106-acre lake in Thunder Bay District, Ontario. The lake tops out around 14 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
On the chart, Whitelily Lake draws 107 acres inside 2.6 miles of shoreline. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 0.7 mi, about 0.5 mi across. The water lies in Thunder Bay District. Closest neighbour on DepthScout: Timmus Lake, 1 mi north of here.
Spring yellow perch on Whitelily Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
