1,067-acre lake in Kenora District, Ontario. The lake tops out around 220 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, Mather Lake runs 1,072 acres with 33.8 miles of edge — 41 islands included. The 7.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 69% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 3.4 mi of water from one end to the other, 2.2 mi at the beam. You'll find it in Kenora District. The nearest mapped water is Trident Lake, 5 mi to the south.
8 pieces of structure are mapped here — Deep basin, around 219 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 Mather Lake specifically, so confirm the current rules before you fish.
