Fishing Boundary Lake: what the data says

225-acre lake in Sudbury District, Ontario. The lake tops out around 30 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 outline encloses 226 acres, worked by 8.5 miles of shoreline, broken up by 13 islands. An index of 4.1 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Roughly 80% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.8 mi, about 0.7 mi across. Sudbury District claims this one. Its nearest charted neighbour, David Lake, is 1 mi to the northeast.
