184-acre lake in Peterborough County, Ontario. The lake tops out around 110 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Drawn out, this is 185 acres of water rimmed by 4.2 miles of bank, broken up by an island. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 24% of this chart. End to end it runs roughly 0.9 mi, about 0.7 mi across. You'll find it in Peterborough County. The nearest mapped water is Greens Lake, 1 mi to the north.
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. Summer is a 40 to 80 ft game here, winter a 20 to 60 ft one. Start at Break off the point. It's a drop-off holding about 22 ft of water and rates prime come winter. The feeding windows run early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (22 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (108 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

Spring yellow perch on Picard 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. Put Back-bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|

The spring pattern is a shallow one: muskellunge in 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 15 to 35 ft for winter. The spot to know is Break off the point, a drop-off in about 22 ft of water that rates prime for muskellunge in fall. Plan around the evening and early morning in the warm months. Summer baits: a double-10 bucktail or a topwater (walk-the-dog / creeper) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Back-bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Main-lake point (17 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (22 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 15 to 35 ft | midday | Break off the point (22 ft) | Large rubber, crawled slow |
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 17 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 (5 ft) | Ned rig, Tube jig |

Keep a micro tube or a sponge spider (fly) rigged through the warm months.
