83-acre lake in Ontario. The lake tops out around 10 ft. The depth data here comes from the Ontario MNRF survey of 2006 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 83 acres of water rimmed by 1.7 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 0.7 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Greater Sudbury / Grand Sudbury. For a second option, Hannah Lake lies 1 mi south.
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 3 to 10 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.

|---|---|---|---|---|
| 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 | 3 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
