105-acre lake in Nipissing District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What follows comes from the same scoring engine that paints the spots above.
Sunday Lake maps at 106 acres behind 3.2 miles of shoreline, with a single island in the mix. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 60% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.9 mi, about 0.6 mi across. Nipissing District claims this one. Its nearest charted neighbour, Little Rock Lake, is 1 mi to the west.
