slow |
Spring smallmouth bass on Duck Lake hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. The chart's best answer is Main-lake point — point, 3 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 | 2 to 7 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (6 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 7 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (3 ft) | Jerkbait, Blade bait |
| Winter | 2 to 7 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (6 ft) | Blade bait, Hair jig |
Early season largemouth bass use the shallows, holding in 1 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 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.

Duck Lake is about 7 ft (2 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target muskellunge, smallmouth bass, largemouth bass on Duck Lake.
Break off the point is the top-rated area: a drop-off in about 6 ft of water that rates prime for muskellunge in fall. Open the map above to see every rated spot for each species and season.
For muskellunge, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
