Fishing Cobham Lake: what the data says

6,060-acre lake in Kenora District, Ontario. The lake tops out around 69 ft. The depth data here comes from the Ontario MNRF survey of 1977, a decades-old survey (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 6,087 acres, worked by 131.3 miles of shoreline — 50 islands included. With a shoreline index of 12, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 85% of the surface — that's where the groceries are. The basin spans about 16.2 mi end to end and 7.4 mi across at its widest. It sits in Kenora District. If the bite dies, Cobham River is 9 mi to the west.
