Fishing Hardiman Lake: what the data says

1,575-acre lake in Sudbury District, Ontario. The lake tops out around 39 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.

Hardiman Lake maps at 1,582 acres behind 28 miles of shoreline — 24 islands included. A development index of 5 means a maze of bays and points: far more casting targets than a round bowl of the same size. 88% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 3.3 mi of water from one end to the other, 1.8 mi at the beam. Sudbury District claims this one. Arbeesee Lake sits 6 mi southeast — the closest neighbouring chart.
