Fishing Irwin Lake: what the data says

716-acre lake in Kenora 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.

Drawn out, this is 720 acres of water rimmed by 18.3 miles of bank, with 11 islands in the mix. An index of 4.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 68% of the surface — that's where the groceries are. Call it 3.5 mi long by 1.5 mi wide at the broadest reach. The water lies in Kenora District. The nearest mapped water is Frances Lake, 12 mi to the north.
