Rating depth structure for pumpkinseed.

49-acre lake in Sudbury District, Ontario. The lake tops out around 23 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
The drawn water covers 49 acres wrapped in 2.6 miles of bank. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 77% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.9 mi long by 0.3 mi wide at the broadest reach. Sudbury District claims this one. Its nearest charted neighbour, Horseshoe Lake, is 1 mi to the north.
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for pumpkinseed in spring. Plan around the evening and early morning in the warm months. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
