Fishing Blackstone Lake: what the data says

6,703-acre lake in Kenora District, Ontario. The lake tops out around 72 ft. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey). The exact depth survey is published on its own because no defensible water-specific species roster was found.

The outline encloses 6,735 acres, worked by 161.6 miles of shoreline, broken up by 125 islands. A development index of 14 means a maze of bays and points: far more casting targets than a round bowl of the same size. Littoral water — the productive band under ~15 ft — makes up 71% of this chart. Call it 9.7 mi long by 6.6 mi wide at the broadest reach. It sits in Kenora District. Its nearest charted neighbour, Austin Lake, is 6 mi to the north.
