Fishing Sophia Lake: what the data says

36-acre lake in Peterborough County, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1970, 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 37 acres, worked by 2.2 miles of shoreline, broken up by an island. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. 42% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.7 mi long by 0.2 mi wide at the broadest reach. Peterborough County claims this one. If the bite dies, Little Long Lake is 3 mi to the southwest.
