Fishing Martineau Lake: what the data says

45-acre lake in Renfrew County, Ontario. The lake tops out around 5 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The exact depth survey is published on its own because no defensible water-specific species roster was found.

The drawn water covers 45 acres wrapped in 1.6 miles of bank, with a single island in the mix. A middling shoreline index (1.8) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.6 mi end to end and 0.3 mi across at its widest. It sits in Renfrew County. Murphys Lake sits 2 mi west — the closest neighbouring chart.
