167-acre lake in Sudbury District, Ontario. The lake tops out around 64 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 167 acres wrapped in 4.3 miles of bank — one island included. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 74% of this chart, as modeled. Figure 0.9 mi of water from one end to the other, 0.7 mi at the beam. Sudbury District claims this one. If the bite dies, Hutt L. 11 is 2 mi to the northeast.
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 29 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (16 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
