125-acre lake in Nipissing District, Ontario. The lake tops out around 7 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1983 (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 124 acres wrapped in 2.3 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Figure 0.9 mi of water from one end to the other, 0.4 mi at the beam. Nipissing District claims this one. Its nearest charted neighbour, Wasi Lake, is 5 mi to the north.
The spring pattern is a shallow one: walleye in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. Top water on the chart: Break off the point, a drop-off in the 3 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
