747-acre lake in Thunder Bay District, Ontario. The lake tops out around 72 ft. The depth data here comes from the Ontario MNRF survey of 1985 (a transect sounding survey). Species by species, here's what the data says the year looks like.
Dora Lake maps at 750 acres behind 18.1 miles of shoreline, with 32 islands in the mix. That shoreline is heavily fingered (development index 4.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 38% of this chart. Figure 3.8 mi of water from one end to the other, 1.1 mi at the beam. It sits in Thunder Bay District. Its nearest charted neighbour, Grew Lake, is 4 mi to the northeast.
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 16 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
