Fishing South Otter Lake: what the data says

107-acre lake in Frontenac County, Ontario. The lake tops out around 25 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.

The drawn water covers 107 acres wrapped in 3.7 miles of bank, broken up by 3 islands. An index of 2.6 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 53% of the surface — that's where the groceries are. Call it 1.2 mi long by 0.3 mi wide at the broadest reach. Frontenac County claims this one. If the bite dies, Pearkes Lake is 0 mi to the southwest.
