917-acre lake in Nipissing District, Ontario. The lake tops out around 100 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.
Biggar Lake maps at 921 acres behind 11.1 miles of shoreline, with a single island in the mix. The 2.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 39% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 3.7 mi of water from one end to the other, 1.1 mi at the beam. Nipissing District claims this one. Kawa Lake sits 2 mi northeast — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 28 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.

|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |

The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
