29-acre lake in Nipissing District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 30 acres, worked by 1.3 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. 58% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. Nipissing District claims this one. If the bite dies, Philip Lake is 1 mi to the north.
Spring brook trout on Charles Lake hold shallow, usually 2 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 20 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
