Fishing Ivanhoe Lake: what the data says

4,639-acre lake in Sudbury District, Ontario. The lake tops out around 70 ft. The depth data here comes from the Ontario MNRF survey of 1980 (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 4,660 acres, worked by 76.4 miles of shoreline, with 14 islands in the mix. A development index of 8 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 68% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 22.8 mi long by 2.4 mi wide at the broadest reach. Sudbury District claims this one. If the bite dies, Tom Smith Lake is 3 mi to the east.
