48-acre lake in Nipissing District, Ontario. The lake tops out around 15 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
Little Rock Lake maps at 49 acres behind 1.3 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. End to end it runs roughly 0.5 mi, about 0.3 mi across. Nipissing District claims this one. Its nearest charted neighbour, Pond Lake, is 1 mi to the southwest.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
