166-acre lake in Peterborough County, Ontario. The lake tops out around 26 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.
Traced from the shoreline, Lost Lake runs 167 acres with 4.7 miles of edge, broken up by 9 islands. The 2.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 66% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 1.3 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Peterborough County. The nearest mapped water is Cordova Lake, 2 mi to the northeast.
6 pieces of structure are mapped here — Deep basin, around 26 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Lost Lake specifically, so confirm the current rules before you fish.
