Rating depth structure for pumpkinseed.

53-acre lake in Lanark County, Ontario. The lake tops out around 3 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Stewart Lake runs 53 acres with 1.2 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. The water lies in Lanark County. Closest neighbour on DepthScout: Gillies Lake, 3 mi west of here.
Come spring, look for pumpkinseed tight to the bank in 1 to 3 ft. Through summer count on 1 to 3 ft; the winter hold is 1 to 3 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 1 to 3 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 1 to 3 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 1 to 3 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
4 pieces of structure are mapped here — Shallow bay flat, around 3 ft, is the deepest of them.
