122-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 72 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 122 acres wrapped in 2.8 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 19% of this chart, as modeled. Call it 0.8 mi long by 0.6 mi wide at the broadest reach. Muskoka District Municipality claims this one. Horners Lake sits 1 mi southwest — the closest neighbouring chart.
Spring lake trout on Blue Chalk Lake hold shallow, usually 10 to 40 ft. They move out to 22 to 72 ft in summer and finish the year down in 18 to 72 ft. Put Deep basin first on the milk run — a deep basin near 61 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 61 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Put Main-lake point first on the milk run — a point near 18 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
