37-acre lake in Nipissing 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.
The outline encloses 37 acres, worked by 1.3 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 42% of this chart. Figure 0.6 mi of water from one end to the other, 0.2 mi at the beam. Nipissing District claims this one. If the bite dies, Whitethroat Lake is 0 mi to the southwest.
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 33 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 (10 ft) | 1/8 oz jig + minnow, Hair jig |

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