392-acre lake in Parry Sound District, Ontario. The lake tops out around 80 ft. The depth data here comes from the Ontario MNRF survey of 1975, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Duck Lake draws 393 acres inside 9.7 miles of shoreline, with 7 islands in the mix. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. 43% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 1.7 mi long by 0.9 mi wide at the broadest reach. You'll find it in Parry Sound District. Closest neighbour on DepthScout: Wauquimakog Lake, 2 mi northwest of here.
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Main-lake point first on the milk run — a point near 23 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (12 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Main-lake point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

Spring yellow perch on Duck Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Main-lake point is the standout, a point at roughly 23 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (12 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (23 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (23 ft) | Jerkbait, Blade bait |

It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
