43-acre lake in Algoma District, Ontario. The lake tops out around 33 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. The rest of this page walks each species through its year, using the map's own scoring.
Martin Lake maps at 43 acres behind 1.5 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 68% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.5 mi of water from one end to the other, 0.2 mi at the beam. Algoma District claims this one. Spider L. sits 1 mi southwest — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Deep basin. It's a deep basin holding about 28 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
