9-acre lake in Nipissing District, Ontario. The lake tops out around 29 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 9 acres wrapped in 0.7 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 52% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Nipissing District claims this one. If the bite dies, Opeongo Lake is 2 mi to the northeast.
Spring splake on Marmot Lake hold shallow, usually 5 to 25 ft. They move out to 9 to 29 ft in summer and finish the year down in 6 to 29 ft. Put Break off the point first on the milk run — a drop-off near 13 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon at the thermocline or a white tube jig (deep).

|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 9 to 29 ft | dawn & dusk | Break off the point (13 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
