27-acre lake in Sudbury District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 27 acres of water rimmed by 1 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 38% of the surface — that's where the groceries are. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. The water lies in Sudbury District.

Spring yellow perch on Partridge 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 15 to 35 ft. The chart's best answer is Break off the point — drop-off, 30 ft, prime for summer. Prime time lands in 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 |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft.

A bucktail or a weedless spoon over cabbage covers the summer program.

This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Main-lake point is the top-rated area: a point in about 11 ft of water that rates prime for smallmouth bass in fall. Every other rated spot, per species and season, is on the map above.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
